Crew 202 – MartianMakers
Submitted by GEO Ellen Czaplinski
Analysis of mineralogy and regime of sand dunes and fluvial processes: The crew collected geological samples from six sites during their EVA near Kissing Camel Range. Samples included whole rocks, rocks separated from a larger parent body, and sand samples. Initial sample analysis consisted of classifying the rocks based on texture, grain size, sorting, and color using a hand lens and microscope. The samples were primarily sandstone, clays, shale, and sand from fluvial features like channels. Further analysis will need to be carried out in order to determine the mineralogy of the samples with the TREK portable spectrometer, and eventually compared to IR spectra of the samples taken in the lab.
