EMG (End Members Generator)
The application End-MembersGenerator (EMG) allows to establish, based on electronmicroprobe analyses (EMPA), the 19 end-members of thespinel group: MgAl2O4 (Spinel sensu stricto, s.s.), FeAl2O4(Hercynite), MnAl2O4 (Galaxite), ZnAl2O4 (Gahnite),MgFe2O4 (Magnesioferrite), Fe3O4 (Magnetite), MnFe2O4(Jacobsite), ZnFe2O4 (Franklinite), NiFe2O4 (Trevorite), MgCr2O4 (Magnesiochromite), FeCr2O4 (Chromite),MnCr2O4 (Manganochromite), ZnCr2O4 (Zincochromite),NiCr2O4 (Nichromite), MgV2O4 (Magnesiocoulsonite),FeV2O4 (Coulsonite), MnV2O4 (Vuorelainenite), Mg2TiO4(Qandilite) and Fe2TiO4 (Ulvöspinel).
EMG is an application that does not require an installation process and wascreated with the purpose of performing calculations toobtain: cation proportions (per formula unit, p.f.u.), endmembers of the spinel group, redistribution proportions forthe corresponding end-members in the Magnetite prism orUlvöspinel prism and a data validation section to check theresults.
EMG accepts .csv data files and the results obtainedcan be used to represent a given dataset with the SpinelVizprogram or any other 2D and/or 3D graph plotting software.
