The Melt Program contains routines that help characterize volcanic rocks and also that calculate parameters needed to apply names based on chemical properties. This program calculates Thompson space components, names based on the Irvine and Barragar, and IUGS-Total Alkali versus Silica classifications, CIPW norms, and melt properties. The routines in the Melt Program will be needed to do the assignments associated with the first part of the Theory and Analysis section of the course.
