中文摘要:
      研究区位于南秦岭北大巴山构造带次级构造—焕古滩—流水店复式向形北翼,出露上震旦统—志留系浅海—深海相火山碎屑沉积岩、陆源碎屑沉积岩、生物化学沉积岩建造,其中寒武—奥陶系洞河群为钒矿赋矿层位。含矿岩性为含炭石英绢云母片岩,矿体受层位和F1断裂控制。通过钒赋存状态分析研究,主要载钒矿物为绢云母、蛭石。钒矿以云母类中的钒为主,占75.60%;其次氧化铁及黏土矿物中的钒占21.76%;难溶硅酸盐中的钒很少,占2.64%。研究区钒以低价钒为主,占60.97%,其中三价钒占20.44%,四价钒占40.53%。紫阳钒矿是近年来在陕西南部新发现的中型钒矿床。本文对南秦岭安康—商洛地区寒武系黑色岩系钒矿勘查与开发具有指导意义。
英文摘要:
      The studied area is located in the northern flank of the Dabashan tectonic belt of the north Qinling mountains, where the cambrian-ordovician Donghe formation is composed of vanadium deposits. The ore-bearing lithology is carbonaceous silica sericite schist and the ore body is controlled by horizon and F1 fault. Based on the analysis of vanadium occurrence status, the main vanadium bearing minerals are sericite and vermiculite. Vanadium was mainly in mica, accounting for 75.60%, following by vanadium in ferric oxide and clay minerals accounting for 21.76%, vanadium in refractory silicate was very little, accounting for 2.64%. The vanadium in the study area is given priority to with low vanadium, accounted for 60.97%; Three valence vanadium 20.44%, tetravalent vanadium accounting for 40.53%. Ziyang vanadium deposit is a newly discovered medium-sized vanadium deposit in southern Shaanxi province in recent years. This paper has a guiding significance for the exploration and development of vanadium ore of Cambrian black rock series in Ankang-Shangluo area of south Qinling mountains.
