Genesis of the Tirschenreuth kaolin deposit in Germany …

The Cu and Li contents in the <2 µ m fractions of the Kohdachi kaolin samples are markedly higher than those at Tirschenreuth. From hydrogen isotopic analysis, the formation temperature of the Kohdachi kaolinite may be roughly estimated at 70–150°C. It is suggested that the Kohdachi deposit formed by hydrothermal alteration.

Ranong kaolin size fractions The Ranong sample was highly uniform in size and only two fractions (16À8 mm and 8À5 mm) could be separated from the untreated sample that was used in this work. Their EPR spectra were similar to those of the original kaolin (Fig. 1c), and consequently they will not be discussed further here. samples (Supplementary Fig. S6).

Kaolin is also known for its capabilities to induce and accelerate blood clotting. In April 2008 the US Naval Medical Research Institute announced the successful use of a kaolinite-derived aluminosilicate infusion in traditional gauze, known commercially as QuikClot Combat Gauze, [53] which is still the hemostat of choice for all branches of the US military.
