辽宁省上东沟铅锌矿地质特征及成矿规律分析

Geological Characteristics and Metallogenic Regularity of Shangdonggou Lead-Zinc Deposit in Liaoning Province

上东沟铅锌矿位于中朝准地台的辽东台隆之辽东裂谷,辽东裂谷古地理为海浸、海退频繁交替的沉积环境,为裂谷Ⅲ级海湾泻湖相盆地。通过对工作区进行地质勘查以及对区域成矿条件、成矿规律进行研究,对区内可能形成铅锌矿床的三至四级海相盆地进行综合分析,结合地表矿化信息、物化探异常对上东沟铅锌矿进行成矿预测。作为该矿床的主要工作者,提出对该矿成矿规律及找矿条件初浅认识,供同仁们在该区域找矿参考。

The Shangdonggou lead-zinc deposit is located in the Liaodong Rift of the Liaodong Tailong of the sino-korean paraplatform,the palaeogeography of Liaodong Rift Valley is sea-immersion,Sedimentary Environment with frequent alternation of regression,it is a Grade III Rift Bay Lagoon Basin.Through the geological exploration of the work area and the regional metallogenic conditions,on the metallogenic regularity,a comprehensive analysis is made on the third to fourth grade marine basins in the area where lead-zinc deposits may be formed.Combined with surface mineralization information,Geophysical and Geochemical Anomaly metallogenic prognosis of Shangdonggou lead-zinc deposit.As the main workers of the deposit,this paper puts forward a preliminary understanding of the metallogenic regularity and prospecting conditions of the deposit,which can be used as a reference for colleagues in prospecting in this area.
