Abstract:

An experimental technique is presented for the identification of the major mineral constituents in small samples of atmospheric particulates. Each sample is divided into two parts one is examined by x-ray powder diffraction at two wavelengths, copper and chromium K alpha, and the other is examined by infrared absorption. With this combination it has been possible to extend component crystalline mineral identification down to 1 mg of total sample. Author
