摘要
晋冀成矿区位于华北陆块中部,华北陆块是我国地质历史演化最久,发育较为齐全,构造岩浆活动极为复杂的地区,广泛出露的太古宙-古元古代结晶基底的变质岩层,其出露面积占陆块面积约20%。由于长期、多次的地质活动,有利于本区形成铁、金、银、铅、锌、钼、铜等矿床。根据晋冀成矿区的主要成矿特征、典型矿床及找矿新发现,结合多元信息综合分析,对各个成矿区带进行资源潜力评价、划分找矿远景和勘查选区,并提出了部署建议。
Jin-ji metallogenic belt is located in the middle part of the North China block,The North China block is the most developed region in China with a long history of geological evolution and complicated tectonic magmatic activity, The metamorphic strata of the Archean Proterozoic crystalline basement, which are widely exposed, account for about 20% of the block.Because of long-term and repeated geological activities, it is favorable for the formation of iron, gold, silver, lead, zinc, molybdenum, copper and other deposits in this area.According to the multivariate comprehensive analysis of mineralization characteristics,typical deposits and new prospecting discoveries,we evaluated the mineral resources potential and prospecting potential,pointed out the mineral prospects and exploration areas,and put forward proposals for further work of Northwest China.
