Long-Range Order in Amphiboles

Reviews in Mineralogy and Geochemistry, 2007
Comprehensive knowledge of the order-disorder relations in amphiboles is essential to (1) complete understanding of the crystal chemistry of these minerals, and to (2) the use of amphiboles in thermodynamic calculations (e.g., of temperature and pressure of equilibration) where accurate activity models are critical to the accuracy of such treatments ...

Calcic amphibole equilibria and a new amphibole-plagioclase geothermometer

Contributions to Mineralogy and Petrology, 1990
There is currently a dearth of reliable thermobarometers for many hornblende and plagioclase-bearing rocks such as granitoids and amphibolites. A semi-empirical thermodynamic evaluation of the available experimental data on amphibole+plagioclase assemblages leads to a new thermometer based on the Aliv content of amphibole coexisting with plagioclase in

Amphibole compositional space

Mineralogical Magazine and Journal of the Mineralogical Society, 1966
SummaryThe basic formula of an amphibole is completely defined by stating the number of sodium atoms in X positions and the numbers of aluminium atoms in Y and Z. These three numbers are coordinates in a compositional space that can easily be represented.
