| 摘 要： | 西邑铅锌矿主要赋存于下石炭统香山组（C1x）地层中,矿床成因为沉积岩容矿的海底喷流沉积型（SEDEX型）铅锌矿床.矿体顶板炭质层厚度与矿体厚度显示出具正相关关系.根据矿体与相邻地质体及地质现象的关系,结合区内找矿实践,直接找矿标志有：铁帽、构造破碎带、重晶石化等,间接找矿标志有物、化探异常等.

| Abstract: | Xiyi Pb-Zn deposit is mainly in Lower C Xiangshan Formation （Clx）. The genesis of it belongs to the submarine effusive sedimentary type （SEDEX type） Pb-Zn deposit in ore-bearing sedimentary rock. The thickness of top wall carbonaceous bed of ore body is correlated positively with the thickness of ore body. According to the relationship between ore body and nearby geological body, feature, in combination with the prospecting practice in this area, the direct prospecting criteria are gossan, structure fracture zone, baritization, etc, the indirect ones are geophysical, geochemical anomaly, etc. |
