Abstract: The formation of kaolin-group minerals in the weathering profile of granite, under the humid, temperate climate as found in Korea, was studied by X-ray diffraction (XRD), scanning electron m...
The Skiddaw Granite and its contact metamorphic aureole in the English Lake District provide an excellent opportunity to test the capability of the N-isotope system to trace devolatilization and larg...
Accessory monazite crystals in granites are commonly unstable during amphibolite fa-cies regional metamorphism and typically become mantled by newly formed apatite-allan-ite-epidote coronas. This dist...

The temperature and chemistry of hydrothermal fluids control the breakdown and for- mation of beryl in rocks of appropriate bulk composition. In rocks of the Triberg granitic complex in the Schwarzw...
Clay fractions separated from the A2, B, and C horizons of a soil formed on granite gneiss showed X-ray powder diffraction (XRD) spacings characteristic of trioctahedral illite. The trioctahedral illi...
Abstract: Laterite profiles developed from granite in southwestern Australia were studied by scanning electron microscopy. The morphology of soil materials reflects the mineralogy of secondary mineral...
Single grain X-ray and electron diffraction patterns of weathered biotite flakes exhibit groupings of 001 and hk reflections of biotite, vermiculite, mixed-layer clay minerals, and kaolinite indicatin...
Biotite in deeply weathered granitic rocks in southwestern Australia has altered to exfoliated grains composed of biotite, mixed-layer clay minerals, kaolinite, vermiculite, gibbsite, goethite, and he...
