History of Clays on Mars: How We Found Them and Why They are Important for Astrobiology
Detecting
clays on Mars has had a rocky history over the past 4 decades, but
detecting them on the surface today is becoming commonplace. This
presentation describes the instruments used for identification of clay
minerals, where we have found them, and what their presence means. Most
phyllosilicates require abundant liquid water to form and thus these
minerals provide important clues for the debate about whether Mars was
ever warm and wet or not. Also, some clay minerals are used for organic
reactions and they may have even been involved in the origin of life on
Earth.
