    DISCUSSION ON THE METALLOGENY AND GENESIS OF THE LEAD-ZINC DEPOSITS IN QINGCHENGZI OREFIELD, LIAONING PROVINCE

    • 摘要: 青城子铅锌矿成矿受层位、岩性控制.古元古代条痕状花岗岩侵位而引起的穹隆构造及其上覆的层状岩系中的滑脱型韧性剪切带、层间断裂带及中生代岩浆作用、断裂构造对成矿起重要作用.矿床具有“多阶段复成因”特点,经历了3个主要成矿期,即古元古代同生沉积就位成矿期、吕梁变质-变形“重就位”成矿期和中生代构造-岩浆活化“再就位”成矿期.矿床成因属以海底(喷流)热水沉积作用为基础,遭受后期变质变形和热液叠加的广义层控性矿床,即属海底喷气沉积变质-岩浆热液改造型铅锌矿床.

       

      Abstract: The metallogenesis of Qingchengzi Pb-Zn deposits is controlled by strata and rock formation. The dome structure caused by the emplacement of Paleoproterozoic granite, the ductile shear zone and interlayer fault in overlying stratiform rock series, and the Mesozoic magmatism and fault structure significantly contribute to the metallogenesis. The ore deposits are of complex polystage, with three metallogenic epochs during the periods of Paleoproterozoic synsedimentation emplacement, Luliangian metamorphic-deformation re-emplacement and Mesozoic tectonomagmatic reemplacement, respectively. The deposits are genetically stratabound ones with metamorphism-deformation and hydrothermal superimposition on the basis of submarine (spout) hydrothermal deposition, belonging to submarine exhalation sedimentary metamorphic-magmatic hydrothermal reformation type.
