摘　　要：淅川县老君垭钒矿床位于东秦岭造山带东段,矿体呈层状产于古生界寒武系下统水沟口组地层中,赋矿岩石为黑色泥质岩系。区内K1矿体严格受含矿层控制,总体倾向190°,倾角25°~30°。走向长2495 m,最大斜深1066 m,平均厚度11.12 m,V_(2)O_(5)平均品位1.46%。估算钒矿控制的+推断的V_(2)O_(5)资源量55.73万t,规模为中型。成矿物质钒主要来源于前寒武系地层,含钒岩石经风化、搬运,及有机质黏土吸附沉积而成,为典型的沉积型层状钒矿床。寒武系下统水沟口组含矿地层,地形由高到低突变的低凹处等为寻找该类型钒矿的重要标志。从成矿地质背景、矿床特征、矿床成因及找矿标志等方面加以总结,为该区寻找该类型矿床提供参考。The Laojunya vanadium deposit in Xichuan County is located in the eastern part of the East Qinling orogenic belt.The ore body occurs in the stratum of the Lower Cambrian Shuigoukou Formation of the Paleozoic in layers,and the host rock is black argillaceous rock series.The K1 ore body in the area is strictly controlled by the ore bearing bed,with an overall dip of 190°and an inclination of 25°~30°.The strike length is 2495 m,the maximum inclined depth is 1066 m,the average thickness is 11.12 m,and the average grade of V_(2)O_(5)is 1.46%.It is estimated that the vanadium ore controlled and inferred V_(2)O_(5)resource amount is 557300 t,and the scale is medium.The ore-forming material vanadium mainly comes from Precambrian strata.Vanadium bearing rocks are weathered,transported and deposited by organic clay adsorption.It is a typical sedimentary layered vanadium deposit.The ore bearing strata of the lower Cambrian Shuigoukou Formation and the low depression where the terrain changes from high to low are important indicators for searching for this type of vanadium deposit.A summary is made from the aspects of metallogenic geological background,ore deposit characteristics,ore genesis and prospecting indicators to provide a reference for the exploration of this type of deposit in this area.
