Abstract

Methods of cleaning, segregating, and identifying minerals found in the coarse silt and sand fractions of soils are outlined. After a heavy liquid separation, identification was carried out mainly by the use of the petrographic microscope for the coarse silt and fine sand, and the binocular microscope for the medium and coarse sand. The Franz isodynamic separator, a staining technique for the identification of the potash feldspars, and index of refraction oils were also used. The distinguishing characteristics of about 35 minerals are described.
