Abstract: Halloysite and kaolinite coexist in anorthosite weathering profiles in the Sancheong district, Korea. X-ray diffraction (XRD) analysis on a transect of partially weathered anorthosites revea...

Regional structural interpretation, thermobarometry, and Gibbs-method calculations werecombined to determine an approximate P-Tpath for kyanite-grade metapelitic rocks ofthe Baltimore Gneiss terrane. ...
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...
Weathered perthite and mixed muscovite-kaolinite from a kaolinitic granite at Trial Hill in east Queensland and kaolinized sericitic alteration from a granite from the Ardlethan Tin Mine of New South ...
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...
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...
Plagioclase feldspar is one of the outermost minerals destroyed in the hydrothermal alteration of quartz monzonite of the Butte district, Montana. Single grains of andesine plagioclase showing varying...
