Get PriceAbstract Most sulfate minerals form only in specific pH conditions, making them useful markers of past environmental conditions on Mars. However, interpreting past environments requires a full understanding of the suite of minerals present, a task which is complicated by the fact that some minerals can spectrally mask others in the visible- to near-infrared (VNIR, 0.4-2.5 μm).

Get PriceIdentification of the cation nature from Raman spectra is quite difficult in this case. Nevertheless shifts on the low wavenumber region suggest the minerals were natro-jarosite. This result was confirmed by using LIBS and EDX techniques. Samples from Rio Tinto were also fully identified (Fig. 3-4).
