On the basis of net transfer reactions among garnet, biotite, plagioclase and quartz (for both Mg Fe end-member models), garnet–biotite–plagioclase–quartz (GBPQ) geobarometer was empirically calibrated under physical conditions P = 1·0–11·4 kbar T 515–878°C, based on input garnet–biotite temperatures garnet–aluminosilicate–plagioclase–quartz (GASP) pressures 224 natural aluminosilicate-bearing metapelitic samples collated from literature. The calibrations are internally consistent with...

Abstract The garnet–biotite–muscovite–plagioclase (GBMP) barometer was empirically revised for P–T conditions of 1–14 kbar and 450–840 °C, using 263 metapelitic rock samples from all over the world. This is based on activity models garnet, biotite plagioclase identical to those well‐calibrated garnet–biotite thermometer garnet–aluminosilicate–plagioclase–quartz (GASP) barometer. GBMP less temperature dependent than GASP can be applied either Al 2 SiO 5 ‐absent or ‐bearing metapelites. total...
Garnet-bearing mafic granulite and amphibolite exposed as lenses, boudins, or interlayers within metasediments in the Qingshigou area, Dunhuang block, southernmost Central Asian orogenic belt, record important information for understanding tectono-metamorphic evolution of subduction collision zones southern belt during mid-Paleozoic. Three stages metamorphic assemblages (M1, M2, M3) are recognized high- medium-pressure amphibolite. In high-pressure granulite, prograde assemblage (M1) is...
In many metapelitic assemblages, plagioclase is either CaO-deficient or even absent. such cases, all the widely applied, well-calibrated plagioclase-related geobarometers lose their usage. Fortunately, it has been found that a net-transfer reaction including intracrystalline Fe2+–Ca2+ exchange in garnet pressure-sensitive, therefore, geobarometer can be empirically calibrated under pressure–temperature (P–T) conditions of 430~895 °C and 1~15 kbar. The chemical composition range calibrant XCa...
The garnet–muscovite (GM) geothermometer and the garnet–muscovite–plagioclase–quartz (GMPQ) geobarometer have been simultaneously calibrated under conditions of T = 450–760°C P 0·8–11·1 kbar, using a large number metapelitic samples in compositional ranges XFegrt 0·53–0·81, XMggrt 0·05–0·24, XCagrt 0·03–0·23 garnet, XCapl 0·17–0·74 plagioclase, Fe 0·04–0·16, Mg 0·04–0·13, AlVI 1·74–1·96 muscovite on basis 11 oxygens. resulting GM thermometer yielded similar temperature estimates (mostly...
Abstract High-resolution SIMS U–Pb dating of metamorphic zircons the TTG gneisses, gneissic granitoid and amphibolites Lushan terrane, Taihua complex, suggests that metamorphism had taken place at least as early ~1.96–1.86 Ga. These new dates, along with reference data, demonstrate southern middle terranes Trans-North China Orogen been involved in continent–continent collision between Western Block Eastern North Craton. This orogenic process started 1.96 Ga lasted late 1.80
Abstract A garnet–biotite–Al 2 SiO 5 –quartz ( GBAQ ) geobarometer was empirically calibrated using more than 700 natural metapelites with a broad compositional range of garnet and biotite under P–T conditions 450–950°C 1–17 kbar. In the calibration, activity models identical to those in garnet–biotite (GB) geothermometer Holdaway [ American Mineralogist 2000, 85: 881–892] were used. Therefore, GB can be simultaneously applied iteratively estimate metamorphic conditions. Successful...
