CRISM: Hydrated minerals of Cydonia Colles

In this scene we observe the knobs within the northern lowlands (Acidalia Planitia) that are Fe/Mg phyllosilicate-bearing (pink-blue) and small, patchy exposures of hydrated silica (green) surrounding the knobs. Previously, phyllosilicates have only been found within impact craters in the … Continue reading
