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.

Science, 1966
With the scarcity of factual data and the difficulty of applying crucial tests, many of the properties of the Martian surface remain a mystery; the planet may become a source of great surprises in the future. In the following, the conclusions are enumerated more or less in the order of their reliability, the more certain ones first, conjectures or ...

Reviews of Geophysics, 1987
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.

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.

The morphology of the Martian surface
Space Science Reviews, 1980Most of the southern hemisphere of Mars is densely cratered and stands 1–3 km above the topographic datum. The northern hemisphere is more sparsely cratered and elevations are generally below the datum. A broad rise, the Tharsis bulge, centered at 14° S, 101° W, is 8000 km across and 10 km above the datum at its summit. The densely cratered terrain has
