Using data from Mars Global Surveyor, Mars Odyssey and the Mars Reconnaissance Orbiter, scientists have found widespread deposits of chloride minerals. Some of these chloride deposits have been identified to be a mixture of anhydrous chloride salt and regional basaltic regolith. These are located in the southern highlands of Mars. [36]
Locations of chloride-bearing deposits (black) overlain on a Mars Orbiter Laser Altimeter (MOLA) elevation map (grayscale). Inset is of a region in Terra Sirenum investigated by Davila et al. (2011). Color represents elevation as determined by MOLA (red is higher elevation, yellow is lower elevation).
Based on chloride deposits and hydrated phyllosilicates, Alfonso Davila and others believe there is an ancient lakebed in Terra Sirenum that had an area of 30,000 km 2 and was 200 meters deep. Other evidence that supports this lake are normal and inverted channels like ones found in the Atacama Desert .
New images from NASA’s Mars Reconnaissance Orbiter may show where life first began on Mars. The site on southern Mars shows massive deposits in a basin that scientists say were formed a long ...
The composition of Mars covers the branch of the geology of Mars that describes the make-up of the planet Mars.

Abundant iron compounds are responsible for the bright brownish-red ...
Evidence of water from chloride deposits in Phaethontis quadrangle. Picture from HiRISE. Rocks on Mars have been found to frequently occur as layers, called strata, in many different places. Columbus Crater is one of many craters that contain layers. Rock can form layers in a variety of ways. Volcanoes, wind, or water can produce layers. [83]
A collection of Martian rocks could reveal details about potential past life on the Red Planet – but first NASA has to get them back to Earth.. For years, the U.S. space agency's Perseverance ...
