Elastic thermobarometry on metapelites and igneous rocks across the crustal section of the Famatinian Arc, Argentina. [PDF]

open access: yes
Determination of the pressures and temperatures at which rocks form is crucial to understanding petrologic processes in Earth. Elastic thermobarometry is a new, simple, technique that has shown early potential to accurately constrain the temperature and ...

An Analysis of an Appalachian Metamorphic Suite [PDF]

open access: yes, 2011
The Blue Ridge is one of over a dozen provinces located in the much larger Appalachian Mountain Range which spans across the eastern United States. The Appalachian Mountains began to form close to 500 million years ago and rocks within the Blue Ridge ...

The effect of water activity on calculated phase equilibria and garnet isopleth thermobarometry of granulites, with particular reference to Tongbai (east-central China)

open access: yes, 2014
Granulites form at low water activities whose exact value is often unknown. This complicates the calculation of equilibrium assemblage phase diagrams and metamorphic pressure (P) and temperature (T) conditions by isopleth thermobarometry, because the ...

Mineral Chemistry and Pressure and Temperature Estimates of Metasedimentary Rocks of the Araxá Group in the Region of Morrinhos, South of Goiás State [PDF]

open access: yesGeologia USP. Série Científica, 2011
In the Morrinhos region, Goiás state, Brazil, the rocks of the Araxá Group have mineral assemblages related to themetamorphic peak which occurred in this region and is typical of the amphibolite facies (kyanite zone).

Deciphering the pressure‒temperature path in low-grade metamorphic rocks by combining crystal chemistry, thermobarometry and thermodynamic modelling: an example in the Marguareis Massif (Western Ligurian Alps, Italy)

open access: yes
International audienceUnveiling the pressure‒temperature path of low-grade metamorphic rocks is challenging because ofthe occurrence of detrital minerals phases and high-variance mineral assemblages (i.e., chlorite–whitemica–quartz). This paper offers an
