P23C:
Earth Analogues as Case Studies for Martian Geological Materials and Processes I


Session ID#: 10367

Session Description:
Over the last decade several steps have been made towards the reconstruction of Martian mineralogy, geochemistry, geomorphology and geology. In situ exploration by rovers, combined with remote sensing and analogue studies, has enabled significant advancement in our understanding of Martian chemistry and mineralogy. Terrestrial case studies play an important role in observing geological processes that may have taken place on Mars. This session includes analysis of sites that are consistent with current and former Martian environments, as well as sites that may replicate specific chemical or physical geologic processes that are thought to have taken place on Mars.

The present session aims to become a roundtable for Earth and planetary scientists studying terrestrial analogues as case studies of Martian geology at all scales. We especially welcome contributions from multidisciplinary approaches, combined field and Mars data analysis studies, and investigations using novel techniques.
