Intracrystal microtextures in alkali feldspars from fluid deficient felsic granulites: A chemical and TEM study

Popis výsledku v původním jazyce

Samples of essentially ?dry? high-pressure felsic granulites from the Bohemian Massif (Variscan belt of Central Europe) contain up to 2 mm large perthitic alkali feldspars with several generations of plagioclase precipitates in an orthoclase-rich host. The first generation takes the form of lenses homogeneous in size whereas the size of a second generation of very thin albite-rich precipitates is more variable with comparatively high aspect ratios. In the vicinity of large kyanite, garnet or quartz inclusions, the first generation of plagioclase precipitates is significantly less abundant, the microstructure is coarser than in the remainder of the perthitic grain, and the host is a tweed orthoclase. The first generation of precipitates formed at around850°C during the high pressure stage (16-18 kbar) of metamorphism. Primary exsolution was followed by primary coarsening of the plagioclase precipitates which still took place at high-temperatures (850-700 °C). The coarsening was pronoun
