Abstract

METHOD OF GRAIN SIZE ANALYSIS OF FINE-GRAINED ROCKS BY MEANS OF COLORIMETER Summary The article presents a theory and describes the technique of measuring grain size of fine-grained rocks using the method of photoextinction. The method consists in measuring the intensity of the light that passes through the suspension of particles in a fluid, by means of standard colorimeter. Under proper measuring conditions the natural logarithm of intensity of transmitted light is a function of presence of the particles having a determined diameter. Basing on his own experiments and on the existing literature data, the present author discusses all merits and demerits of the method considered.
