Mapping Global Lithospheric Mantle Pressure‐Temperature Conditions by Machine‐Learning Thermobarometry

open access: yesGeophysical Research Letters
Comprehending the temperature distribution within Earth's lithospheric mantle is of paramount importance for understanding the dynamics of Earth's interior.

Elastic thermobarometry of ultrahigh-pressure metapelites from the Brossasco-Isasca Unit (Dora-Maira Massif, Western Alps)

open access: yesLithos, 2023
We applied zircon-in-garnet (ZiG) and chemical thermobarometry to garnet-bearing metapelites from the ultrahigh-pressure (UHP) Brossasco-Isasca Unit in the Dora-Maira Massif (Western Alps, Italy).

Applications and Limitations of Elastic Thermobarometry: Insights From Elastic Modeling of Inclusion‐Host Pairs and Example Case Studies

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Elastic thermobarometry can be used to constrain the pressure and temperature conditions of mineral crystallization by exploiting the difference in the elastic evolution of a mineral inclusion and its host during cooling and decompression.

Elastic-thermobarometry: methods and applications to ultrahigh pressure metamorphic rocks

open access: yesPlinius, 2020
Ultra-High Pressure (UHP) metamorphic rocks represent the evidence we have for the detailed reconstruction of tectonic processes, which are the source of major natural hazards like deep-focus earthquakes and volcanic eruptions.

Mineral chemistry and thermobarometry of Eocene monzogabbroic stocks from the Bafra (Samsun) area in Turkey: implications for disequilibrium crystallization and emplacement conditions

open access: yesInternational Geology Review, 2014
Monzogabbro stocks including felsic enclaves (monzosyenite) around the Bafra (Samsun) area at the western edge of the Eastern Pontides cut Eocene-aged volcanic and sedimentary units.

Fluid Inclusion Thermobarometry as a Tracer for Magmatic Processes

open access: yesReviews in Mineralogy and Geochemistry, 2008
Fluid inclusions in minerals may form in any type of volcanic or plutonic rock ranging from mafic to silicic compositions. Because all igneous rocks reach fluid saturation at some stage during their evolution, fluids trapped as inclusions in magmatic ...

meltPT: A Python package for basaltic whole-rock thermobarometric analysis with application to Hawaiʻi

open access: yesVolcanica, 2023
Quantifying the depths and temperatures from which igneous rocks are derived is an important step in understanding volcanic, magmatic and mantle processes.

The Late- Cretaceous volcanic rocks from Talesh area (western Alborz): chemical variation, crystallization condition, hygrometry and tectonic setting [PDF]

open access: yesپترولوژی, 2020
In the Talesh area (western Alborz), a thick sedimentary- volcanic association formed in a littoral- deltaic environment during the Late Cretaceous. The extrusives comprise volcanoclastics (tuffs), lava flows (pillow and massive) and basic dykes.

Mantle and Crustal Xenoliths in a Tephriphonolite From La Palma (Canary Islands): Implications for Phonolite Formation at Oceanic Island Volcanoes

open access: yesFrontiers in Earth Science, 2022
The occurrence of mantle-derived peridotite xenoliths in phonolitic melts is a rare phenomenon, and is commonly ascribed to a mantle origin of the phonolite.

Geology and crystallization conditions of the Särkiniemi intrusion and related nickel-copper ore, central Finland – implications for depth of emplacement of 1.88 Ga nickel-bearing intrusions [PDF]

open access: yesBulletin of the Geological Society of Finland, 2020
Several Ni-Cu deposits occur within the Kotalahti area, central Finland, in proximity to an Archaean gneiss dome surrounded by a Palaeoproterozoic craton-margin supracrustal sequence comprising quartzites, limestones, calc-silicate rocks, black schists ...
