Abstract
GRAPHIC ESTIMATIONS OF Φ VALUES IN GRAIN SIZE ANALYSIS OF ROCKS
Summary
Grain size analysis and representation of its results are of remarkable importance in geological studies. The methods of determination of value Φ, hitherto applied in the current practise, appear troublesome. The paper presents a new graphic metod of estimating the value Φ. This method involves the use of a nomogram, representing a modification of the function . expressed by the formula (3). The nomogram makes it possible to estimate values Φ with the accuracy ± 0.02 in size ranges from 256 to 0.0009 mm.
