A New Unusual Bencubbinite (CBa), Sierra Gorda 013 with Unique V-Rich Sulfides

Abstract

The metal-rich (>20 vol% Fe,Ni-metal) carbonaceous chondrites include CH chondrites, CB chondrites [1] and the Isheyevo CH/CBb chondrite [2]. The CB chondrites are rare and divided into two subgroups based on their petrologic characteristics: CBa (e.g., Bencubbin, Weatherford, Gujba) and CBb (e.g., Hammadah al Hamra (HH) 237 and Queen Alexandra Range (QUE) 94411/94627) [1]. A recently described chondrite, Quebrada Chimborazo (QC) 001 is similar to CBa but unusual in containing shock melt and high pressure mineral phases [3]. Here we present preliminary results of study of unusual CB chondrite from Chile, Sierra Gorda (SG) 013, and describe V-rich sulfides which have not previously been found in the meteorite material.
