公鹅屯-青阳地区处于扬子准地台与华南褶皱带过渡地段。区内成矿条件较好,已发现多处中小型沉积型钒矿床。区域含矿层位为寒武系下统九门冲组（1jm）。矿体呈层状、似层状、扁豆状顺层产出,严格受地层、岩性、古地理等控制。通过对该区钒矿产出地质特征,矿体与地层、岩性的关系,钒的富集规律、赋存状态等进行研究,新发现具有工业价值的矿体主要产在距底部9.08m厚的炭质页岩、粘土岩内,地表氧化矿石V2O5品位比深部高。钒的富集与A l2O3呈正相关关系,与碳的相关性不甚明显,钒主要是以类质同像形式存在于粘土矿物—伊利石（水云母）族晶格中。提出了区内钒矿找矿标志主要为地层层位、岩性、古地理环境、微化特征。

Gongetun-Qingyang area is located transitional slope belt of Yantze platform and Jiangnan old land,the metallogenic condition in this area is good and many middle scale sedimentary vanadium deposits were founded.The regional ore bearing stratum is occurred in Jiumenchong formation（1jm） of Lower Cambrian,the ore body occurred consequently in the bottom of black carbonaceous shale rock as layer,quasi-lamellar and lenticular.By study the relation of geologic characters and stratum,lithlogy of vanadium occurrence,the concentrating regulation of vanadium ore,it＇s known the new discovered ore bodies occurs in the carbonate shale and claystone 0.98m form the bottom,the taste of surface oxide ore V2O5 is higher than it in deep side.The concentration of vanadium is positive-correlation relation with Al2O3,and the relation with carbonate is not obvious,vanadium mainly exists as isomorphism in the clay mineral： illite lattice.It＇s thought that the vanadium exploration target in this area are stratum position,lithology,paleogeographic environment and microchemical features.
