RARE-EARTH MINERALIZATION IN CARBONACEOUS SHALE FORMATION ROGOVSKIY TIM-YASTREBOVSKOY STRUCTURE, VORONEZH CRYSTALLIN MASSIF
In carbonaceous shales Rogue Formation Tim-Yastrebovskoy structure rare-earth mineralization is installed, which is presented allanite [CaREEAl2Fe2+Si3O11O(OH)], bastnaesite [(Ce,La)(CO3)F], synchysite [Ca(Ce,La,Nd)(CO3)2F] and monazite [(Ce,La,Nd,Th)PO4 and REE-containing apatite. Parageneses were explored in detail and features of the chemical composition of rare earth minerals
