摘要:

在区域地质背景分析和典型矿床研究的基础上,通过对大兴安岭中南段铜多金属矿床成矿地质特征的分析,阐明了该区铜多金属矿床的空间分布、容矿围岩、与成矿有关岩体和成矿时代,运用区域成矿学研究方法将该区铜多金属成矿初步划分为燕山期斑岩热液、印支—燕山期动力热液和晚华力西—燕山期热水喷流沉积叠加后期热液3个成矿系统。研究表明,本区应重视在侏罗世—白垩世火山岩区寻找大型铜多金属矿床,加强在已知矽卡岩型或热液脉型矿床的深部和外围寻找斑岩型矿床。

Abstract:

Based on the analysis of regional geological setting, metallogenic characteristics and the study of typical deposits, the spatial distribution, orebedding rocks, related intrusions and mineralization ages of copper polymetallic deposits are summarized in the middlesouthern part of Da Hinggan Mountains. Three metallogenic systems of copper polymetallic deposits, which are Yanshanian porphyry hydrothermal, IndoYanshanian hydrothermal dynamic and Late VariscanYanshanian SEDEX deposition superimposed by late hydrothermal solution, are distinguished by using the method of regional metallogeny. The studies indicate that largescale copper polymetallic deposits in JurassicCretaceous volcanic area should be paid more attention to. Also, prospecting exploration of porphyrytype deposits should be strengthened in the depth and around the known skarntype and hydrothermal veintype deposits.

Key words: copper polymetallic deposit, characteristics of regional metallogeny, metallogenic system, middlesouthern part of Da Hinggan Mountains
