TL;DR: In this article, the location of red crystalline hematite within the uppermost stratum of an ∼6.5km-long ridge on the mound's northern flank was determined by using over-sampled Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) visible and near-infrared hyperspectral data.
Journal ArticleDOI
Implications for early hydrothermal environments on Mars through the spectral evidence for carbonation and chloritization reactions in the Nili Fossae region
TL;DR: In this article, the authors characterize Fe/Mg phyllosilicates associated with these units and present spectral evidence for the presence of a talc component, distinguishable from saponite.
Journal ArticleDOI
Olivine-Carbonate Mineralogy of the Jezero Crater Region
TL;DR: In this paper, the position and shape of the olivine 1 μm absorption band were mapped using the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) observations to characterize the surface mineralogy of the crater and surrounding watershed.
Journal ArticleDOI
Petrologic and textural diversity among the PCA 02 howardite group, one of the largest pieces of the Vestan surface
TL;DR: In this paper, howardites and two diogenites were recovered from the Pecora Escarpment Icefield (PCA) in 2002 and they constituted an approximately 1m (diameter) meteoroid prior to atmospheric entry.
Journal ArticleDOI
Challenges in detecting olivine on the surface of 4 Vesta
Andrew W. Beck,Timothy J. McCoy,Jessica M. Sunshine,C. E. Viviano,Catherine M. Corrigan,Takahiro Hiroi,R. G. Mayne +6 more
TL;DR: In this paper, the authors examined the visible/near-infrared spectra of two harzburgitic diogenites representative of the 10-30% olivine range and demonstrate that they are spectrally indistinguishable from orthopyroxenitic dogenites, the dominant diogenitic lithology in the HED group.
