摘　　要：黑色岩系在湘西郑家湾矿区广泛分布,是镍-钼-钒矿的含矿岩系。为了明确镍-钼-钒矿体地质特征,对郑家湾矿区开展了详细的野外地质调查和室内分析工作。结果表明:郑家湾矿区寒武系牛蹄塘组底部有钒矿和钼(镍、钒)矿体分布,钒矿体主要位于矿区南部,北部少见,矿体厚度较稳定,主要矿石为含钒伊利石,V_(2)O_(5)平均品位为0.83%。钼(镍、钒)矿体仅位于矿区北部,矿体厚度稳定,矿石成分复杂,矿体Mo、Ni、V_(2)O_(5)平均品位分别为0.15%、0.12%、0.52%。郑家湾矿区钒矿体、钼(镍、钒)矿体为生物成矿作用和热水成矿作用形成,成矿模式有待进一步的研究确定。The black rock series is extensively distributed in Zhengjiawan mining area of western Hunan and constitutes the ore-bearing rock series for nickel-molybdenum-vanadium deposits.This paper conducts a comprehensive field geological survey and indoor analysis on the Zhengjiawan mining area to elucidate the geological characteristics of the nickel-molybdenum-vanadium ore body.The findings indicate the presence of vanadium and molybdenum(nickel,vanadium)deposits in the lower part of Cambrian Niutitang Formation in Zhengjiawan mining area.The vanadium ore deposits are predominantly situated in the southern region of the mining area and are scarce in the northern region.The thickness of the ore bodies remains relatively consistent,with the primary ore being vanadium-bearing illite.The average grade for V_(2)O_(5) is 0.83%.The molybdenum(nickel,vanadium)ore deposit is exclusively situated in the northern section of the mining region.It exhibits a consistent thickness and possesses a diverse composition of minerals.The mean grades of molybdenum(Mo),nickel(Ni),and vanadium pentoxide(V_(2)O_(5))in the ore deposit are 0.15%,0.12%,and 0.52%,respectively.The vanadium and molybdenum(nickel,vanadium)deposits in Zhengjiawan mining area are the result of both biological mineralization and hydrothermal mineralization.However,further research and investigation are required to determine the exact mineralization model.
