Geology Colloquium | Mapping Igneous Components in Vestan Regolith using GRaND data, Feb. 21

Andrew Beck

The Geological Sciences Colloquium series presents Dr. Andrew Beck discussing “Mapping Igneous Components in Vestan Regolith using GRaND data” on Friday, Feb. 21, at 2 p.m. in Clippinger 205.

Beck is an Assistant Professor at Marietta College in the Department of Petroleum Engineering and Geology.

Abstract: We compiled a robust HED meteorite geochemical dataset, resolving sampling size and petrologic issues.  A principle component analysis of nuclear remote sensing components from igneous components in that dataset generated an eigenvector matrix, which was then used to transform orbital nuclear data from the asteroid Vesta, a planetary embryo and the parent body of HED meteorites.  The resulting map is used to further constrain magmatic activity and igneous petrogenetic history on Vesta, and thus inform geologic processes early in the Solar System’s history.
