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 ).
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 ...
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]
The mineralogy of Mars is the chemical composition of rocks and soil that encompass the surface of Mars. Various orbital crafts have used spectroscopic methods to identify the signature of some minerals .
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).
Phyllosilicates are sheet silicate minerals, formed by parallel sheets of silicate tetrahedra with Si 2 O 5 in a 2:5 ratio. Wikimedia Commons has media related to Phyllosilicates . Subcategories
Columbus is a crater in the Terra Sirenum of Mars. It is 119 km in diameter and was named after Christopher Columbus, Italian explorer (1451–1506). [1] [2] The discovery of sulfates and clay minerals in sediments within Columbus crater are strong evidence that a lake once existed in the crater.
On Mars, Bishop's research revealed these phyllosilicates are indicative of the presence of water. [7] In 2011, Bishop examined carbonate rocks in the Mojave Desert as an analogue for conditions that may occur on Mars [ 8 ] and her subsequent research revealed the wide-spread presence of rocks with carbonate on Mars [ 9 ] which could be ...
