Abstract
Relationship for the transformation of percentage values, plotted in a conventional regular tetrahedron, to 3-dimensional cartesian co-ordinates is derived to facilitate the calculation of statistical measures. Regression relationship is worked out using the recomputed values for six basalt compositions (data taken fromVemban, 1947) to numerically generalise the trend of crystallization.
