Thermometers and barometers for volcanic systems
KD Putirka - Reviews in mineralogy and geochemistry, 2008 - pubs.geoscienceworld.org
Knowledge of temperature and pressure, however qualitative, has been central to our views
of geology since at least the early 19th century. In 1822, for example, Charles Daubeny …

A new clinopyroxene-liquid barometer, and implications for magma storage pressures under Icelandic rift zones
DA Neave, KD Putirka - American Mineralogist, 2017 - degruyter.com
Pressure is one of the key variables that controls magmatic phase equilibria. However,
estimating magma storage pressures from erupted products can be challenging. Various …

Ambient and excess mantle temperatures, olivine thermometry, and active vs. passive upwelling
Mantle temperatures provide a key test of the mantle plume hypothesis, and olivine-liquid
equilibria provide perhaps the most certain means of estimating mantle temperatures. Here …

Igneous thermometers and barometers based on plagioclase+ liquid equilibria: Tests of some existing models and new calibrations
KD Putirka - American Mineralogist, 2005 - degruyter.com
Although many formulations of plagioclase+ liquid equilibria have been calibrated in the last
decade, few models specifically address the issue of temperature (T) prediction. Moreover …

Machine learning thermo‐barometry: Application to clinopyroxene‐bearing magmas
We introduce a new approach, based on machine learning, to estimate pre‐eruptive
temperatures and storage depths using clinopyroxene‐melt pairs and clinopyroxene‐only …

Mantle potential temperatures at Hawaii, Iceland, and the mid‐ocean ridge system, as inferred from olivine phenocrysts: Evidence for thermally driven mantle plumes
KD Putirka - Geochemistry, Geophysics, Geosystems, 2005 - Wiley Online Library
Temperature differences between lavas erupted at ocean islands and mid‐ocean ridges are
crucial to documenting the existence of mantle plumes. Olivines are useful for T estimation …

Effect of water on tholeiitic basalt phase equilibria: an experimental study under oxidizing conditions
ST Feig, J Koepke, JE Snow - Contributions to Mineralogy and Petrology, 2006 - Springer
To investigate the effect of water on phase relations and compositions in a basaltic system,
we performed crystallization experiments at pressures of 100, 200 and 500 MPa in a …
