# Spectroscopy Lab

Researchers at the USGS Spectroscopy Lab are studying and applying methods for identifying and mapping materials through spectroscopic remote sensing (called imaging spectroscopy, hyperspectral imaging,imaging spectrometry, ultraspectral imaging, etc), on the earth and throughout the solar system using laboratory, field, airborne and spacecraft spectrometers.

### USGS Digital Spectral Libraries

Reflectance spectra of minerals, mineral mixtures, rock coatings, liquids, frozen volatiles, organic compounds, manmade materials, vegetation, and other biological materials. You can download the main spectral library

VNIR-SWIR (400–2500 nm) reflectance measurements were made on the surfaces of various cores, cuttings and sample splits of sedimentary rocks from the Tertiary Jackson Group, and Catahoula, Oakville and Goliad Formations. These rocks vary in composition and texture from mudstone and claystone to sandstone and are known host rocks for roll front uranium occurrences in Karnes and Live Oak Counties, T
