The maj or ore-bodies in Youziping Pb-Zn deposit are vein deposit that controlled by fault F1 ,the metallotectonics of its single vein can be divided into shear belt type and shatter belt type.Shatter belt type vein is in irregular shape or chambered shape,and its spatial pattern is in line with fault and shatter belt,and the mineralization is uneven and low graded.Shear belt type vein is in lenticular shape,and its metallotec-tonics is characterized by parallel composite veins,vein in vein and hydraulic pressure crack,and the mineral-ization is enriched and high graded.The industrial ore-bodies are vein groups which consist of multiple shat-ter belt type and shear belt vein type single veins.It is believed that fault F1 is both an ore conducting struc-ture and an ore hosting structure,and multiphase tectonic activity is the maj or cause of above-mentioned characteristics.%柚子坪铅锌矿的主要矿体是受 F1断裂控制的脉状矿床，其单脉的成矿构造可分为剪切带型与破碎带型两种类型。破碎带型矿脉多呈不规则状、囊状，空间分布与断裂破碎带一致，矿化不均匀且品位低；剪切带型矿脉多呈透镜状，其成矿构造具有平行复脉、脉中脉及矿液压裂等特征，矿化较富集且品位高。工业矿体是由多个破碎带型或剪切型单脉组成的脉群。认为 F1断层既是导矿构造，又是储矿构造，多期次的构造运动是形成上述构造特征的主要原因。
