| Popis | Pegmatites are one of the main sources of some critical elements required for the 'green transition'. This specific lithology is commonly observed as a host rock for polymetallic mineralization in Pb-Zn deposits from the Central Rhodopes in Bulgaria. The main pegmatite-forming minerals are feldspar, quartz and mica. Allanite, titanite, zircon, monazite and apatite are commonly observed as accessory minerals. Despite no genetic relation between the Pb-Zn mineralization and the pegmatites, the latter are altered by the ore-forming fluids in these deposits. The hydrothermal alteration resulted in redistribution of various components to new minerals phases such as thorite, bastnasite, parisite, xenotime, REE-bearing clinozoisite and others. |
