Comparative Spectroscopic Study of Three Ferric Sulfates: Kornelite, Lausenite
Introduction: Sulfates have been identified on Mars by orbital remote sensing (OMEGA and CRISM) and during surface exploration (Viking, MER) [1-4]. MER rovers have found Fe-sulfates at both landing sites. A ferric sulfate (jarosite) was identified with the Mössbauer spectrometer (MB) in Meridiani Planum outcrops (~10 wt.%) [5]. At Gusev Crater, light-toned salty soils are hydrous as seen by Min...
متن کاملFerric Sulfates on Mars: Mission Observations and Laboratory Investigations
Fe-sulfates on Mars: Sulfate is one of the major types of secondary minerals found on Mars by recent missions, which reinforced its importance for Mars science. Sulfates are excellent hosts of water, the sinks of acidity, and maybe the most active species in the past and current surface/near-surface processes on Mars [1]. Although Mgand Ca-sulfates were identified with wide vertical and horizon...

Introduction: Gypsum (CaSO 4 .2H 2 O) and bassanite (CaSO 4 .0.5H 2 O) were identified on Mars by OMEGA on Mars Express and CRISM on MRO [1, 2, 3]. An-hydrite (CaSO 4) is non-active in the spectral range of OMEGA and CRISM, but may also exist [4]. Ca-sulfate was inferred from compositional correlations revealed by APXS on Mars Exploration Rovers [5, 6, 7], but no definitive identification, as w...
