中国北方造山区显生宙地质历史重建与成矿地质背景研究进展

New Developments on the Reconstruction of Phanerozoic Geological History and Research of Metallogenic Geological Settings of the Northern China Orogenic Region

简要概述了近3年对中国北方造山区地壳基本构造格局开展综合调查与研究取得的主要进展,包括重新厘定该区前南华纪古陆碎块的时空分布,获得与该区重大地质构造问题相关的新资料,提出对该区地壳构造格局、造山过程和成矿地质背景的最新认识,介绍了与该区地壳构造格局和成矿地质背景有关的需要进一步研究的重大地质构造问题。

This paper briefly states new developments in research and investigations on crustal tectonic framework of the Northern China orogenic regions financially supported by China Geological Survey in the last three years, which include the temporal and spatial distributions of re-confiruled Pre-Nanhuanian continental blocks in the region, new data on some major hot-debated geological issues, and new viewpoints on the crustal tectonic framework, orogenic processes and metallogenic geological settings. And finally, some major issues open to be further studied on the crustal framework and metallogenic geological settings in the region are listed.
