MINERALIZERS IN URANIUM ORE ALBITYTES UKRAINIAN SHIELD
Tectonics and Stratigraphy, 2017 Уперше для уранових родовищ альбітитової формації Українського щита вивчено головні мінералізатори. Ізотопно-геохімічні методи їхнього вивчення дали змогу встановити, що мінералоутворювальна система в процесі урановорудного натрієвого метасоматозу функціонувала в режимі багаторазової взаємодії збагачених ураном формаційних (порових) розчинів і ...
