摘　　要：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 studies indicate that the metallogenic materials mainly comes from the core-mantle areas of the earth in the form of gaseous-gas-liquid mixed state-ore-bearing fluid. They migrated to the duc-tile-brattle zones, intruded internal and external contact zones of intrusives, contact zones between dykes and country rocks and formed mineral resources through mantle plumes to sub-mantle plumes and mantle branch structures, favorable tectonic extension zones. Ordered combination of ore fields, deposits and ore-bodyies（veins ） of different deposit types have been formed as well. Therefore, tectonic ore-forming and ore-controlling should be paid more attention in order to guide the new round of geological prospecting and mineral resources evaluation. Cross cutting relation of Jiaojia fault and Sanshandao fracture in north-west Shandong Peninsula and its ore-controlling have been analyzed in this paper.
