Raman study of mineralogical precipitation sequence of Rio Tinto "Mars analog"
Abstract
Rio Tinto (Spain) has been proposed as potential Earth analog [1] for the geological and astrobiological exploration of Mars. In this context of Mars exploration, and considering the geomorphological and sedimentological features of the selected landing sites [2], an important point to consider is the ratios of mineralization/alteration due to hydration-dehydration processes. To carry out this objective a spectroscopic Raman study of a wide range of samples collected from Rio Tinto was performed. On the other hand it has carried out the simulation of the phenomenon of precipitation in the laboratory using small droplets of synthetic and natural water from Rio Tinto.
