Crew 226 EVA Report 26-01-2022

EVA #: 7

Author: Maria Bustos, Felipe Torres

Purpose of EVA: Recognition of the lithology and geological description of the zone. Collection of clay samples.

Start time: 10:00 am
End time: 12:20 pm

Narrative: Several kinds of rocks were recognized, mostly sandstones and conglomerates. Also, ripples, wavy stratification, and other sedimentary structures were recognized. All the areas had a lot of signs of weathering, several kinds of regolith were also found, the most weathered formation was the one that contained the clays.

The clays did not show a clear stratification, and fresh clays were not so easy to find. At the end of the EVA, we found the clays in between the regolith. These clays were of white color and had some metallic minerals, we predict they may be pyrite, covelline, or chalcopyrite.

Further studies are necessary to continue analyzing the geology of the zone.
