Abstract
TOURMAL is a user-friendly software package developed for editing, storing, calculating and plotting microprobe tourmaline analyses from different geologic environments such as granites and their related aplites and pegmatites, metasomatic and vein type ore deposits, stratabound base metal deposits, gold deposits, and sedimentary and metamorphic rocks. Calculated results, saved in comma delimited ASCII file format, permit the user to search for other applications related to tourmaline compositions. The program prepares 28 binary and seven ternary diagrams. It is written in Quickbasic for IBM PC and compatibles, and runs under DOS and Windows operating systems with a VGA graphic card. This program permits the user to convert standard binary graphs and ternary diagrams into PCX file format for high quality printouts.
