Pocket minerals from simple pegmatites and associated muscovite veins of Strážek Moldanubicum (Bohemian Massif, Czech Republic)

Simple anatectic pegmatites with common pockets lined with crystals of smoky quartz, K-feldspar, albite, muscovite, zoned black tourmaline (schorl, oxy-schorl, foitite, dravite, magnesio-foitite) and common to rare accessory minerals – fluorapatite, garnet, cordierite to sekaninaite, TiO₂ phases (anatase, brookite, rutile), and cassiterite are common in the Strážek Moldanubicum but rather rare in other regions of the Moldanubian Zone, Bohemian Massif. Quartz, albite, muscovite, and tourmaline are present in several distinct morphological and paragenetic types. Spatially associated and genetically related muscovite veins are characterized by abundant muscovite, common quartz and tourmaline, feldspars (mainly K-feldspar) are rare. These simple pegmatites represent very specific type of anatectic (abyssal) pegmatites with common pockets, which are typically absent in such pegmatites worldwide.
