摘　　要：河南省汝阳县小白铅锌矿床成因类型为构造蚀变岩型中—低温细脉浸染状热液矿床。矿体形态、产状与构造蚀变岩带产状一致,倾向北西,倾角75°~88°,平均82°,呈陡倾斜产出。因此,断裂构造破碎带成为地质找矿的主要标志,其次断裂带内的石英脉以及地表铜的氧化矿物孔雀石都是良好的找矿标志。The origin type of Xiaobai lead-zinc deposit in Ruyang County,Henan Province is tectonic altered rock type medium-low temperature vein disseminated hydrothermal deposit.The shape and occurrence of ore are consistent with the structureal altered rock belt.The direction of orebody inclined to north-west with an angle of 75°~88°degrees,average of 82 degree.Therefore,the fracture zone of fault structure becomes the main symbol of geological prospecting,the quartz veins in the fault zone and the oxidized mineral malachite of surface copper are the secondary good prospecting marks.
