Geochimica et Cosmochimica Acta, 2022 In ordinary chondrites (OCs), feldspar is present both in chondrules as a primary, igneous phase, and as a secondary phasethat results from crystallization of chondrule mesostasis glass during thermal metamorphism. To further understand thechemical and physical conditions prevailing during thermal metamorphism in OCs, we conducted a study of feldspar ...

Rubidium-rich feldspars and associated minerals from the Luolamäki pegmatite, Somero, Finland [PDF]
Bulletin of the Geological Society of Finland, 1998 Rubidium feldspar occurs near the core zone of the highly fractionated petalite-subtype Luolamäki granitic pegmatite in intimate intergrowth with other feldspars which are part of a characteristic sequence of alteration of pollucite.

Oxygen-isotope and trace element constraints on the origins of silica-rich melts in the subarc mantle [PDF]
, 2007 Peridotitic xenoliths in basaltic andesites from Batan island in the Luzon arc contain silica-rich (broadly dacitic) hydrous melt inclusions that were likely trapped when these rocks were within the upper mantle wedge underlying the arc.

Electron Microprobe Analysis of Biotite with Reequilibration Texture in Altered Trachyte
Yankuang ceshi, 2019 BACKGROUND The chemical composition of biotite contains important genetic information. The in-situ analyses of biotite with metasomatic texture can reflect the migration of the elements during the metasomatic alteration, and provide mineralogical ...
