TOWARDS THE ONTOGENESIS OF BERYL IN GRANITE PEGMATITES SVETLINSKY DEPOSIT IN THE SOUTHERN URALS
We have established small syntactic accretions of quartz, muscovite, and gahnite in the process microprobe study of a beryl crystal containing a fragment of cloudy early beryl. Together with them, sulfides with random orientation were observed - pyrite, chalcopyrite, sphalerite and galena, as well as carbonates - manganese calcite and siderite. Fragments of early turbid beryl in late transparent beryl indicate intramineralization tectonics during the formation of granite pegmatites of the Svetlinsky deposit in the Southern Urals.
