| 摘 要： | 郯—庐断裂带纵贯中国东部,规模巨大,长期、多次活动,对该区的地质发展,岩浆活动和矿产的分布均起到重要的控制作用。目前,地学界对其北段和中段的存在已无异议,但南延问题仍处于众说纷纭的争论局面。笔者通过对郯—庐断裂带基本地质特征的认识,并与湖南、江西存在的深大断裂进行对比,同意前人将郯—庐断裂带与赣江断裂相连的意见,认为它南延进入湖南的可能性不大。

| Abstract: | The Tancheng-Luzhou fault zone, stretching across eastern China from north to south, is tremendous in dimension and freqently active in long term, which played an important role in controlling the geological development, magmatic activity and distribution of mineral resources. Up to now, there is no objection about the existance of its northern and middle parts among the scholars in geologic circle, but opinions about its southward extension still vary. The author discussed the basic geologic features of Tancheng-L,zhou fault zone and compared with the deep magafaults in Hunan and Jiangxi provinces, agrees the former's opinion that the Tancheng-Luzhou fault zone extends southward and connects Gangjiang fault zone. It is hardly possible that it extends southward into Hunan province. |
