Detecting carbonates on the martian surface
Was Mars warm and wet enough to support life during the planet’s first few hundred million years? Scars of ancient lakes and rivers, as well as minerals that form only when water is present, have convinced many researchers that Mars … Continue reading

CRISM: Iron-magnesium phyllosilicates near rim of Gale Crater
CRISM scene FRT0000B5A3 covers the southern wall of Gale crater, 15 km downslope from the rim. This region is gently sloping, compared to the northern wall, potentially indicating that the Gale basement rocks in the crater rim are mantled by … Continue reading

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

CRISM: Hydrated minerals in Chryse Planitia
The Chryse Planitia is a smooth circular plain that has a diameter of 1600 km, and has a depth of 2.5 km below its average surface altitude, making it one of Mars’s lowest regions. Chryse Planitia was a landing site … Continue reading
CRISM: Phyllosilicates near Syrtis Major
This image shows a site near Syrtis Major, an expansive volcanic structure. This CRISM image displays olivine-rich rocks in red and rocks rich in iron-magnesium- containing clay-like minerals called phyllosilicates in various other colors. Olivine is present in most places … Continue reading

CRISM: Fe/Mg phyllosilicates near Mawrth Vallis
This image shows iron/ magnesium-bearing hydrated minerals called phyllosilicates in a white/red color. Phyllosilicates are clay and clay-like minerals formed by chemical reactions with liquid water. They are very thin (microscopic) stacked layer crystal forms, also called sheet silicates. The … Continue reading

CRISM: Iron-magnesium clays at Isidis Basin rim
This image is located right along the rim of the Isidis impact basin, at the foot of Libya Montes. Here we see iron-magnesium phyllosilicates (cyan). Phyllosilicates are clay and clay-like minerals formed by chemical reactions with liquid water. They are … Continue reading
CRISM: Phyllosilicate minerals near Mawrth Vallis
This image, which covers a site located slightly west of the Mawrth Vallis outflow channel, shows aluminum-containing minerals called phyllosilicates in a cyan color and iron-magnesium-containing phyllosilicates in a red/magenta color. Phyllosilicates are clay and clay-like minerals formed by chemical … Continue reading

CRISM: Aluminum and iron/magnesium clays in Mawrth Vallis
This image, which covers a site located northeast of Oyama Crater, shows aluminum-containing minerals called phyllosilicates in a cyan color and iron-magnesium-containing phyllosilicates in a red/magenta color. Phyllosilicates are clay and clay-like minerals formed by chemical reactions with liquid water. … Continue reading
