 Andrew C. Lawion. 
 
 Ill the year 1H!)1, Mr. II. L. Smyth published an interesting 
 paiMjr' on the geology of Steeprock lake, in wliich he cla3gifie<l the 
 rocks there exposed i'lto thn>e principal sroiips: — 
 
 (!) The Basement Complex, consisting of granites and gneisses 
 which typically are medium grained, hornblendic and granitoid 
 with faint foliation. Locally they present considerable variations 
 in composition and very great variations in structure. 
 
 (2) The Steeprock series, showing a thickness of 5,<H)0 feet. 
 
 (.■?) The Atikokan series, a succession of later granitoid porphy- 
 ries and massive hornblende rocks. 
 
 The Steeprock series rests unconformably upon the basement 
 cimiplex, and is subdivided into nine formations, according to the 
 following scheme, arranged in ascen<liiig sequence: — • 
 1. ("onglomenite. 
 II. Lower limestone. 
 
 III. Ferruginous formation. 
 
 IV. Interbedded crystalline traps. 
 V. I'pjier calcareous green schist. 
 
 VI. I'lifK'r ''onglomerate. 
 VII. (ireenstones and proeiistnne schists. 
 Vlll. Agglomerate. 
 
 IX. Dark grey clay slate. 
 The sequence of these formations and their structural relations 
 formed the chief subject matter of ilr. Smyth's paper, and the 
 discussion of his third division, the Atikokan series, was deferred. 
 The paper was not only interesting, but it was important from a 
 general point of view as an announcement and description of a 
 
 1891.

 series of rocks hitherto unrecognized in the Archaean of that part of 
 Canada. This fact has attracted a number of geologists to Steep- 
 rock lake, and several references to the series are to be found in 
 the literature of the region. The general question raised in all of 
 these is the relation of the Steeprock series to the Keewatin. 
 Snr.yth made perfectly clear that the Steeprock series rested uncon- 
 formably upon his basement complex with a basal conglomerate 
 reposing upou an eroded surface. But in that basement complex 
 he recognized no Keewatin, but only those granites and gneisses 
 which are usually referred io as Laurentian. The areal limits of 
 the Steeprock series to the south and southwest were left unde- 
 fined. In these directions, however, the rocks of the series are 
 cuntinuous with and indistinguishable from the Keewatin, and to 
 any geologist who became familiar with this fact the whole implica- 
 tion of Smyth's interpretation of the geology was that the series 
 was in part a local facies of the Keewatin and in part a normal 
 fncies, and that the Keewatin was, therefore, unconformable upon 
 rocks of the Laurentian type and habitus. 
 
 Mr. W. H. C. Smyth,' after an expmination of the series, 
 accepted Smyth's descriptions and classification, saying : ' The work 
 done by the writer in connexion with the rocks of this series suggests 
 no important modification of them.' But he expressed the opinion 
 that the Steeprock series was later than the Keewatin; a question 
 upon which H. L. Smyth was silent. He did not, however, locate 
 the contact of tho Steeprock and Keewatin : ' The unconformity 
 above the Keewatin schists of the Seine river to the southwest is 
 not at all obvious. Lithologically the green traps and schists of the 
 two series are strikingly similar and could not probably be separated 
 by the most careful study.' 
 
 Coleman,* in 1897, regarded the Steeprock series as part of 
 the Keewatin. He says : ' The water-formed elastics of the Kee- 
 watin are of great variety, including limestones, quartzites, slates, 
 grits, graywackes, breccias, and pebble and boulder conglomerates. 
 The limestones are, however, of limited extent, being found in any 
 thickness only at Steeprock lake, 70 miles east of Rainy lake, 
 where there is a small area differing both petrographically and 
 structurally from the rest of the region. These limestones have a

 very modem look, being scarcely at all crystalline in appearance, 
 having cherty layers in grey limestone at some points and black, 
 very carbonaceous beds at others. One almost expects to discover 
 fossils in them, but none liave been found.' He makes no dissent 
 from the ninefold subdivision of the series proposed by Smyth, and 
 accepts the letter's interpretation of the structure. 
 
 Mclnnes,' in 1899, accepts Smyth's ninefold subdivision of tlie 
 Steeprock series, and classifies tlie rocks of the series with the 
 Keewatin as forming the upper division of the latter; although 
 they are believed to be of later age than the great bulk of the Kee- 
 watin strata. 
 
