EVA leader: Michaela Musilova
Begin: 2:00pm
End: 15:55 pm
Type of EVA: Walking + ATV 350, ATV 350
Purpose: : Carbonate mineral prospecting and sampling, together with endolith prospecting and sampling
UTM Coordinates: UTM 12S 518231e 4250725n NAD27
Summary: We got to the same locations from Sol 1 EVA to make a better scientific documantation. This time we took GPS coordinates for each site and wrote all comments. We took several pictures of each outcrope and draw it in the notbook.
All the sampled sandstone outcrops are at the same level of stratigraphy in the Brushy Basing member of Morisson Formation and interpeted by Clarke & Stoker as anastomosing fixed fluvial channels.
The carbonates in the sandstones apear as concritions and cements and assumed to originated in latter diagenesys.
Michaela found another good outcrop for endolith samples and she collected some more from the site of EVA 1.
