The mineral diversity of the Urdini Lakes and the glacial valley of the Urdina River (Rila Mountain) – an overview

An overview of different types mineralization in the area Urdini Lakes and glacial valley Urdina River (northwestern Rila Mountain) has been made. Currently, it is only protected for minerals Bulgaria. In this area, mainly pegmatite, but also skarn alpine-type mineralizations, have found to date. Of particular interest are hybrid desilicified type pegmatites containing emerald, aquamarine chrysoberyl crystals extremely rare native aluminum. The mineralizations from characterized by wollastonite, diopside, garnet (grossular, andradite), zoisite, clinozoisite, scapolite, vesuvianite others. well-formed quartz, adular, epidote pyrite, as well nests almandine with albite, were observed recrystallization previously formed cavities host rocks. These may occasionally contain zeolites.
