Description

Scapolite is an important reservoir for volatiles in the deep crust and provides unique insights into the S isotope signatures at themantle/crust interface. Herewe document the first scapolite referencematerial (herein referred to as CB1) for in situ S isotope analysis. The chemical and isotopic composition of this euhedral, S-rich scapolite megacryst was characterized via LA-ICP-MS, EPMA, SIMS, and bulk fluorination gas source isotope ratio mass spectrometry. The CB1 scapolite is...[Show more]
