| 摘 要： | 淅川李家湾钒矿处于扬子板块北缘,赋存于下寒武统水沟口组中下部。矿石类型为硅质岩型、页岩型及混合型三种。w（V2O5）一般在0.95%-1.34%。钒主要富集在下部硅质岩、上部杂色页岩,其中硅质岩与页岩互层者,以页岩为主,厚度大于硅质岩的组合内。钒的赋存状态呈高度富集和稀散分布两种。主要以离子吸附和类质同象赋存于粘土矿物中。与钙、钡呈正相关。矿床成因为陆棚相—浅海相层状沉积矿床。

| Abstract: | The Lijiawan vanadium deposit of Xichuan country is located at the north rim of Yangzi plate,hosted in lower part of the lower Cambrian Shuigoukou formation.The type of the ore is siliceous rocks,shale or a mixture.V2O5 content is about 0.95-1.34%.Vanadium is rich in the bottom of the silicolite,upper of the variegated shale.In which the silicolite and the shale interbedding is mainly shale.The vanadium＇s mode of occurrence is highly rich or dispersion,which mainly occurred in the clay mineral by adsorption and isomorphism.It is positive correlation with calcium and barium.The contributing factor is continental shelf facies-shallow sea lamellar phase sedimentary ore deposit. |
