Kuebler	Boron Isotope Signatures of Carbonatites: Novel Insights into Magmatic Carbonate Processes and Deep Mantle Carbon Flux	2021		.txt	text/plain	360	11	23	The total range (up to ~16‰) in δ11B values for carbonatites examined suggests either the presence of enriched recycled subducted material in their mantle source region, or reflects the interaction between continental lithosphere and upwelling asthenospheric mantle. A comprehensive B investigation of worldwide carbonatites ranging in age from 2.0 Ga to 40 Ma was conducted so as to provide insights into the origin and flux of deep mantle carbon within carbonatite melts over time.	cache/rb68x923z5d.txt	txt/rb68x923z5d.txt
