陕西岚皋沙沟钒矿地质特征及成矿作用浅析

Geology And Metallogenic Mode Of Vanadium Ore In Shagou Area Of Langao County In Shaanxi

陕西岚皋沙沟钒矿位于北大巴山早古生代裂谷带内,赋存于下寒武统鲁家坪组第二岩性段第一岩性层。通过野外勘查、测试分析和综合研究,在矿区内共圈定5条主要钒矿体,矿石类型主要为碳硅质岩型钒矿石。矿石矿物主要为石英,其次为绢云母及少量黄铁矿、绿泥石等,绢云母为矿石中主要有用矿物,也是钒的主要载体矿物。该钒矿床受层位控制明显且规模较大,将为该区同类矿床暨新一轮找矿战略行动的项目部署及找矿突破提供借鉴意义。

Shagou vanadium deposit occurs in the first lithologic layer of the second lithologic member of the Lujiaping Formation of the Lower Cambrianin in the early Paleozoic rift zone of the North Bashan Mountain in Langao county of Shaanxi Province.Based on ore prospecting in field,experimental analysis and comprehensive research,five main vanadium ore bodies have been delineated in the mineralized area,including carbon-siliceous vanadium ore and quartz,sericite and a small amount of pyrite and chlorite.Sericite in this area is the major ore-carrier mineral of vanadium.The vanadium deposit is obviously controlled by strata and has a large scale.Research on the deposit in this area would provide basic guidance for further prospecting similar ore deposits in the metallogenic belt.
