Science report
02/03/2013
Today we have media shoots but we did good science as well. We had an amazing discussion with Melissa about the inverted channel we studied yesterday. We tried to figure out the stratigraphy and the cement in the area (from Landsat we have bad resolution, but it seems we have carbonate cement…but we find potentially gypsum veins crossing cut the sandstone layer only. ) and the main line was how we could study this inverted channel bed…sedimentological studies with pictures and draws, Raman for the mineral composition (for concretion, for the veins)…isotopic analysis as well. Today we came back to make more pictures and good sampling. Yesterday, we took pictures with my camera (just from the half part of the channel), but the quality of pictures was not enough good so we repeated the photo shooting, and I had the chance to take a closer view on the outcrops. We had 3 good samples, 1 of the cemented part of the sandstone (with black concretions), 1 from the less cemented part of sandstone (also with concretions)…and I sampled concretion bearing sandstone from the debris (same layers are on the top of the outcrop). I would like to coming back to take more samples and observations.
Kind regards,
