Abstract

This project is analyzing spectroscopic remote sensing data of acidic dry lake environments as possible terrestrial analogs of acidic Martian brines and weathering processes. Lakes Chandler, Deborah, and Gilmore, located in Western Australia, are among the rare terrestrial examples of dry lakes hosting evaporite minerals, such as jarosite and alunite, indicative of acidic conditions. The three dry lakes were chosen for study because of differences in local bedrock geology, which is a primary factor affecting brine compositions and related ...
