Plagioclase‐Saturated Melt Hygrothermobarometry and Plagioclase‐Melt Equilibria Using Machine Learning [PDF]
Geochemistry, Geophysics, GeosystemsCompositions of plagioclase‐melt pairs are commonly used to constrain temperatures (T), dissolved water contents (H2O) and pressures (P) of pre‐eruptive magma storage and transport.

Geochimica Et Cosmochimica Acta, 2017 Trace element partition coefficients between anorthitic plagioclase and basaltic melts (D) have been determined experimentally at 0.6 GPa and 1350–1400 °C in a lunar high-Ti picritic glass and a mid-ocean ridge basalt (MORB).

Hydrogen incorporation in plagioclase [PDF]
Geochimica et Cosmochimica Acta, 2020 We conducted experiments at high pressure (P) and temperature (T) to measure hydrogen solubility in plagioclase (Pl) with a range of compositions (An15 to An94). Experiments were run at 700-850 °C, 0.5 GPa, and f O 2 close to either the Ni-NiO (NNO) or iron-wüstite (IW) oxygen buffers.

IcarusPlagioclase is the most abundant mineral in lunar crustal rocks, and its elemental and Sr isotopic compositions vary among different lunar surface rock types, implying that plagioclase fragments in lunar regolith can be used to trace source-rock types ...

Micro-Textural Controls on Magma Rheology and Vulcanian Explosion Cyclicity
Frontiers in Earth Science, 2021 Understanding the relationship between degassing, crystallization processes and eruption style is a central goal in volcanology, in particular how these processes modulate the magnitude and timing of cyclical Vulcanian explosions in intermediate magmas ...

The Polumir granite: Addititional data on its origin [PDF]
Geološki Anali Balkanskoga Poluostrva, 2002 The Polumir granite is exposed on several localities due to erosion, and its chemical and mineral composition is presented in this paper. It is built of K-feldspar, plagioclase, myrmekite, metasomatic albite, biotite, muscovite and quartz, while apatite,
