A New Software Package for Rittmann Norm Calculation.

Abstract

MRittmann is a petrological software package for identifying and calculating the normative minerals of volcanic, sub-plutonic, and carbonatite rocks from bulks chemical analyzes. The calibration of the software is built on the Rittmann norm calculation principles, and its calculating results include both hydrous and anhydrous minerals, rock name as well as petrological index such as tau (τ) and degree of oxidation (Ox 0) of the analyzed samples. The norms obtained from MRittmann are in volume percentages. They are close to the ...
