铀石

主要矿石矿物为晶质铀矿、铀石，铀矿化主要富集在伟晶状花岗岩内黑云母集中区、伟晶状花岗岩脉与黑云母斜长片麻岩接触带处。

Main ore minerals are uraninite and coffinite . Uranium mineralization is mainly present in the biotite-concentrated site within pegmatoid granite and at the contact between pegmatoid granite dykes and biotite plagiogneiss .

铀主要以显微浸染状铀矿物（沥青铀矿+铀石）形式散布于炭屑木质细胞腔内壁和砂岩碎屑颗粒的填隙物中，部分以吸附形式赋存于粘土矿物和炭屑；

Uranium mainly occurs in pitchblende and coffinite which are mainly dispersed in the fossil wood cells and pelitic cement of sandstone detrital grains , and partly adsorbed by clay minerals or carbonaceous debris .
