Micaceous soils: methods of determining mica content and the use of routine tests in the evaluation of such soils

Abstract

This paper is in two parts, the first of which reviews several possible methods of determining the mica content of a soil and then describes in detail the development and successful operation of two methods, a vibratory method and a dielectric one. The second part of the paper records the results of standard laboratory tests on three soils with a high mica content and discusses the value and limitations of such tests in assessing the field performance of micaceous soils (A).
