Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.Abstract High heat fluxes occurring in rift settings are expected to generate partially melted low‐pressure–high‐temperature granulites (LP–HTG). Therefore, studying these rocks can offer valuable insights into crustal reworking during extension. However, our interpretations are limited by the rarity of LP–HTG in the metamorphic record.

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

A Clockwise P-T Path from the Variscan Basement of the Tisza Unit, Pannonian Basin, Hungary [PDF]
, 1999 The polymetamorphic basement of the Tisza Unit forms a detached fragment of the Variscan European foreland of the Neotethyan realm. A clockwise evolution path of a gneiss-amphibolite complex of the Tisza Unit was reconstructed, investigating the ...

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.

Terra Nova, Volume 37, Issue 2, Page 111-118, April 2025.ABSTRACT The result of dating U–(Th)–Pb bearing minerals in metamorphic rocks frequently suffers from the interpretative relation of their growth to a specific metamorphic event. This problem occurs in the southern Pohorje Mountains. Therefore, granitic gneiss from this area was studied.
