| 摘 要： | 铁炉湾铅锌矿位于银洞梁-铅硐山次级热水盆地东北端，具有形成“热水喷流沉积-改造型”铅锌矿床的有利成矿环境，矿床赋存于星红铺组第3岩性段中部，矿体受结晶灰岩、结晶白云岩及层间断裂控制。已发现的矿体具有一定的规模，且有向深部变好的趋势，物化探异常亦显示其深部找矿前景较好。在凤太矿田泥盆纪次级热水沉积盆地中已发现3个赋矿层位。以往的铅锌找矿工作都是以古道岭组灰岩与星红铺组千枚岩接触带为主要勘查对象，而没有对星红铺组中的铅锌矿勘查引起足够的重视，铁炉湾铅锌找矿工作的不断加强，将会取得较好的成果，进而开展在广泛分布的星红铺组第三岩性段中寻找铅锌矿的工作。

| Abstract: | Tieluwan lead-zinc deposit located the northeastern of Yindongliang-Qiantongshan subhydrothermal-basin, have favorable mineralization setting to form lead-zinc deposit of hydrothermal sedimentary -rebuilt type. The deposit ocurrances in the middle stratiomere Xinghongpu Formation, orebodies controlled crystal carbonatite rock, dolotite and interstratified faults, have large scale and become better along dip direction, implied better ore-searching foreground in the deep by geophysical and geochemical anomaly. There are three ore-bearing strata in Devonian hydrothermal sub-basin of Fengtai metallogenic zone, the intermediate zone between carbonatite of Gudaoling Formation and phyllite of Xinghongpu Formation was considered to be main prospecting object, as ignoring the prospection of lead-zinc deposit within the later Formation, the achievement which would be obtained, would be the factor to promote ore-searching for lead-zinc deposits in third stratiomere of Xinghongpu Formation, which distributed widespreadly. |
