通过对成矿地质背景、成矿物质来源、成矿物质运移方式和成矿富集条件的综合研究 ,认为八卦庙金矿床的成矿物质来源于下地壳 (太古代 )结晶基底。主要成矿期和成矿方式为 :晚泥盆世发育在秦岭微板块伸展背景下与同生断裂伴生的海底热水喷流活动 ,在热水沉积洼地沉积的热水混合浊积岩相是矿区的含矿建造 ;华力西—印支期矿区发育的脆—韧性剪切作用控制着金的成矿过程并形成金矿体的主体 ;燕山期陆内运动形成的岩浆气液对金矿的再次叠加富集最终形成金矿床 ;因而具有多期次复合成矿的特点。与成矿期和成矿方式相对应 ,其成矿富集条件为 :晚泥盆世三级热水沉积盆地中的次级裂陷槽 ;脆—韧性剪切带中的构造岩和构造扩容空间 ;NE相节理石英脉。八卦庙金矿可能是地幔柱或热点一个长期活动的结果。
Based on the comprehensive study on the metallogenic geological background, the source of metallogenic material, the mode of metallogenic material migration and the conditions of metallogenic enrichment, it is considered that the ore-forming material of Baguamiao gold deposit comes from the lower crust (Archean) crystalline basement. The main mineralization and metallogenic methods are as follows: the late Devonian developed the seafloor hot-water jets associated with syngenetic faults under the extensional Qinling microplate and the hot-water turbidite phase deposited in the hot-water depressions The ore-bearing construction in the mining area; the brittle-ductile shear development developed in the Warisi-Indosinian mining area controls the gold mineralization process and forms the main body of the gold ore body; and the magmatic gas-liquid formed during the Yanshanian intra- Again superimposed enrichment eventually formed gold deposits; thus has the characteristics of multi-stage complex mineralization. Corresponding to the metallogenic stage and metallogenic methods, the metallogenetic enrichment conditions are: the secondary rift trough in the third-order hydrothermal sedimentary basin in the Late Devonian; the tectonic rocks and tectonic expansions in the brittle-ductile shear zone Space; NE phase quartz vein. The Gossamer Temple goldmine may be the result of a long-term activity of mantle plumes or hot spots.
