| 摘 要： | 中、上扬子区石炭纪继承了加里东运动后的构造格局,滇中前寒武纪基底隆起区——康滇古陆(Ⅰ_1~1)不断向东扩大,与滇东早奥陶世后隆起区(Ⅰ_1~2)归拼。由于川中早志留后隆起区(Ⅰ_1~8)徐徐上升,它把川东鄂西泥盆世后隆起区(Ⅰ_1~(11))、以及武当、大洪山(Ⅰ_1~4)、湘西武陵山(Ⅱ_1~5)、雪峰山(Ⅱ_1~6)前寒武基底隆起区基本连在一起,从而使中、上扬子地块上的“中、上扬子古陆”雏形大致形成。晚泥盆世扬子古陆北缘被动大陆边缘盆地等与石炭纪早期基本相仿。湘、桂交界处,以龙胜-永福断裂为界,其西南为右江张性被动大陆

| Abstract: | The Carboniferous tectonics inherited the post-Caledonian tectonic framework in the Upper and Middle Yangtze regions, southern China. Six types of tectono-sedimentary basins are recognized in accordance with tectonic characteristics, sedimentary formations, sedimentary facies differences, biologic assemblages, basement structures, magmatism and associated mineral resources, They are:Type a-the passive continental margin basin with a unilateral steep slope; Type b-the shallow stable intracratonic basin; Type c-the uniclinal steplike extensional basin; Type d-the extensional basin with intracontinental rifts; Type e-the uniclinal relic trough basin, and Type f-the intracontinental basin. As a reference, the present paper has provided the significant geologic records for the study of the tectonic evolution and basin-controlled mineral resources in southern China. |
