Searching for "New" Dolomite with a Field Spectroradiometer

Stromatolites are structures built by the metabolic action of microbes. They are considered living fossils and in some locations, they are composed of dolomite. Dolomite is a calcium and magnesium carbonate. Dolomite that is not considered "ancient" is rare. Researchers are now looking for "new" dolomite that has been precipitated by microbial activity in lagoons. Identifying dolomite in the field is difficult. In addition to being rare, it can be mixed with calcite, magnesium calcite, and aragonite. Distinguishing dolomite from these similar minerals can be accomplished with a high resolution field spectroradiometer, like a PSR Series spectroradiometer from Spectral Evoluation.
