The mineralogy of Mars is the chemical composition of rocks and soil that encompass the surface of Mars. ... Phyllosilicates. Kaolinite (Al 2 Si 2 O 5 (OH) 4}
The composition of Mars covers the branch of the geology of Mars that describes the make-up of the planet Mars. " Hottah " rock outcrop on Mars – ancient streambed [ 1 ] [ 2 ] [ 3 ] viewed by the Curiosity Rover (September 12, 2012, white balanced ) ( raw , close-up , 3-D version ).
OMEGA has distinguished two types of phyllosilicates which are likely to be montmorillonite and nontronite based on known spectra. From OMEGA's perspective, Mawrth Vallis contains the highest abundance of phyllosilicates on Mars and has up to 65% of smectites in volume. [29]
Wislicenus crater contains layers, also called strata. Many places on Mars show rocks arranged in layers. Sometimes the layers are of different colors. Light-toned rocks on Mars have been associated with hydrated minerals like sulfates. The Mars rover Opportunity examined such layers close-up with several instruments. Some layers are probably ...
Phyllosilicates are sheet silicate minerals, formed by parallel sheets of silicate tetrahedra with Si 2 O 5 in a 2:5 ratio. Subcategories. This category has the ...
Another study also observed phyllosilicates to be closely located to chlorides with CRISM, as well as THEMIS. [5] Phyllosilicates also provide evidence for aqueous processes occurring during the Noachian period. [9] Both studies determined that the phyllosilicates were deposited first. [5] [8]
Nili Fossae is a group of large, concentric grabens on Mars, in the Syrtis Major quadrangle. They have been eroded and partly filled in by sediments and clay-rich ejecta from a nearby giant impact crater, the Isidis basin. [1] It is at approximately 22°N, 75°E, and has an elevation of −0.6 km (−0.37 mi).
Basalt has been identified on Mars in many places. Instruments on orbiting spacecraft have detected clay (also called phyllosilicates) in some layers. Scientists are excited about finding hydrated minerals such as sulfates and clays on Mars because they are usually formed in the presence of water. [4]