 In 1911, Van Hise and Leith' give a summary statement of the 
 geology of Steeprock lake, in which the Steeprock series is 
 correlated with the lower Iluronian, and is said to rest unconform- 
 ably upon the Laurentian and Keewatin. But the series is said to 
 be principally exposed on the south and west shores of the lake, 
 where, as a matter of fact, the rocks are nearly all Keewatin, so that 
 it is evident that the areal distribution of the series given by Smyth 
 is accepted, the unconformity upon the Keewatin being inferred 
 from the presence of Keewatin pebbles in the basal conglomerate. 
 Smyth's ninefold subdivision of the series is quoted; but 'Some of 
 the greenstones and greenstone schists included by Smyth in the 
 lower Huronian are regarded by the authors as, at least in part, 
 Keewatin.' 
 
 During the past summer I took occasion to spend a few days 
 at Steeprock lake for the purpose of acquainting myself with some 
 of the features described by Smyth, and for my guidance I had a 
 copy of bis paper, and the map that accompanies it. As a result of 
 my visit, I am happily able to confirm the most important part of 
 his conclusions, particularly as to the existence of the series as a 
 distinct member of the Archscan, and its unconformable relation to 
 a granite-gneiss of the basement complex. On the other hand, the 
 observations that I uade, while by no means exhausting the field, 
 compel me to place an interpretation upon the stratigraphy and 
 struct^.-e quite different from that of Smyth, and enable me to 
 clear up the question of the relation of the series to the Keewatin,

 the latter being a large j>nrt of tho basement upon whieli the Steep- 
 rock series was uiieonfurmably deposited. 
 
 I approached Steeprock lake from the west, coming up the 
 Seine river from Rainy lake. In doing so I traced out nearly con- 
 tinuously the geological boundary between the Keewatin of Rainy 
 lake and a series of quartzites and slates which for convenient 
 reference I shall here call the Seine series. The Seine series lies 
 to the south of the Keewatin, and is poet-Keewatin in age. The 
 contact between the two series is marked not only by the striking 
 contrast in the general character and physical appearance of the 
 rocks, but also by the occurrence of several lenses of conglomerate, 
 of which the most 'miwrtant is that of Shoal lake. To the south of 
 the quartzites and slates are the mica schists of the Coutchiching 
 series. The relations of the Seine and Coutchiching series will not 
 here be discussed. 
 
 It was my expectation in following the basal conglomerates of 
 the Seine series eastward, that they would prove to be the same as 
 one of the conglomerates described by Smyth on .Steeprock lake. 
 This exi)ectaticn was, however, not realized. The boundary line 
 between the Keewatin and the Seine series was followed with a 
 steady E.-W. strike along the Atikokan river aa far as the iron mines 
 east of Sabawe lake. The east and west strike of the base of the 
 Seine series is transverse to the more nearly N.W.-S E. folds, which 
 have involved the Steeprock series in vertical attitudes a little to 
 the north of the Atikokan river. This stratigraphic and structural 
 relationship indicates that the folding which involved the Steep- 
 rock series as a sharp trough sunk down into the older Archsan 
 had taken place anterior to the deposition of the Seine series; since 
 no such folding affects the even trend of the strike of the latter. 
 It is, therefore, inferred tentatively that the Steeprock series is 
 older than the Seine series, an inference which should be confirmed 
 by a careful search in the conglomerates of the Atikokan river for 
 lobbies of the Steeprock series. To the south of Sabawe lake the 
 Seine series is cut by the granite gneiss which forms so large a 
 <'eature of the geology of the Seine River and Shebandowan sheets, 
 '''he phenomena of intrusion and the metamorphism of the Seine 
 series consequent upon the intrusion are splendidly exemplified. 
 No one who is at all familiar with the ecology of the Thunder Bay 
 district will question .the unconformable superposition of the 
 Animikie upon the complex of which this granite gneiss forms a

 Tlip position of the Steeprock series, well ilowii in the 
 
 Areluean. is of interest from ii general |M)int of view, since, as will 
 
 appear in the se<iuel, the limestone of which it is chiofl.v composed 
 
 is fossiliferous. The fossils appear to 1m" the oldest forms of life as 
 
 yet discovered. 
 
