| 摘 要： | 山东龙口市大磨曲家金矿区位于沂沭断裂带东侧，招平成矿带北端。矿床矿化类型为含金蚀变岩型，矿床经历了热液和表生 2 个成矿期及 5 个成矿阶段，围岩蚀变主要为硅化、绢云母化、钾化等。通过对 302 号脉坑道及钻孔岩心原生岩石地球化学特征研究，提出矿体前缘指示元素组合为 Hg-- As--Sb，近矿或矿体指示元素组合为 Au--Ag--Cu--Pb--Zn，矿体尾晕指示元素组合为 Bi--Co--Ni; 据此，建立了地球化学勘查模型。

| Abstract: | Damoqujia gold deposit in Longkou of Shandong is located in the east part of Yishu fault belt and the north part of Zhaoping gold ore-forming belt. The mineralization type of the deposit is a gold-bearing alteration type. The deposit experienced two metallogenic periods （hydrothermal metallogeny and supergenic metallogeny） and five metallogenic stages. The wall-rock alteration were mainly silicification, sericitization and potassic. Through the research of the geochemistry characteristics of mineral vein No. 302 and primary rocks, the authors proposed that the guide elements of front halo of ore-body were Hg-As-Sb, the guide elements of near ore or ore-body were Au-Ag-Cu-Pb-Zn, and the guide elements of rear halo of ore-body were Bi-Co-Ni. Accordingly, the geochemical exploration model was established. |
