APG2: a New Version of APG, an Application for Amphibole-Plagioclase Geothermobarometry [PDF]
Journal of Sciences, Islamic Republic of Iran, 2016 APG2 is a computer application designed for amphibole-plagioclase geothermobarometry. It is the first updated version of APG and supports 4 thermometer models and 6 barometer models involving either amphibole-plagioclase or amphibole only. APG2 has capability to integrate all 4 thermometer models with 6 barometer models and produce 24 different states ...

Methods for Estimation of Uncertainties in Geothermobarometry
Advances in Intelligent and Soft Computing, 2012 The assignment of a realistic uncertainty in any measured and computed quantity is important in all physical sciences. The advent of large internally consistent thermodynamic data bases and the development of multi-reaction techniques for P-T estimates in metamorphic and igneous rocks have brought revolution in the field of geothermobarometry ...

The contribution of elastic geothermobarometry to the debate on HP versus UHP metamorphism. [PDF]
J Metamorph Geol, 2022 AbstractCharacterizing the pressure and temperature (P–T) histories of eclogite facies rocks is of key importance for unravelling subduction zone processes at all scales. Accurate P–T estimates provide constraints on tectonic and geochemical processes affecting subduction dynamics and help in interpreting the geophysical images of present‐day ...

EntraPT: An online platform for elastic geothermobarometry [PDF]
American Mineralogist, 2021 EntraPT is a web-based application for elastic geobarometry freely accessible at the "Fiorenzo Mazzi" experimental mineralogy lab website (http://www.mineralogylab.com/software/). It provides an easy-to-use tool to calculate the entrapment conditions of inclusions, with error propagation, from the residual strain measured in mineral inclusions. EntraPT

An Excel-based tool for evaluating and visualizing geothermobarometry data
Computers & Geosciences, 2013 Application of geothermobarometry based on equilibrium exchange of chemical components between two mineral phases in natural samples frequently leads to the dilemma of either: (1) relying on relatively few measurements where there is a high likelihood of equilibrium, or (2) using many analysis pairs, where a significant proportion may not be useful and

Thermoelastic properties of zircon: Implications for geothermobarometry
American Mineralogist, 2022 Abstract A thermal-pressure equation of state has been determined for zircon (ZrSiO4) that characterizes its thermoelastic behavior at metamorphic conditions. New pressure-volume (P-V) data from a “Mud Tank” zircon have been collected from 1 bar to 8.47(1) GPa using X-ray diffraction, and elastic moduli were measured from room ...

Clinopyroxene–Liquid Equilibria and Geothermobarometry in Natural and Experimental Tholeiites: the 2014–2015 Holuhraun Eruption, Iceland [PDF]
Journal of Petrology, 2019 Abstract Clinopyroxene–liquid geothermobarometry is a widely used tool for estimating the conditions under which mafic magmas are stored before they erupt. However, redox variability, sector zoning and disequilibrium crystallization present major challenges to the robust estimation of magma storage conditions.

Regional geothermobarometry in the granulite facies terrane of South India
Transactions of the Royal Society of Edinburgh: Earth Sciences, 1983 ABSTRACTIn 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?)

Garnet peridotites from Pohorje:Petrography, geothermobarometry and metamorphic evolution
Geologija, 2010 Ultrahigh-pressure (UHP) metamorphism has been recorded in Eo-Alpine garnet peridotites from the PohorjeMts., Slovenia, belonging to the Eastern Alps. The garnet peridotite bodies are found within serpentinized metaultrabasitesin the SE edge of Pohorje and are closely associated with UHP kyanite eclogites.
