"Calcic Amphibole Equilibria and a New Amphibole-Plagioclase Geothermometer": reply to the comments of Hammarstrom and Zen, and Rutherford and Johnson
Article Abstract:
An analysis describing earlier research on amphibole geobarometry is presented. Earlier research questions the suitability of amphibole equilibria for geobarometry, amphibolic reluctance and silica activity effects on amphibole composition. Contrary to these findings, analysis shows that amphibole-plagioclase thermometers exhibit a barometric potential under controlled final equilibrium temperature conditions.

"Calcic Amphibole Equilibria and a New Amphibole-Plagioclase Geothermometer" - reply to the comment of Poli and Schmidt
Article Abstract:
An analysis describing earlier research on amphibole-plagioclase geothermometers. Earlier research assumes that the application of a single parameter, Al (super 4), to compositional variation indicates universality. Contrary to these findings, analysis shows that other substitutions are also considered by the thermometer model. However, Al substitutions do not exhibit any major impact on K (sub 1) expressions.
