Abstract
DIFFUSION coefficients for the release of potassium from phlogophite and biotite in the range 1 to 50 × 10−10 cm2/sec have been reported by Rausell-Colom, Sweatman, Wells and Norrish1. Similar measurements have not yet been obtained for muscovite or its counterpart in soils, the fine grained materials generally referred to as illite.
