We have detected a 30,000-square-kilometer area rich in olivine in the Nili Fossae region of Mars. Nili Fossae has been interpreted as a complex of grabens and fractures related to the formation of the Isidis impact basin. We propose that post-impact faulting of this area has exposed subsurface layers rich in olivine. Linear mixture analysis of Thermal Emission Spectrometer spectra shows surface exposures of 30% olivine, where the composition of the olivine ranges from Fo30 to Fo70. 

Evidence for extensive, olivine-rich bedrock on Mars

Color infrared observations of an area around the Nili Fossae acquired by the Mars Odyssey thermal emission imaging system have been used to map the regional distribution and geologic context of

An olivine cumulate outcrop on the floor of Jezero crater, Mars.

The geological units on the floor of Jezero crater, Mars, are part of a wider regional stratigraphy of olivine-rich rocks, which extends well beyond the crater. We investigate the petrology of

Extended surface exposures of granitoid compositions in Syrtis Major, Mars

The number of quartz and feldspar rich surfaces identified in northwestern Syrtis Major has been extended beyond previously reported results to a region of about 230 by 125 km. Thermal Emission

Mineralogy of the Nili Fossae region with OMEGA/Mars Express data: 1. Ancient impact melt in the Isidis Basin and implications for the transition from the Noachian to Hesperian

[1] The Nili Fossae region located on the northwestern quadrant of the Isidis Basin, Mars, displays superb exposures of bedrock outcrops that reveal mineralogy and composition of the crust. Previous

Olivine and Pyroxene Diversity in the Crust of Mars

Olivine- and HCP-rich regions are found in deposits that span the age range of geologic units, however, LCP- rich regions are find only in the ancient Noachian-aged units, which suggests that melts for these deposits were derived from a mantle depleted in aluminum and calcium.

Mineralogy of the Nili Fossae region with OMEGA/Mars Express data: 2. Aqueous alteration of the crust

[1] Nili Fossae is a region with fresh exposures of old material. OMEGA spectral data have revealed a strong diversity of minerals in the Nili Fossae region, including mafic minerals and

Ancient Australian Rocks and the Search for Life on Mars

We discuss the results of a remote sensing study that has revealed new details about an important rock unit dominated by two minerals that can be associated with volcanism (olivine) and life

Pretty Green Mineral--Pretty Dry Mars?

Spectra of the Martian surface from the Mars Global Surveyor Thermal Emission Spectrometer (TES) have been matched with laboratory spectra of olivine. Todd Hoefen and Roger Clark (U. S. Geological
