自从J·格莱戈利在1893年提出裂谷这一概态以来,人们对这一构造体的研究已取得了重大进展。事实上,就建造的意义来说,大型的裂谷盆地已成为地槽的同义语。因此揭示地史阶段中的裂谷构造,在理论上与实践上都有重要意义。笔者通过对分布在辽东—吉南地区的辽河群沉积建造特征的分析,提出辽河群沉积盆地的主体为一大陆型——陆间型裂谷。由于它在辽东发育较完正,可称辽东裂谷。辽东裂谷横亘于北纬40°20′～41°20′之间,宽约60～70公里,东自盖县向西经宽
Since J Grigori proposed the rift in 1893, significant progress has been made in the study of this structure. In fact, in the sense of construction, large rift basins have become synonymous with geosynclons. Therefore, it is of great significance both in theory and in practice to reveal the rift structure in the geological history. Based on the analysis of the depositional characteristics of the Liaohe Group distributed in the Liaodong-Ji’nan area, the author proposes that the main body of the Liaohe Group sedimentary basin is a continental-continental rift. Because of its development in the Liaodong more complete, can be called Liaodong rift. Liaodong Rift lies between 40 ° 20 ’~ 41 ° 20’ north latitude and 60-70 km wide. From east to west,
