Analysis Program for Distribution Density of Orientation Data

Abstract

In this paper, we presented the principle and the BASIC program for plots of orientation data, drawing contour of distribution density and clustering on the stereographic nets (the Schmidt's and the Wulff's net) . The principle of clustering is based on the Schaeben (1984) 's principle of hill climbing'procedure. The converted grid data are contoured on the screen of a personal computer using the subroutine *CONTOUR.
