Central aims of IODP Expedition 352 were to delineate and characterize the magmatic stratigraphy in the Bonin forearc to define key magmatic processes associated with subduction initiation and their potential links to ophiolites.

Single-pyroxene thermobarometry
Tectonophysics, 1980Abstract Enstatites in peridotites from the Vourinos ophiolites, Greece, have exceptionally high Cr/Al ratios, though the pyroxenes are in equilibrium with picotite. Phase-chemistry data yield new empirical relations for the critical effect of Cr on Al solubility, in full agreement with local Cr/Al ratio variations observed in some massifs. These new

A Windows program for pyroxene-liquid thermobarometry
Periodico di Mineralogia, 2018A Windows program (WinPLtb) has been developed to calculate wet–chemical and microprobe pyroxene analyses based on the standard International Mineralogical Association (IMA-88) nomenclature scheme. The program allows the user to enter clinopyroxene, orthopyroxene and associated composition of liquid or whole-rock and some calculated components in the

Thermodynamic Modeling and Thermobarometry of Metasomatized Rocks
2012Determining the P-T conditions at which metasomatism occurs provides insight into the physical conditions at which fluid-rock interaction occurs in the crust. However, application of thermodynamic modeling to metasomatized rocks is not without pitfalls.

Status of thermobarometry in granitic batholiths
Earth and Environmental Science Transactions of the Royal Society of Edinburgh, 1996ABSTRACT:Most granitic batholiths contain plutons which are composed of low-variance mineral assemblages amenable to quantification of the P– conditions that characterise emplacement. Some mineral thermometers, such as those based on two feldspars or two Fe–Ti oxides, commonly undergo subsolidus re-equilibration.

A comparative analysis of Raman shifts of quartz inclusions in garnet was made along two traverses across the Connecticut Valley Trough (CVT) in western New England, USA, to examine the regional trends of quartz inclusion in garnet (QuiG) Raman ...

Fluid Inclusion Thermobarometry as a Tracer for Magmatic Processes
Reviews in Mineralogy and Geochemistry, 2008Fluid inclusions in minerals may form in any type of volcanic or plutonic rock ranging from mafic to silicic compositions. Because all igneous rocks reach fluid saturation at some stage during their evolution, fluids trapped as inclusions in magmatic minerals belong to a certain paragenesis or phase assemblage, which may include minerals, melts and one

Orthopyroxene thermobarometry in simple and complex systems
Contributions to Mineralogy and Petrology, 1987In the system FeO-MgO-Al2O3-SiO2 (FMAS), the equilibrium Al-content of orthopyroxene coexisting with olivine and spinel was reversed in 18 experiments at 1 340° C and 11 or 18 kbar, using graphite capsules and PbO flux. In the CFMAS system (+CaO), the Al-contents of ortho- and clinopyroxene coexisting with olivine and spinel were reversed in 5 ...

WinAmptb: A Windows program for calcic amphibole thermobarometry
Periodico di Mineralogia, 2017WinAmtb is a Microsoft ® Visual Basic software developed for electron microprobe calcic amphibole analyses to calculate the pressure ( P ), temperature ( T ) and oxygen fugacity ( f O 2 ) conditions of amphibole-bearing alkaline to calc-alkaline rocks. The program estimates the structural formulae of calcic group amphibole analyses on the basis of IMA-
