Thermally metamorphosed CM chondritic clasts reveal deep interior conditions: Insights from thermometry

We studied four coarse-grained crystalline clasts within CM carbonaceous chondrites to constrain their thermal history and origin. These clasts have near-identical mineralogies, dominated by olivine (Fa 37 or Fa 40 ), with lesser quantities of high-Ca pyroxene (diopside: Fs 10-11...
