Hyperspectral imagery of drill core allows the collection of SWIR spectral data at a spatial resolution similar to the sizes of many minerals. Mineral identification performed using a programming method based on positions and shapes of absorption features in characteristic SWIR spectral windows. Mineral maps created to highlight the structural features in the core samples, like bedding, veining, and regions of pervasive alteration.
