摘要: 以板块构造学说为指导，以大陆动力学理论研究大陆块体离散、会聚、碰撞、造山的大陆动力学过程为主线，划分了陆块构造演化阶段.辽宁省由胶辽陆块、晋冀辽陆块2个Ⅰ级构造古地理单元组成；Ⅱ级构造古地理单元3个，即辽东陆内、燕辽裂谷、燕辽陆内；Ⅲ级构造古地理单元11个；Ⅳ级构造古地理单元14个.利用沉积岩建造组合与构造古地理单元时空结构演化关系，为研究辽宁省大地构造环境演化提供较系统的基础地质资料.Abstract: Guided by the theory of plate tectonics, the dynamic processes of continental block divergence, convergence, collision and orogeny are studied to divide the tectonic evolution stage of continental blocks in Liaoning Province. This region is composed of multiple paleogeographic tectonic units, including two first-order units (Jiao-Liao landmass and JinJi-Liao landmass), three secondary-order units (Liaodong intracontinent, Yanliao rift and Yanliao intracontinent), eleven third-order units and fourteen fourth-order units. The relationship between the comosition of sedimentary rock formation and the time and space structural evolution of tectonic paleogeographic units provides basic geological data for the research of the tectonic evolution environment in Liaoning Province.
