通过对华北地台北缘多金属硫铁矿成矿构造环境、含矿建造、矿床成因类型、矿床地球化学等几个方面的综合研究。将华北地台北缘元古宙狼山-渣尔泰山、燕辽、辽东-吉南三大矿集区进行对比,认为该区矿床时控和层控性明显,且多受裂陷槽内次级断陷盆地的制约。具成层性,侧向延伸较稳定,有规律的成群成带分布,多具同生和后生成因叠加的特点。各矿床主要为海底喷气成因,在矿床形成时间、受构造与岩浆作用的影响及含矿岩系组合等方面又有一定差异。根据成矿规律,划分出17个成矿远景区。
Through comprehensive research on the metallogenic tectonism, ore-bearing construction, genesis type of deposit and geochemistry of ore deposit in the northern margin of North China Platform. Comparison of the Proterozoic Langshan-Zarutaishan, Yanliao and Liaodong-Ji Nan three ore-collecting areas in the northern margin of North China Platform shows that the timeliness and stratabound control of the deposits in this area are obvious, Restrictive basin-level constraints. With stratification, the lateral extension of a more stable, regular distribution of flocks, with more than the same generation and after the formation of superposition characteristics. Each deposit is mainly the genesis of the submarine jet, and there are some differences in the formation time of the deposit, the influence of tectonism and magmatism and the combination of the ore-bearing rock series. According to the metallogenic regularity, 17 metallogenic prospective areas are divided.