 Before proeeedinfr with the statement 'f the ibservations which 
 necessitate a change in the interpretation of the geology- of Steep- 
 rock lake, it ina.v Im- saitl that the exposure of the rocks nl)OUt the 
 lake is probably much better than it was at the time of Sm.vth's 
 visit in ISiM. The region has Imhmi extensively, and in places very 
 thoroughly denu<led of its forests by fires, so that one may walk 
 inland from the shores of the lake at inan.v localities over bare 
 glaciate<l rock surfaces. Smyth's observations were confine<l to the 
 shores of the lake, and liis niappeil distribution of the formations 
 away from there was conjectural, as was genera'ly the case with 
 n'.aps made at that period in the Archwan terranes of western 
 Ontario. His observations as to tlie extent and distribution of the 
 two most important niemtH>rs of the Steeprock series: T, the basal 
 conglomerate, and. II. the limestone about the shores of the lake, 
 appear to have been most careful and accurate. The only modifica- 
 tion which I was able to make in his mapping of tlu^e formations 
 on the actual shore line was the extension of the conglomerate (I) 
 to the n' n shore on the northeast side of Northwest bay. I also 
 found ii '.ence of the fault which he places through Birch point. 
 
 Inla. .rom the lake shore, however, I found the distribution 
 of the rocks in certain localities, which are decisive for the inter- 
 pretation of the structure, to be otherwise than Smyth had con- 
 
 16279-.1

 jectured. This is notably the case, for example, in regard to his 
 formation IX — described as a dark grey clay slate. An east and 
 west section across the peninsula which terminates in Jackpine 
 point, made from the shore about three-fourths of a mile south of 
 that point, showed clearly that no such formation exists as mapped. 
 The rocks i.. the area mapped as clay slate are coarse agglomerate 
 schists, c"t by great dykes of greenstone. The surface here is 
 particularly open and well exposed, and one may walk freely over 
 the bare rocka. The supposed clay slates which crop out on the 
 shore at Smyth's locality 81, appear to be a local fades of the 
 agglomerate formation particularly well sheared, and having a very 
 limited distribution a and close to the shore, and grading into the 
 agglomerate. Formation IX, as distinct from VllI, appears, there- 
 fore, to be non-existent; and the syncline which is based upon the 
 supposed distribution of clay slate and agglomerate can no longer 
 claim recognition. 
 
 The agglomerate VIII, and the belt of greenstones and green- 
 stone schists VII — which lies to the east of it — are typical Kee- 
 watin formations, indistinguishable from and continuous with the 
 belt of Keewatin rocks of the north side of the Seine river which 
 has been traced through from Bainy Ickc. Tc the east of the belt of 
 greenstones and greenstone schists VII, is a narrow belt of con- 
 glomerate — Smyth's ' Upper conglomerate ' VI. This conglomer- 
 ate was conjecturally, but approximately correctly, mapped by 
 Smyth. I have confirmed his mapping by tracing the conglomerate 
 through from its outcrop on the end of the peninsula west of East 
 bay to the south end of Straw Hat lake. This lake was evidently 
 unknown to Smyth, although the exposures on its shores are of the 
 utmost importance for the interpretation of the stmcture. It lies 
 parallel to East bay, two-fifths of a mile west of its south end. The 
 course of the conglomerate belt for the distance indicated is parallel 
 to that of Smyth's conglomerate I, on the east side of East bay. 
 East of the conglomerate is a limestone, which occupies for the 
 most part a depression extending through from Falls bay to the 
 south end of Straw Hat lake. Thp 'imestone is exposed at both ends 
 of Straw Hat lake, and is identicui in character with the limestone 
 on the east side of East bay, Smyth's formation II. It evidently 
 underlies the waters of the lake. Between the north end of Straw 
 Hat lake and Falls bey it is exposed at intervals, and numerous 
 blocks of it occur in the depression. The depression ends in a little

 bay where a suiall creek flows into Falls bay. To the west of the 
 creek is a carbonated green schist lying against the conglomerate. 
 This is Smyth's formation V — ^the ' Upper calcareous green schist.' 
 This is probably a local impure facies of the limestone or detrital 
 material that has been carbonated by reason of its proximity to the 
 limestone. 
 
