| 摘 要： | 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.

| Abstract: | The main Orebody of Youziping Pb-Zn deposit is the veined orebody controlled by fault F1, the single vein metallogenetic structure can be divided into shear zone and fracture zone 2 types. The fracture zone type ore veins are mostly irregular, chambered, distribution consistent with that of the fault fracture zone, metallogene- sis uneven and grade low; shear zone type ore veins mostly lenticular, metallogenetic structure characterized by parallel composite vein, vein in vein, compression fracture of ore fluid, metallogenesis concentration and grade high. The commercial orebody is composed of vein group of many fracture zone type or shear zone type single veins. We think the fault F1 is not only the ore channel structure but also the ore-bearing structure. The main origin of forming the structure feature mentioned above is the multiple periods of structural activities. |
