| Popis: | Narigan area in the southern part of the Bafq-Saghand metallogenic zone in Central Iran is a host of davidite-bearing quartz veins. Davidite is an important key mineral for exploration of not only uranium but also REE's in Central Iran. Narigan granite in the Narigan area is characterized by high-K calc-alkaline nature and its parental magma was partially contaminated by the Precambrian crust. The REE pattern of quartz veins is brought about by REE contents in davidite. The homogenization temperatures of vapor-liquid-solid (V-L-S) fluid inclusions in quartzes are >500˚C in quartz veins. Furthermore, the ∑REE contents (71910 to 90292 ppm) and U/Th ratios ( |
