大凌河—辽河海底谷系(辽河古河道),地质工作者对它曾有过不少论述。本文仅对谷系的位置、形态、形成、发育及其与构造和沉积的关系作进一步研究。 一、谷系的位置与谷地的形态 大凌河—辽河海底谷系位于辽东湾东部,是由大凌河海底谷地和辽河海底谷地组成的一组谷系。大凌河海底谷地首端位于大凌河口外,与大凌河口相对,并向东南延伸。辽河海底谷地始于辽河三角洲外,与辽河口相对,向东南延伸。两谷地平行于辽东湾东坡,蜿蜒曲折、相 Daling River - Liaohe sea valley system (Liaohe ancient river), geologists have had a lot of discussion on it. This article only further studies the location, morphology, formation and development of the valley and its relationship with the structure and sedimentation. First, the valley position and valley shape Daling River - Liaohe sea valley system is located in the eastern part of Liaodong Bay, is composed of a group of valley valley and the Liaohe sea valley. The first end of the Dalingheitang Valley is located outside the Dalingkou River, opposite to the Dalingkou River and extending to the southeast. Liaohe sea valley began in the Liaohe River Delta, and the Liaohekou relative to the southeast extension. Two valleys parallel to the east slope of Liaodong Bay, twists and turns, phase
