Thermobarometry of the Bleikvassli Zn-Pb-(Cu) deposit, Nordland, Norway

Mineralium Deposita, 1998
The Bleikvassli massive sulfide ore deposit is hosted by Proterozoic pelitic, quartzofeldspathic, and amphibolitic rocks of the Uppermost Allochthon of the Scandinavian Caledonides. Staurolite-garnet-biotite and kyanite-staurolite-biotite assemblages indicate that metamorphism reached the kyanite zone of the amphibolite facies.

Relative thermobarometry and metamorphic P-T, paths

Geological Society, London, Special Publications, 1989
Summary Relative thermobarometry involves the determination of changes in P and T experienced by a rock through analysis of mineral zoning, inclusion suites and reaction textures. For this purpose, the differential forms of the thermodynamic equations and mass balance constraints ...

Magma transport at Hawaii: Inferences based on igneous thermobarometry

Geology, 1997
Pyroxene + liquid equilibrium in Hawaiian lavas occurs at a range of pressures for each volcano. Ranges are systematic and may be related to the stage of development of the magma conduit system. Kilauea, which is in its shield-building phase, yields relatively shallow storage estimates.

WinPyrox: A Windows program for pyroxene calculation classification and thermobarometry

American Mineralogist, 2013
A Microsoft Visual Basic program, called WinPyrox, has been developed to calculate structural formulas of both wet-chemical and microprobe-derived pyroxene analyses. Based on the standard International Mineralogical Association (IMA-88) nomenclature scheme, WinPyrox primarily calculates and classifies pyroxene groups and then determines a specific ...

MagMaTaB: A machine learning-based model for magmatic liquid thermobarometry

Determining pressures and temperatures of magmas is crucial for addressing diverse challenges in petrology, geodynamics, and volcanology. However, inherent inaccuracies, especially in barometry, have limited the effectiveness of existing models in unravelling the architecture of crustal igneous systems.
