Presolar Grain Abundance Variation in the Miller Range 090019 CO3.1 Chondrite
Abstract
We determine a presolar O-rich grain abundance of 99ppm in MIL 090019 CO3.1. One matrix region has a low presolar O-rich grain abundance of 28ppm, indicating localized alteration. The presolar C-rich grain abundance (64ppm) did not vary with region.
