Pressure-temperature-reaction history of metapelitic rocks from the Maryland Piedmont on the basis of correlated garnet zoning and plagioclase-inclusion composition
Pressure-temperature-reaction history metapelitic rocks Maryland Piedmont garnet zoning plagioclase-inclusion composition
2012/4/9
Regional structural interpretation, thermobarometry, and Gibbs-method calculations werecombined to determine an approximate P-Tpath for kyanite-grade metapelitic rocks ofthe Baltimore Gneiss terrane. ...
Magma evolution recorded in plagioclase zoning in 1991 Pinatubo eruption products
Magma evolution plagioclase zoning Pinatubo eruption products
2012/4/6
Plagioclase, the mostabundant phenocryst at MountPinatubo, displays varying textures and compositions within the 1991 eruption products. In June 7-14 dome-forming ande-site, plagioclase phenocrysts sh...

Abstract: Analytical and high-resolution transmission electron microscopy of weathered plagioclase and K-feldspar provided microtextural and chemical data that suggest a sequential formation of weathe...
Scanning Electron Microscopic Study of Imogolite Formation from Plagioclase
Alteration Fiber Imogolite Plagioclase SEM Weathering
2012/2/9
Imogolite occurs as tiny bumps less than 0.05 祄 in diameter and about 0.3 祄 long on amorphous thin layers on the surface of weathered plagioclase. The bumps grow outward from the surface to form proje...
