THIN-SECTION ANALYSIS OF SANDSTONES ON WEIGHT-FREQUENCY BASIS.

The weight-frequency size distribution is generally accepted to be log-normal (phi-normal) for sandstones, but the nature of number-frequency distribution of particles in sandstones is largely unknown. This paper develops the theory of correction procedure for the observed weight-frequency moments obtained by thin-section analysis of sandstones (and clastic sediments in general) which was not available so far.
