Geology of Mars
Similar to Earth, all of the planets, including Mars, are defined by geologic processes. Of course, these geologic processes and conditions differ among the planets depending on various factors, such as the relative distance to the sun, composition of the planet, vulnerability to impacts and collisions, etc. Of all the planets, Mars is the closest to Earth-like conditions (Head 1). On the surface of Mars, as well as all of the telluric planets, the most abundant minerals are silicates. On Mars, the origins of most of the silicates are of basaltic to andesitic basaltic. On its surface, the main ...
