摘　　要：焦家金矿田断裂构造及控矿特征研究表明,该区断裂构造经历了早期韧性剪切和晚期脆性叠加作用,地质演化经历了初始矿源层的形成—成矿元素活化、迁移初步富集—再度活化富集达到工业矿体定位历史过程;早期韧性构造与晚期脆性构造的叠加复合直接控制了金矿床(点)的似等距性分布及矿体的产状、形态等特征。Based on the research of the feature of faulted structure ore-controlling and ore-controlling mechanism in Jiaojia gold field, the paper holds that the faulted structure experiences the superposition process of early ductile shearing structure and late brittle rifling structure, and the geologic evolution concluds the process of formation stratum containing gold, gold activation, migration, preliminary enrichment, second activation, migration and enrichment to form industrial orebody in favorable space. Superposition of early ductile shearing structure and late brittle rifling structure directly controls the feature of the equidistant distribution of gold deposit and such features as forms and occnrrences of orebody, etc.
