Aluminum in hornblende: an empirical igneous geobarometer.

American Mineralogist
By:  and 



Electron-microprobe analyses of hornblendes from five calc-alkaline plutonic complexes representing low- and high-pressure regimes define a tightly clustered linear trend in terms of total Al (AlT) and tetrahedral Al (Aliv) contents. Data collated from the literature on calcic amphiboles from other plutonic complexes and from phase equilibrium experiments using natural rocks or synthetic analogue compositions show a similar AlT-Aliv trend and systematic pressure effects.-J.A.Z.
