Summary

This dataset contains descriptions and analytical data (i.e., electron microprobe, X-ray diffraction, spectral reflectance, and scanning electron microprobe analyses) for unexpanded and expanded vermiculite samples. These data are provided for 52 samples of vermiculite attic insulation, horticultural products, aggregate, and packing materials derived from mines near Enoree, South Carolina; Libby, Montana; Louisa, Virginia; Palabora, South Africa; and Jiangsu, China collected from 2000 to 2016. Electron probe microanalysis and spectra of unexpanded ores from these locations and Llano, Texas are also given. Tables of electron microprobe and spectral absorption information are also included along with ascii listings of spectral reflectance [...]

Purpose

Data were obtained to develop an in situ spectral technique to identify the provenance (e.g., source) for use by inspectors and laboratories for identifying potentially asbestos-bearing vermiculite insulation in buildings and homes.
