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: The Moessbauer spectrometer on Spirit measured the oxidation state of Fe, identified Fe-bearing phases, and measured relative abundances of Fe among those phases for surface materials on the plains and in the Columbia Hills of Gusev crater as discussed by the authors.
