Genesis and Prospecting Marks of Zhaojiapuzi Gold Deposit

摘要: 赵家堡子金矿位于猫岭-卧龙泉金矿化集中区，是典型的中低温热液矿床。通过区域变质作用，使岩层中的Au、Ag等成矿元素活化，随着变质热液运移到有利的构造部位初步富集；通过应力作用，使岩石发生塑性变形，形成了北西向的韧性剪切带。同时，使Au、Ag等成矿元素再次活化转移、富集；通过后期构造岩浆的大面积侵入，形成了叠加在韧性剪切带之上的北西向韧-脆性断裂和北东向的脆性断裂，同时宏大的热源使地层中的Au再次活化、迁移、富集，同岩浆所带来的大量成矿物质一起在有利的构造部位富集成矿，是本区金矿的主要成矿阶段。Abstract: Situated in cat RidgeMaoling~and Wolongquan gold mineralization concentration area, Zhaojiapuzi gold deposit is is a typical mesothermal-of the epithermal deposits. Through Regional metamorphism of rocks activated metallogenic elements such as while Au, and Ag ore-forming elements such as activation, who migrated with metamorphic hydrotherm and enriched initially in favorable tectonic settingswith metamorphic hydrothermal favorable structural parts migrated preliminary enrichment. Under the effect of stress, Through stress, so that the plastic deformation of rocks, was aroused to forming a NW-trending ductile shear zone, whileand the ore-forming elements such as Au, and Ag again ore-forming elements such as remobilizationed again, and enrichmented;. Then through a large area of the late magmatic intrusion, forming formed a NW-trending ductile-brittle fracture and a NE-trending brittle fault superimposed on top of the ductile shear zones superimposed on top of the NW-trending ductile-brittle fracture and the North East to brittle fracture. Meanwhile, the while ambitiouenormouss heat sources formations gold acaused another gain activation, migration, and accumulation of the minerals, enriched and mineralized at favorable structural positions with a large number of metallogenic material brought by magma, whichtic minerals brought together into a large number of favorable structural positions in enrichment and mineralization, this area is a major stage of mainly intothe gold mineral phasedeposit mineralization in this area.
