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 ...
