| 摘 要： | 着重论述了朝鲜北西部五条主要断裂的活动性、简要地叙述了这些断裂的概略特征,认为北东向的鸭绿江东支断裂、清川江断裂为中、晚更新世有活动,早更新世有明显活动的断裂;北西向的载宁江断裂为中更新世有活动,早更新世有明显活动的断裂;在北西西向断裂中,长林断裂为早更新世—上新世活动断裂,南江断裂活动时代不详。其活动性最明显的为鸭绿江东支断裂和载宁江断裂,次为清川江断裂和长林断裂,再是南江断裂。最后,还讨论了这些断裂的形成与演化。

| Abstract: | The discussion in the paper put on activity of five main faults in the Northwest Kore-a. Their features are as follows: East branch of Yalujiang fault and Qnghchuanjiang fault inthe direction of Northeast had a little activity in middle-and later-pleistocene, generatedobvious activity in early-pleistocene; Zhainingjiang fault in the direction of Northwest wasa little active in middle-pleistocene and evident in early-pleistocene; Changlin fault ofnorthwest by west is a early-pleistocene and pliocene one; but still the activity of Nan-jiang fault is not clear. Anong others East branch of Yalujiang fault and Zhainingjiang faultare the most active. |
