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: Hydrated minerals near Nili Fossae
This image shows a site near Nili Fossae, a group of long, narrow tectonic depressions called graben. Mars’ crust is mostly made up of igneous rock and mafic materials, shown here with red denoting olivine. There are also aqueously-altered minerals … 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: Mafic minerals in Nili Fossae
The vast majority of the planet’s crust is unaltered igneous rock although there are some occurrences of aqueously altered rocks linked to past water activity. The colors here show concentrations of different minerals common in rocks that might tell us … 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

CRISM: Iron-magnesium phyllosilicates in Gale Crater
This image shows iron/magnesium-bearing hydrated minerals called phyllosilicates in pink. 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 CRISM team took … Continue reading

CRISM: Aluminum phyllosilicates in Mawrth Vallis
This image is located right along the dichotomy boundary within a drainage channel named Mawrth Vallis. Here we see aluminum phyllosilicates (cyan to blue) exposed on the rim of a crater. Phyllosilicates are clay and clay-like minerals formed by chemical … Continue reading
