Mineral Mixtures

For the purpose of understanding how real rocks look when studied by Mössbauer spectroscopy, we are initiating the study of mixtures of mineral phases. Here we show mixtures of minerals that may be found on the surface of Mars (or other planets).

The photo to the left is representative of this mineral group; however, it is not the same sample on which spectra listed below were measured.

Mix 1 1:1 hematite to lepidocrocite
Mix 2 1:1 goethite to jarosite
Mix 3 2:1 ilmenite to hematite
Mix 4 2:1 magnetite to ferrihydrite
Mix 5 10:1 clinopyroxene to forsterite
Mix 6 1:1 orthopyroxene to fayalite
Mix 7 10:1 clinopyroxene to fayalite
Mix 8 1:10 clinopyroxene to fayalite
Mix 9 1:10 clinopyroxene to forsterite
Mix 10 1:1 clinopyroxene to enstatite
Mix 11 1:1 clinopyroxene to forsterite
Mix 12: 1:1 mixture of ferric sulfate and ferrous sulfate
Mix 13 1:1 mixture of synthetic Fo0 olivine and andradite standard garnet
