摘要
东北地区在现今地质构造上属滨太平洋构造域,前中生代属于古亚洲洋构造域.在近年来地质调查研究的基础上,概要分析了该区区域地层划分对比争议、火成岩岩石组合及形成年代格架、大型变形构造时空演化特征、大地构造格局等.通过加强地质调查研究对这些问题逐步加以解决,将为全区资源与环境区划、勘查与开发更新基础地质依据,并将东北地区地质研究推向国际地学前沿.
Northeast China is situated in the west of circum-Pacific tectonic domain, formerly belonged to the Paleo-Asian tectonic domain in pre-Mesozoic era. Some important issues on the basic geology in the area are still left for further geological survey and research, including regional stratigraphic division, igneous rock assemblages and geochronology, temporal-spatial evolution of large-scale deformation structures, tectonic patterns and so on. The solution for above mentioned problems will not only provide a basis for the resources and environment planning, exploration and development in NE China, but also promote the geological research in Northeast China to international level.
