New Insights Into The Martian Crust And Angrite Parent Body Through Meteorites, Alison R. Santos

Earth and Planetary Sciences ETDs

Petrologic studies of two new, unique meteorites were conducted in order to characterize the samples and provide insights into their parent bodies. The first sample, Northwest Africa 7034, is the first martian meteorite breccia to be discovered. In an effort to understand the martian crustal materials sampled by the breccia, we developed a classification scheme for the breccia clasts based on their texture, mineralogy, and chemistry. We then further investigated two clast groups which contained trends in mineralogy and chemistry that suggested a possible genetic relationship between the two. Our findings suggest they are not related by a simple igneous …
