【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;铅锌矿体赋存在东西向硅化破碎带中,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。东西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。更多还原

【Abstract】 Qianziling Pb-Zn deposit is a new concealed deposit in the center of Jiangxi section of Qin-Hang Mineralization Belt,The Pb-Zn deposit was localized in a major fracture of north marin of Xinjiang Meso-Cenozoic fault-depressed basin.Pb-Zn ore body hosting in EW strike fracture zone,and its ore compositions are hydrothermal siliceous rocks-lead-zinc(chalcopyrite)- fluorite.From the surface to the deep,vertical mineralization zoning characteristics of the hydrothermal siliceous rocks mainly for No mineralization zone→Pb-Zn mineralization zone→Pb-Zn-Cu zone.Base on the fact that upper Cretaceous purplish-red sandstone occurred in EW strike fracture zone,We inferred the Pb-Zn(Cu) mineralization was a product of the Himalayan movement.更多还原
