The Logarithmic Spiral: Definition and Expression of a New Graphical Representation of Results in Sedimentological Analysis

Autor: Pierre Weydert

Publikováno v: SEPM Journal of Sedimentary Research. 46

To avoid the loss of information in the coarser and the smaller fraction, results of size analysis of sample can be plotted in three-component diagrams, also called ternary diagrams or triangular diagrams, the sample being represented by a single poi
