Electrostatic energy for ion clustering in intermediate plagioclase feldspar

Electrostatic calculations estimated the energy of hypothetical ion clustering in intermediate plagioclase feldspars. The calculated energy appears too great to allow segregation of Ca and Na atoms into domains upon annealing without a corresponding movement of A1 and Si from an original disordered structure. The calculated energy may be sufficiently small that Ca and Na atoms can disorder part...

The Accuracy of Derived Plagioclase Compositions from Multi-component, Multi-phase Sand Mixtures: Implications for Determining Martian Plagioclase Compositions

Introduction. Plagioclase feldspar has been identified as the dominant mineral phase in the martian crust [1-2] through analysis of Mars Global Surveyor Thermal Emission Spectrometer (TES) data. Martian meteorites , samples of isolated terrain on Mars, contain plagioclase in abundances secondary only to pyroxene. Terrestrial basalts and andesites contain primary plagioclase that is calcic-inter...
