sample is a serpentine conglomerate in a carbonate matrix. A) False color image highlighting spectral diversity; polygons define the regions averaged for endmember spectra. B) Result of minimum distance supervised classification in ENVI. C) Averaged endmember spectra from (A), with USGS reference spectra. IDENTIFICATION AND QUANTIFICATION OF MINERAL(More)
Visible-shortwave infrared microimaging reflectance spectroscopy is a new technique to identify minerals, quantify abundances, and assess textural relationships at sub-millimetre scale without destructive sample preparation. Here we used a prototype instrument to image serpentinized igneous rocks and carbonate-rich travertine deposits to evaluate(More)
