A key reaction underlying the charge transport in iron containing oxides, clays, micas is the Fe 2 + - Fe 3 + exchange reaction between edge-sharing iron octahedra. These reactions facilitate conduction in these minerals by the thermally-activated ho

Biotite is the most frequent ferromagnesian phase in granitoids from the Malayer-Boroujerd Plutonic complex (MBPC), Zagros Orogen. The abundance of biotite decreases from granitoids towards dioritic intrusions, dioritic and gabbroic dykes to gabbroic

Granitic rocks surrounding Nasb-Zurar intrusion at North West Wadi Allaqi comprise two varieties: tonalite and granodiorite of older granite (OG), and monzogranite of younger affinity (YG). Plagioclase crystals in OG are generally zoned and range in

A new activity model for Fe–Mg–Al biotites is formulated, which extends that of Mg–Al biotites (Dachs and Benisek, Contrib Mineral Petrol 174:76, 2019) to the K2O–FeO–MgO–Al2O3–SiO2–H2O (KFMASH) system. It has the two composition vari

The new biotite activity model and standard-state thermodynamic properties of Ann, Phl, and Eas presented in part-I were used to make pseudosections of bulk compositions representing experimental Fe–Mg exchange equilibria and (model) pelitic bulk r
