A Machine Learning-Based Approach to Clinopyroxene Thermobarometry: Model Optimization and Distribution for Use in Earth Sciences [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2022
Thermobarometry is a fundamental tool to quantitatively interrogate magma plumbing systems and broaden our appreciation of volcanic processes. Developments in random forest‐based machine learning lend themselves to a data‐driven approach to clinopyroxene

Elastic Thermobarometry [PDF]

open access: yesAnnual Review of Earth and Planetary Sciences, 2023
Upon exhumation and cooling, contrasting compressibilities and thermal expansivities induce differential strains (volume mismatches) between a host crystal and its inclusions. These strains can be quantified in situ using Raman spectroscopy or X-ray diffraction.

The Influence of Undercooling and Sector Zoning on Clinopyroxene–Melt Equilibrium and Thermobarometry [PDF]

open access: yesJournal of Petrology, 2023
Abstract Thermobarometry provides a critical means of assessing locations of magma storage and dynamics in the lead-up to volcanic eruptions and crustal growth. A common approach is to utilise minerals that have compositions sensitive to changes in pressure and/or temperature, such as clinopyroxene, which is ubiquitous in mafic to ...

THERMOBAROMETRY OF DEPLETED PERIDOTITES

open access: yesГеодинамика и тектонофизика
An assessment was made of the possibility of using olivine thermobarometry for xenoliths of depleted peridotites from the Udachnaya pipe (Yakutia), represented by 76 megacrystalline dunites and 5 megacrystalline harzburgites.

Eclogite thermobarometry: The consistency between conventional thermobarometry and forward phase‐equilibrium modelling

open access: yesJournal of Metamorphic Geology, 2023
AbstractEclogite thermobarometry is crucial for constraining the depths and temperatures to which oceanic and continental crust subduct. However, obtaining the pressure and temperature (P–T) conditions of eclogites is complex as they commonly display high‐variance mineral assemblages, and the mineral compositions only vary slightly with P–T.

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.

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 minerals belong to a certain paragenesis or phase assemblage, which may include minerals, melts and one

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.
