Solvus thermometry involves phases that form a solid solution at high-T but that 'unmix' into separate phases during cooling. The composition of coexisting minerals that have a solvus …

1994年7月1日 · Six different thermodynamic models for ternary feldspar and one user-defined model are incorporated into this program for both solvus calculations and thermometry. An …

2020年5月1日 · Feldspar solvus thermometry can be a reliable indicator of the temperatures of crystallization of coexisting feldspars in pegmatites. Feldspars record nearly isothermal …

2019年11月29日 · Temperatures of crystallization for all or portions of three thin granitic pegmatite dikes in southern California are derived from feldspar solvus thermometry, with …

Examples of solvus thermometry are the two feldspar, two-pyroxene and calcite–dolomite thermometers. This corresponds to the popular magnetite–ilmenite geother-mometer. This …

8.2 Solvus thermometry Solvus thermometry is based on the distribution of a component between two coex-isting phases occurring on the limbs of a miscibility gap. The boundary of the gap, …

The program SOLVCALC is a user-friendly graphic interface software for calculating the ternary feldspar solvus and the equilibrium temperature of coexisting natural ternary feldspar pairs. …

1994年7月1日 · The usable temperature range of liquid crystal thermometry has been extended and used to measure three-dimensional temperature fields in turbulent thermal convection. …

Within this pressure range, the utility of Pg-Ms solvus thermometry is limited thermally to approximately 300 ≤ T ≤ 700° C by (1) the decomposition of K-saturated paragonite at …

1990年6月1日 · The coexisting AF and PF compositions produced as products define compositional fields that are elongate parallel to the ternary solvus. In 11 experiments reaction …
