بررسی کانی زایی اورانیوم و عناصر REE و فرایندهای مرتبط با آن در آنومالی ۶ منطقه خشومی ایران مرکزی

Uranium mineralizaition in Khoshomy prospect, located in central part of Iran, with ۳۰۰-۱۵۰۰۰ (cps) and ۱۴ to ۴۰۰۰ (ppm) released. The main rock types include: gneiss, granite, pegmatite and migmatite, that influenced by pegmatite-albitic vines (quartz-heldespatic). Acidic and basic dykes, granodioritic, units and dolomite and marble have been seen. The alteration associated with the mineralization is potassic, argillic, propylitic, carbonatization, silisificaition and hematitizaition. Uranium mineralization occurred in a hydrothermal phase with Cu, Mo, Ni and Au elements. Uranium primary minerals include pitchblend, coffinite, uraninite; and uranium secondary minerals include uranophan and boltwodite. REE mineralization occurred by the potassic phase in pegmatitization process.
