| 摘 要： | 广西贵港-平南地区是热水沉积改造型层控铅锌铜矿床集中区.该区铅锌铜矿主要控矿层位为中泥盆统四排组-应堂组及东岗岭组中段,以深灰-灰黑色含炭质白云岩夹薄层状炭质泥岩控矿为特征;控矿构造主要为复式背、向斜的翼部单斜构造,燕山晚期再次成矿时,与含矿层叠加的断裂和岩浆侵入构造则是热水沉积改造型矿床的主要控矿构造.矿床形成是经深循环作用使含矿热卤水进入沉积盆地局部沉积而成,成矿作用主要发生在同生-成岩晚期,燕山期构造热液和岩浆热液改造带形成叠加改造型矿床.

| Abstract: | The Guigang-Pingnan area in Guangxi province is a concentration region of sedimentary exhalative reformation type stratabound lead-zinc-copper deposits. The main controlling strata of the deposits in the area are middle Devonian Sipai Formation-Yingtang Formation and the middle section of Donggangling Formation, which being dark grey and grey-black carbonaceous dolomites intercalated with thin carbonaceous mudstones. The main ore-controlling structures are monocline in the limbs of anticline and syncline. When mineralization occurred again in Yanshanian, the superposed faults developed in the mineralized strata and magma intrusive structures are the main ore-controlling ones. The deposits are formed during deep circulation of ore fluids which went into basin. Mineralization was mainly occurred in the late stage of syngenetic diagenesis. The deposit was formed by overprints of Yanshanian structural fluids and magmatic fluids. |
