Jarosite and hematite at Meridiani Planum from Opportunity's Mössbauer spectrometer
Göstar Klingelhöfer,R. V. Morris,B. Bernhardt,Christian Schröder,Daniel Rodionov,P. A. de Souza,Albert S. Yen,Ralf Gellert,E. N. Evlanov,B. Zubkov,J. Foh,J. Foh,Uwe Bonnes,E. Kankeleit,Philipp Gütlich,D. W. Ming,Franz Renz,Thomas J. Wdowiak,Steven W. Squyres,Raymond E. Arvidson +19 more
TL;DR: Mössbauer spectra measured by the Opportunity rover revealed four mineralogical components in Meridiani Planum at Eagle crater: jarosite- and hematite-rich outcrop, hematITE-rich soil, olivine-bearing basaltic soil, and a pyroxene-bearing Basaltic rock (Bounce rock).

TL;DR: In this paper, the authors show that the surface enrichment is the result of a minor amount of transport and deposition by aqueous processes on the surface of olivine-bearing basalts.

TL;DR: Impure reworked evaporitic sandstones, preserved on Meridiani Planum, Mars, are mixtures of roughly equal amounts of altered siliciclastic debris, of basaltic provenance (40−±10% by mass), and chemical constituents, dominated by evaporitic minerals (jarosite, Mg, Ca-sulfates, chlorides, Fe-, Na-solves), hematite and possibly secondary silica (60−± 10%).

TL;DR: The Mars Exploration Rover Opportunity has investigated the landing site in Eagle crater and the nearby plains within Meridiani Planum, and the rocks are interpreted to be a mixture of chemical and siliciclastic sediments formed by episodic inundation by shallow surface water, followed by evaporation, exposure, and desiccation.