 On a small island on the east side of Straw Hat lake the rock 
 consists of a comparatively little altered -volcanic ash which is 
 identical with Smyth's formation III on the west side of East bay 
 of Steeprock lake, which he refers to as a 'ferruginous formation,' 
 but describes as an impure volcanic ash. It is a soft rock, prone to 
 disintegration, and like the limestone, lies chiefly beneath the waters 
 of Straw Hat lake and in the depression which extends through 
 from Straw Hat lake to Falls bay. Between these two occurrences 
 of the volcanic ash, the one on East bay and the other on Straw Hat 
 lake, lies Smyth's formation IV, 'Interbedded Cryatalline traps.' 
 This I found to consist very largely of rather massive green schists 
 of detrital origin, with abundant angular fragments of quartz, 
 traversed parallel to the strike by what appeared to be great dykes 
 of diabase, but which may possibly be massive flows. 
 
 On the east side of East bay the formations are as Smyth 
 described and mapped them, viz.: a basal conglomerate, I, of quite 
 moderate thickness, resting on the granite gneiss of the east shore, 
 followed to the west by bedded limestone, II, for a thickness of 
 several hundred feet, the whole in nearly vertical attitudes. 
 
 From the facts above stated, it is evident that in a section 
 transverse to East bay and Straw Hat lake we have to deal with a 
 twofold repetition of the same set of beds; and the unavoidable 
 conclusion is that the structure is a simple, closely folded syncline. 
 The three lowest formations of the Steeprock series as descvibed 
 by Smyth on East bay are repeated on Straw Hat lake in reverse 
 order. The duplication of formation IV has not been made out, 
 a'' it is doubtful if it can be, owing to the character of the rocks, 
 \i !h renders it difficult to distinguish one horizon from another, 
 ai. i to the dykes which cut it. The conglomerate VI is, therefore, 
 the same as I, and it is a basal conglomerate resting upon the 
 Keewatin. This conglomerate was deposited upon an eroded surface 
 across the contact of the Keewatin and the granite gneiss. The 
 insunken syncline happens to cover the contact, so that on one limb

 on the other limb, u)ion the Keewntin. 
 
 This interpretation of the Htriu-tiire (jrently »iiiiplitiei« tlio gcolofry 
 ut' SteepriH-k hike. The Steeproek serie* is rnliK'til to four fonnii- 
 tions, viz.: Siii.vth's 1, II, III, an<l IV. Formation V i* itientified 
 with II, uikI VI witli I. Forniatiiins VII anil VIII are Keewatin 
 lielow the biisal ••oii({lonu'rHt«'. nn<l IX is non-cvistent ih mapped. 
 
 With refertMiee to the d.vkes whieh traverse the retrioii, it may he 
 said that the (frecnstone pebbles in the basal i-Drigtomerate, whieh 
 Sniytli supposed to have been deriv(v| from mi earlier system of 
 dykes, are derive*! from the Keewatin, and that ni-nrly all the dykes 
 belonjr to his second chiss, i.e., are later than the SttK-proek series. 
 
 A word in regard to the Atikokan series also may not Ir' out of 
 plaee. I e.\aniine<l, very cursorily, the shores of Margaret lake, and 
 found no reason to segregate the rooks there exiwscd fron: those of 
 the basement iiiion whieh the Steeproek series rests. .Mr. Smyth 
 regarils these rocks as of later age than the Steeproek series lying 
 across the edges of the latter. It seemed to me that following the 
 Steeproek formations southerly along their strike they abutted 
 upon the rocks of Margaret lake by reason of a X.E.-S.W. fault with 
 resultant down-tiirow on the N.W. side; the formations of the Steep- 
 roek series having been entirely removed on the south side. 
 
 The simplification of the structure, and the rttluction of the 
 number of its constituent formations detracts nothinjr. however, 
 from the interest attaching to the Steeproek series. There is 
 enough of it left to make it a most important n;cmber of the 
 Archiean Comple.x. The fact that it is definitely segregated from 
 the Keewatin, only adds to the interest. But perha|)s the most 
 interesting fact connected with this series is that its dominant 
 formation, the limestone, which is estimated by Smyth to be not less 
 than 500 feet, nor more than 700 feet in thickness, is fossiliferous. 
 The rock is, in part, almost an aggregate of fossils, but, in part, it 
 is also composed of calcareous detritus derived from the waste of 
 organisms, as iuay be clearly determined from the cross-be<lded 
 structures which are quite apparent in it. 
 
