| 摘 要： | 江西千子岭铅锌矿床是钦杭成矿带江西段核部新发现的一处隐伏矿床,成矿定位于信江中新生代断陷盆地北缘大断裂;铅锌矿体赋存在EW向硅化破碎带中,矿石为块状热液硅质岩-闪锌矿-方铅矿(黄铜矿)-萤石组合,容矿热液硅质岩从地表到深部表现为无矿化→铅锌矿化→铅锌铜矿化的垂向矿化分带特征。EW向容矿破碎带卷入上白垩系紫红色砂岩,推断铅锌(铜)矿化属喜山运动的产物。

Geological characteristics of Qianziling Pb-Zn deposit in Jiangxi |

| Abstract: | Qianziling Pb-Zn deposit in Jiangxi is a newly discovered concealed deposit in the core part of Jiangxi section of Qin-Hang metallogenic belt,and the mineralization is located in the major fracture at the north margin of Xinjiang Meso-Cenozoic downfaulted basin.Pb-Zn orebodies occur in the EW-trending silicified fracture zone,and the ores are mainly a combination of massive hydrothermal siliceous rock-sphalerite-ga-lena (chalcopyrite)-fluorite.The ore-hosting hydrothermal siliceous rock has vertical mineralization zoning characteristics which occur as unmineralized → Pb-Zn mineralized → Pb-Zn-Cu mineralized in form from sur-face to deep part.The fact that the EW-trending ore-hosting fracture zone is involved in Upper Cretaceous mauve sandstone indicates that the Pb-Zn(-Cu)mineralization is a product of Himalayan movement. |
