The Martian Surface Composition
Space Science Reviews, 2001Mars is unique to have undergone all planetary evolutionary steps, without global resets, till its geological death: this is reflected in the variety of its surface features. The determination of Mars surface composition has thus the potential to identify the processes responsible for the entire Mars evolution, from geological timescales to seasonal ...

Mineralogy of the Martian Surface
Annual Review of Earth and Planetary Sciences, 2014The past fifteen years of orbital infrared spectroscopy and in situ exploration have led to a new understanding of the composition and history of Mars. Globally, Mars has a basaltic upper crust with regionally variable quantities of plagioclase, pyroxene, and olivine associated with distinctive terrains.

A model of Martian surface chemistry
Journal of Molecular Evolution, 1979Alkaline earth and alkali metal superoxides and peroxides, gamma-Fe2O3 and carbon suboxide polymer are proposed to be constituents of the Martian surface material. These reactive substances explain the water modified reactions and thermal behaviors of the Martian samples demonstrated by all of the Viking Biology Experiments.

The composition of the Martian surface
Icarus, 1964Abstract It is generally believed that the desert areas of Mars are composed of limonite. This model of the surface, while based upon polarimetric, spectrometric, color, and albedo measurements, contradicts a reasonable geologic model. An examination of the evidence for limonite on Mars shows that the above measurements are ambiguous.

The past four years have been particularly fruitful for Martian research as the enormous volumes of data collected during the Viking mission became readily available to the general science community, and as reformatting of the remote sensing data into cartographic products made the data more useable.

Computer generated surfaces have been created to aid in imaging, landing and rover studies for Mars and the moon. They are also being applied to the study of cratering histories. The surfaces are generated in steps which attempt to mimic geologic episodes.
