Calibration, Validation and Evaluation of Machine Learning Thermobarometers in Metamorphic Petrology: An Application to Biotite and Outlook for Future Strategy

Journal of Metamorphic Geology, Volume 43, Issue 8, Page 755-780, October 2025.
ABSTRACT Geothermobarometry provides crucial constraints on the physical conditions of metamorphism, offering insights into petrogenetic processes and providing key information on thermal regimes and metamorphic depths to other geological disciplines.

Pohorje eclogites revisited: Evidence for ultrahigh-pressure metamorphic conditions

Geologija, 2010
Kyanite eclogites from the Pohorje Mountains, Slovenia, are providing the first evidence of ultrahigh-pressureEo-Alpine metamorphism in the Eastern Alps. Polycrystalline quartz inclusions in garnet, omphacite and kyaniteare surrounded by radial fractures

Integrating microstructure and geothermobarometry in deciphering complex tectonometamorphic histories: examples from the New England Appalachians, USA [PDF]

, 2010
The integration of geothermobarometry with microstructure has allowed a temporally constrained comparison and correlation of tectonothermal events across an orogen to a resolution and complexity not decipherable by traditional approaches. A succession of

Coupling Phase Equilibrium Modelling and Apatite‐in‐Garnet Elastic Barometry to Unravel the P–T Path of the Micaschist Unit From the Zicavo Metamorphic Complex (Corsica, France)

Journal of Metamorphic Geology, Volume 43, Issue 7, Page 681-705, September 2025.
ABSTRACT To gain insights into the pressure–temperature evolution of a scarcely studied portion of the Variscan basement of Corsica in southern Europe, we combined phase equilibrium modelling, Zr‐in‐rutile thermometry and apatite‐in‐garnet elastic barometry. We investigated Grt‐St micaschist rocks containing garnet grains of several millimetres in size

Raman scattering of omphacite at high pressure: toward its possible application to elastic geothermobarometry

Due to their widespread occurrence in several geological settings, omphacite inclusions could be used for elastic Raman geothermobarometry. However, the Raman scattering of complex silicate minerals entrapped in a host depends on both the chemical ...

Efficacy of Assessing Magmatic Storage Depth Using Natural Samples, Experiments and Thermodynamic Models: A Case Study From Valles Caldera, NM (USA)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Estimates of magmatic storage are typically made using mineral assemblages in natural samples, experiments and thermodynamic models (e.g., MELTS), where each method has limitations. Here, we compare each of these methods to assess their utility in estimating storage conditions for post‐collapse, two‐feldspar high‐silica rhyolites (HSRs ...

Characterizing Peridotite Xenoliths From Southern Vietnam: Insight Into the Underlying Lithospheric Mantle

Geochemistry, Geophysics, Geosystems, 2023
We present data for lithospheric mantle xenoliths sampled from two alkali basalts in south‐central Vietnam, Pleiku and Xuan Loc, including fertile spinel peridotites.

Numerical Modeling Integrated With Field Observations and Analytical Data of the 2021 Cumbre Vieja Eruption Improves Understanding of Eruption Dynamics at Mafic Volcanoes

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Abrupt transitions in eruptive style are common at mafic volcanoes, possibly leading to styles that potentially damage infrastructures and threaten the surrounding communities. During the 19th September–13th December 2021 Cumbre Vieja eruption (La Palma, Canary Islands), rapid changes in eruptive style were observed, from vigorous lava ...

Pyroxene chemistry of xenoliths related to volcanic rocks in the Eslamieh Peninsula (Saray volcano): Implications for geothermobarometry and tectonic setting [PDF]

علوم زمین خوارزمی, 2023
The high K-volcanic rocks of the Eslamieh Peninsula (Saray) are exposed in the northwestern Urumieh-Dokhtar magmatic belt. They mainly include phonolitic lavas and related xenoliths.
