| 中文摘要: |
| 大水西钒矿处于塔里木板块和哈萨克斯坦—北山板块的交接部位,位于天山—北山海槽之东端。钒矿体赋存于下寒武统中,海进时期特别是在下寒武统与蓟县系之间的沉积间断面上。岩石为一套浅海相黑色炭质—硅质岩、硅质岩、泥岩、石墨硅质板岩建造,是该区钒矿的重要成矿岩石组合。区内重力场总体表现为较宽缓的重力低值区；钒主要分布于云母类及高岭土矿物中,少量赋存于电气石、石榴石类矿物中。矿床中非金属矿物有绢云母、堇青石、石墨、石英、绿泥石等变晶矿物,金属矿物有黄铁矿、磁黄铁矿、毒砂、黄铜矿、黝铜矿、铜蓝等。大水西钒矿属于黑色页岩型钒矿床,该种类型钒矿在区域上具有较好找矿前景,通过进一步地质勘探工作有望达到大型矿床规模。 |
| 英文摘要: |
| The Dashuixi vanadium deposit area is located in the eastern end of the Beishan geosyncline and the junction site of the Tarim plate and Kazakhstan plate in northern Tianshan Mountain.The vanadium orebody occurs in the lower Cambrian strata in the transgressive period,especially in the sedimentary discontinuity section between the Lower Cambrian and the Pre-Cambrian Jixian system,the host rocks are a series of shallow marine black formation consisting of carbonaceous siliceous rocks,siliceous rock,mudstone,and graphite siliceous slate. The gravity field in the deposit area generally is a wide gentle low value gravity zone. The vanadium ore is mostly distributed in the mica and kaolin minerals,minor in tourmaline and garnet minerals. The main rock minerals are sericite,cordierite,graphite,quartz,chlorite and other variable crystal minerals.The metallic minerals are pyrite,pyrrhotite,arsenopyrite,chalcopyrite,tetrahedrite,azurite and other metal minerals. Dashuixi vanadium ore deposit belongs to the black shale type vanadium deposit. Based on the comprehensive analysis, there is great prospecting potential in this vanadium ore belt,there is high probability to discover a large-sized vanadium deposit. |
