| 摘 要： | 稀散元素因其在地质体中极分散的特点,极难形成独立矿床。通过找矿预测研究,在四川旺苍地区二叠系吴家坪组一段首次发现了独立的铼硒富集层位,具沉积改造成矿特征。局部地段稀疏钻探工程探获铼资源量61.4 t,硒3000 t,显示了巨大的铼硒找矿潜力。考虑到同层位钒钼矿层形成分层富集、相互伴生,矿石经济可选,综合回收元素多的特点,本区有望成为中国紧缺新兴战略资源成矿新类型的重要成矿带,且具有赋矿层位稳定、矿化均匀、规模巨大的特点。

| Abstract: | Due to extremely scattered characteristics of rare and dispersed elements in the geological body,it is extremely difficult for them to form their own independent deposits.According to the study of prospecting prediction,an independent Re and Se enrichment stratum featuring sedimentation-reformation genesis was first discovered in the first member of Wujiaping Formation in Wangcang,Sichuan.By means of sparse drilling engineering in partial areas,the authors obtained 61.4 tons of rhenium and 3000 tons of selenium resources,which show that there is huge prospecting potentiality of rhenium and selenium.With the characteristics of forming stratified enrichment,the co-existence of V and Mo seams in the same formation,the existence of economical and optional ores and the probable comprehensive recovery of many elements,the area is expected to become an important metallogenic belt of new types of mineralization of shortage emerging strategic resources in China.The deposit shows such characteristics as stability of ore-bearing stratum,uniform mineralization and huge scale. |
