WebFeb 1, 2005 · Biotite Ti-substitution mechanisms are controlled by several factors. Based on the biotite calibration data set, magnesian biotites (X Mg > 0.65) incorporate Ti in accordance with the exchange vector TiAl 2 R −1 Si −2, where R is the sum of the divalent cations Mg + Fe + Mn. This substitution mechanism is primarily a response to misfit of ... WebSep 5, 2024 · Biotite is a common rock-forming mineral in a variety of igneous rocks, and its chemical composition has been widely used to retrieve associated magma properties and magmatic processes. Temperature and pressure are the two most important intensive parameters of magmatic processes, but a reliable biotite-based thermobarometry is …
