| 中文摘要: |
| 烟棵冲钒矿床地处秦岭—大别造山带秦岭弧盆地东南段的随南陆缘裂谷南缘。本文在系统分析烟棵冲钒矿床地质特征的基础上,初步探讨了矿床成因及找矿标志。结果表明:矿区内钒(钼)矿体主要赋存于下寒武统杨家堡组黑色硅质岩与庄子沟组黑色岩系中,矿体呈层状、似层状和透镜状产出,产状与地层产状近乎一致,主要矿体在走向上矿化较连续,含矿层位稳定;矿石类型主要有硅质(板)岩型钒钼矿石、(含碳)硅质板岩型钒矿石、含磷结核硅质板岩型钒矿石和泥质板岩型钒矿石;以含磷结核硅质板岩型钒矿石的含钒量最高,主要的含钒矿物为含钒水云母。综合分析认为,烟棵冲钒矿床为海相热水(喷气)和生物化学沉积相互作用形成的沉积型层控矿床;主要找矿标志为寒武纪地层、黑色岩性、V-Mo-Ag-Pb综合异常与重砂异常叠合区等。 |
| 英文摘要: |
| The Yankechong V deposit is located in the southern margin of Suinan continentent marginal rift in the southeast Qinling arc basin of the Qinling-Dabie orogenic belt. Based on the systematic analysis of the geological characteristics of the deposit, the genesis and prospecting mark are preliminarily discussed. The mainV (Mo) orebodies mainly occur in the black siliceous rocks of the Lower Cambrian Yangjiapu Formation and the Zhuangzigou Formation. They are stratified and lenticular almostly coincided with the strata. The mineralization of main ore bodies is continuous along the strike and the ore-bearing horizon is stable. There are mainly four ore types i.e. siliceous (slate) type of V-Mo ore, carbonaceous siliceous slate type of V ore, phosphorous siliceous nodule slate type of V ore and argillaceous slate type of V ore. The phosphorous siliceous nodule slate type is with the highest V content. Hydromica is the main V-bearing mineral. The Yankechong vanadium deposit is a interacted hot water exhalation and biochemical deposition stratabound deposit. The main prospecting marks are Cambrian strata, black lithology, overprinting area of V-Mo-Ag-Pb composite anomaly and heavy sand anomaly. |
