Recognized as the de facto technology for mineralogical analysis, the rugged portable TerraSpec mineral spectrometers...
For mining exploration geologists, these improvements translate into faster data capture at exploration targets and drilling sites. The improved data quality provided by the TerraSpec 4 Hi-Res mineral spectrometer also allows for accurate assessment of low-concentration and low-reflectance minerals, like iron-containing minerals such as serpentines and chlorites, which were previously difficult to measure.
