The Metamorphic Evolution of Matrix and Opaque Minerals in CO Chondrites
Abstract
We examined a suite of CO chondrites using large, 10-element X-ray maps. S changes dramatically between types 3.1 and 3.2, and migrates out of matrix. P and Cr are very mobile during metamorphism. Y-81020 is one of the most primitive COs.
