Growth of plagioclase rims around metastable kyanite during decompression of high-pressure felsic granulites (Bohemian Massif)
Samples of high-pressure felsic granulites from the Bohemian Massif (Variscan belt of Central Europe) characterized by a peak metamorphic (high-pressure) mineral assemblage of garnet?kyanite?plagioclase?K-feldspar?quartz ? biotite show well-...

Mineral textures of olivine minette and their significance for crystallization history of parental magma; an example from the Moldanubian Zone (the Bohemian Massif)
plagioclase and quartz. Accessory minerals are apatite, Cr-rich spinel and iron sulphides. Olivine is mostly replaced by talc and rimmed by two zones (coronas) - a talc-rich to the quartz rim and radially penetrates the qu...
