SCG: A Computer Applicationfor Single Clinopyroxene Geothermobarometry
Italian Journal of Geosciences, 2014SCG stands for Single Clinopyroxene Geothermobarometry, a software application for clinopyroxene geothermobarometry introduced here for the first time to the scientific community along with an explanatory note. SCG is a highly specialised and user-friendly application.

Geothermobarometry of high-grade metapelites: simultaneously operating reactions
Geological Society, London, Special Publications, 1989Summary Experimental data on equilibria involving rock-forming minerals in high-grade metapelites (garnet, orthopyroxene, cordierite and plagioclase) have been used to derive an internally consistent system of mineralogical thermometers and barometers based on component reactions and excess mixing properties of solid solutions ...

Elastic geothermobarometry on multiple inclusions in a single host
2020<p>The characterization of the pressure and temperature (P-T) histories of subducted rocks is of key importance to unravel geological processes at all scales. Conventional element-exchange geothermobarometers are challenged in ultra-high-pressure metamorphic terranes as the subduction temperatures may exceed their closure ...

Metapelitic Garnet-Muscovite-Al2SiO5-Quartz (GMAQ) Geothermobarometry
Journal of Earth Science, 2018The garnet-muscovite geothermometer and garnet-muscovite-Al2SiO5-quartz (GMAQ) geobarometer have been empirically calibrated under P-T conditions of 1–12 kbar and 460–760 oC using natural metapelitic rocks. The chemical compositions of the calibrant muscovite are in the ranges of Fe=0.03–0.21 atoms, Mg=0.02–0.32 atoms and AlVI=1.62–1.96 atoms ...

Geothermobarometry of the Central Crystallines from the Garhwal Himalaya
Journal Geological Society of India, 1988Abstract Pelitic schists, gneisses and amphibolites from the Central Crystallines of the Garhwal Himalaya display evidence of multiple deformation (D1, D2 and D3) and polymetamorphism (M1, M2 and M3)' During the M1 episode of regional metamorphism which represents a thermal peak, the pelitic schists and gneisses developed the assemblage:

Regional geothermobarometry in the granulite facies terrane of South India
Transactions of the Royal Society of Edinburgh: Earth Sciences, 1983ABSTRACTIn the southern part of the Archaean craton of South India, an approximately 3.4–2.9 b.y. old migmatite–gneiss terrane (Peninsular gneiss complex) has been subjected to granulite facies metamorphism about 2.6 b.y. ago. During this event, the extensive charnockite-khondalite zone of southern India developed. A younger metamorphism (Proterozoic?)
