| 摘 要： | 中国吉林东部与朝鲜半岛北部地区对比研究,无疑对揭示朝鲜半岛的地质属性、中朝板块北缘东延及演化有着重要的贡献。针对中国吉林东部延边地区和朝鲜咸北地区的晚古生代地层进行化石组合、沉积特征、基底性质以及岩浆序列等方面的对比研究认为:朝鲜二叠纪鸡笼山腕足动物群与中国北方二叠纪哲斯腕足动物群有明显差异,与吉林地区范家屯组,尤其是延边地区庙岭组有较强的可对比性;中国吉林—延吉褶皱带和朝鲜咸北地块均以元古宇为基底,没有太古宙岩石出露;在晚古生代期间,中国吉林东部—延边地区和朝鲜咸北地区沉积环境、岩浆活动相似;朝鲜咸北地块和狼林地块的边界断裂——输城川断裂带应与华北地块和吉黑造山带之间缝合线的东端—古洞河断裂相连接,吉黑造山带东部地块和朝鲜咸北地块在晚古生代时期应处于同一个大地构造单元。

| Abstract: | The comparative study of the eastern Jilin,China and North Korea areas will undoubtedly contribute to revealing the geological properties of the Korean Peninsula,as well as the eastward extension of Sino-Korean Plate and its tectonic evolution.In this paper,comparative study of the Late Paleozoic strata in Yanbian region,Jilin in the Eastern of China and in the Hambuk region of North Korean Peninsula include fossil assemblages,sedimentary characteristics,the properties of basement rocks and magma series.It is suggested though the Jilongshan permian brachiopod fauna in Korea and Zhesi permian brachiopod fauna in North China are quite different,the Jilongshan Permian brachiopod fauna can be significantly correlate to the Fanjiatun Formation in the Jilin,especially the Miaoling Formation in the Yanbian region.In addition,the basement strata and rocks developed in both of the Chinese Jilin-Yanji fold belt and in the North Korean Hambuk massif are of the Proterozoic age,and the Archean rocks is not exposed;in the Late Paleozoic,the sedimentary environment and magmatic activity in the eastern Jilin-Yanbian region in China is similar to those in Hambuk region in the North Korean Peninsula;moreover,the Susongchon fault,a boundary fault between of the Hambuk massif and Rangnim massif in the Korean Peninsula,is connected to the eastern end of the suture line between of the North China block and the Jilin-Heilongjiang orogenic belt,the so called Gudonghe fault zone.Therefore,the eastern part of Jilin-Heilongjiang orogenic belt and the North Korea Hambuk massif should be belong to the same tectonic unit in the Late Paleozoic period. |
