Descriptions and analytical data (electron microprobe, X-ray diffraction, spectral reflectance, and scanning electron microprobe analyses) for unexpanded and expanded vermiculite samples, a mineral product with commercial applications. Data are provided in CSV format. Descriptions of the samples are provided as PDF reports.

Spectra measured with laboratory, field, and airborne spectrometers. The instruments used cover wavelengths from the ultraviolet to the far infrared (0.2 to 200 microns). Laboratory samples of specific minerals, plants, chemical compounds, and man-made materials were measured. In many cases, samples were purified, so that unique spectral features of a material can be related to its chemical structure. Data are provided in text format as well as the SPECtrum Processing Routines (SPECPR) format.

Whole-rock major, minor, and trace element geochemical data for carbonatite samples from this deposit. Samples include a suite of outcrop samples and a suite of composite samples. Data are provided in CSV format.
