| 摘 要： | 中国大兴安岭地区位于东西向古生代古亚洲构造成矿域与北北东向中新生代滨西太平洋构造成矿域强烈叠加、复合、转换的部位。从而使大兴安岭地区的成矿地质条件优越、成矿期次多、成矿强度大、矿床类型多样。近年来区内找矿工作有了新突破 ,对内生金属矿床区域成矿规律的认识也有了新的进展 ,文中试图作一个阶段性的总结。文章将大兴安岭地区对照其大地构造单元划分成 4个成矿带 ,总结了两期主要成矿期 (海西期和燕山期 ) ,归纳出两大主要成矿系列 ,并分别就最近几年的新成果进行了典型矿床的举例 |

| Abstract: | The Da Hinggan Ling area is located at the supperimposed, composite and transformed portion, where the Mesozoic NNE-stretching tectonic domain of the global Circum-Pacific belt strongly overprints the Paleozoic E-W-stretching tectonic domain of the Paleo-Asian Ocean. Because of this peculiar tectonic setting, strong ore-forming events occurred repeatedly in the Da Hinggan Ling, resulting in abundant various types of polymetallic ore deposits and complex features of regional metallogeny. Recently, a number of promising ore occurrences were discovered in the Da Hinggan Ling, and new progress was achieved in the study of regional metallogeny of the Da Hinggan Ling. In this paper, the authors try to give a short summary on these new approaches. Four metallogenic zones are identified according to the tectonic framework. Two principal metallogenic events and two principal metallogenic series are summarized. Several newly discovered deposits are described as typical examples. |
