- Impurities (13.3% wt.%) in the fraction < 2µm: 5.2% Quartz, 0.1% Plagioclase, 0.4% Calcite, 0.2% Dolomite, 1.3% Kaolinite, 0.2% Chlorites, 4.4% Clinopyroxenes, 1.4% Orthopyroxenes (Vogt et al. 2002). INFRARED SPECTROSCOPY: Typical spectrum for Wyoming bentonite with a moderateFe+3 content (band at 885 $cm^{-1}$). Quartz is detectable (band at 780, 800, 698, 400, and 373 $cm^{-1}$), a trace of carbonate (band at 1425 $cm^{-1}$).