 In part the fossils are wholly calcareous, and in part they are 
 wholly silicified, and there are intermediate conditions due to partial 
 silicification. Where not silicified the fossils api)ear on the 
 weathered surface of the limestone as radial structures, the rays 
 extending out to a limit which is approximately circular in sections

 normal to the asi* of the organirau. In oblique nei^tions the peri- 
 phery may be more or less elliptical. The diameter of these circular 
 Itoundaries varie* in the hundreds of specimeiui obwrve«l, from about 
 
 I inch to about 15 inches. This variation in siie is probably due 
 partly to differences in the stage of development of the organism, 
 iind partly to the position of the random section of the surface of 
 the limestone exi»osing the form. For when viewol in three dimcn- 
 '•ioM and not merely in !«-«-tion, some of these fossils appear to liiive 
 
 II tapering and more or less curve*! or cornucopia shaix". The radial 
 structure is due to the presence of rays whi<-h diverge from the axis 
 of the cornucopia. Occasionally, it may be obs<>rve<l that these are 
 iuternipte<l by one or more cylindrical or conical septa concentric 
 with the axis of the rarnucopia, but in most cases no such concen- 
 tric septa Clin l>e detected In other cases, particularly in regard to 
 the larger fonns, it cannot be observed that they are cornucopia 
 'ihaped, ami the riiys u)>iH'ar to radiate in all direi'tions from a 
 centre. 
 
 Often tliese fossils arc so crowded toKcthcr that they abut one 
 against another; but in no case are tJie individual rays observed to 
 cross. In the larger forms the limits of the radial structure are much 
 less definite than in the case of the smaller cornucopia shaped forms, 
 and on the weathered surface the rays appear to fade away into the 
 Keneral matrix of limestone. The clearly apparent structure is. 
 however, contained within u circular area on the surface of the 
 rock. 
 
 Where these forms have been silicitied they c(uiimonly project 
 liroiniiiently above the surface of the limestone, and the structure 
 can be more easily observed. In these silicified forms the rays and 
 the tapering or cornucopia shaiie are commonly apparent. It is 
 evident from the sudden passage from conglomeratr to limestone 
 and from the cross-bedded character of some of the limestone, that 
 the organisms which contributed their remains to the building up 
 of this important formation thrive<l in shallow water, and that the 
 accumulation of their structures gave rise to some sort of a fringing 
 reef along the shore, which from time to time was reduced by the 
 waves to a calcareous sand which was scoure<l by the currents. 
 
 The fossils collected were submitted for study to the lion, 
 t.'harles D. Walcott. the eminent authority on the earliest fonr.s of 
 life, and he liiis very kindly supplio<l the descriptive notes which

 Oharlts D. Waloott. 
 
 Through tho courtesy of Dr. Amlrcw C. Lawson, I liavo hod the 
 opportunity of studying eomo orgaiiii; remains occurring in tho 
 Steeprock scries of Btceprock lake, northweit of Atikokan, on the 
 Canadian Northern railway, west of Port Artliur, Ontario, Canada.* 
 
 Mr. II. L. Smyth concluded from his studies that the Steep- 
 rock series rested unconformably upon a basement complex, and 
 Van Ilise and I«ith, in their gr ut memoir on the Geology of the 
 Lake Superior Keftion, have include<l the Steeprock series fif Smyth 
 in the lower Iluronian.' 
 
 Tiie Steeprock Lake region was studied by Dr. Lnwson during 
 the season of 1911, who found in the lower limestone above the 
 conglomerate of the Steeprock scries tho remains of fossils des- 
 cribed in these notes; and from his field observations placed the 
 Steeprock series above an erosion interval beneath which occurs 
 the Keewatin of the ArcluDan. 
 
 After a preliminary study of the material, I was incline<l to the 
 view that the remains indicated the presence of the Arch/ro- 
 ciiatliiniii' of the lower Cambrian; but after making thin sections 
 and tieating the silicified specimens with acid, I decided that they

 cavity, an outer and inner wall with radiating tubes connecting 
 them; the tube walls are perforate in Hyrinyocnema. and thoy 
 appear to be so in Adk-okania. The presence of irregular lepta in 
 Atikokania served to distinguiith the genus from Syvingoenema, and 
 to caiiao a comparison to be made with irr<>gulurly septate genera of 
 the ArchaocyalhiiuB, such as Pycnoidocyathu* Taylor (PI. XII.
