研究认为金等成矿物质主要来自核-幔源区,以气态-气液混合态、含矿流体的形式,通过地幔热柱→地幔亚热柱→幔枝构造→有利构造扩容带,迁移到幔枝构造外围的韧脆性剪切带、侵入岩体的内、外接触带、各种脉岩与围岩的接触带等有利部位集聚成矿,并构成矿田→矿床→矿体(脉)的有序排列组合,表现出不同的矿床类型。因此,应侧重研究构造成矿控矿作用,以指导新一轮地质找矿和矿产资源评价。文中还举例分析了胶西北焦家断裂与三山岛断裂的交切关系及其控矿作用。
The study suggests that the gold and other metallogenic materials mainly come from the core-mantle source zone, migrating to the favorable extensional zone through the mantle thermal column → mantle sub-thermal column → mantle branch structure in the form of gas-gas-liquid mixed fluid and ore-bearing fluid Ductile brittle shear zone around the periphery of the mantle branch structure, the inner and outer contact zones of intruded rock mass, contact zones of various vein rock and surrounding rock, and other favorable sites for the accumulation of mineralization and the formation of orefield → deposit → ore body (vein) The orderly arrangement of combinations, showing different types of deposits. Therefore, we should focus on studying the role of tectonic mineralization to guide a new round of geological prospecting and mineral resources assessment. An example is also given to analyze the relationship between the Jiaojia fault and the Sanshandao fault in the Jiaonan area and its ore-controlling effect.
