Mineral end-members and crystal chemistry calculations for SEM-EDS, EMPA or any mineral chemistry dataset.
Calculation based on the seminal book "An introduction to the rock-forming minerals" annex 1. The calculatios are based on the no of oxigens in the mineral formula- which works virtually with every mineral in the book.
The package is a simple wrap-up function of tidy- style operation to transform raw mineral chemistry from EPMA,SEM, LA-ICP to APFU values.
The data includes 3 mineral chemistry raw data from DHZ- garnet, tourmaline, and epidote- for benchmarkig (see vignette).
