Thermal Metamorphism of CM Carbonaceous Chondrites: Effects on Phyllosilicate Mineralogy and Presolar Grain Abundances
Abstract
Thermal metamorphism of CM chondrites results in phyllosilicate decomposition, presolar grain destruction, and radiogenic noble gas depletion. The depletion of 129Xe and 40Ar suggests that heating occurred later in the meteorite history.
