Morphom: a Fortran program for storage and analysis of shape measurements of sedimentary particles

Abstract

A computer program based on the method described in a previous paper (Gallart, 1981) stores and analyzes morphometric data for samples of up to 52 elements. After the input and updating of the data, Cailleux's, Kuenen's and Zingg's indices are computed by the program, and the results can be presented by listing spare samples, writing the half matrices of the equivalence probability among samples for every index, and plotting Tricart's or Zingg's modified diagrams which represent the sample mean values and the equivalence test for a selected probability. Some glacial, glaciofluvial and periglacial samples taken from the Pyrenees are shown as an example.
