试论秦岭──大别山──胶南隆起──临津江褶皱带及其周缘地区的大地构造属性

具有统一发展史和构造属性的中国华北－东北南部－朝鲜北部地区构成了东亚地区较大的稳定区－中朝古陆，大量的研究工作使得其内部及其南部的大地构造格局逐渐明朗化，作为中朝地台与其南侧的稳定区－扬子地台之间的过渡带－秦岭地槽的构造轮廓、构造属性、发展史也得到了进一步的厘定。由于郯庐断裂的影响，加之研究程度的限制，在该断裂以东，中－朝古陆与扬子地台的构造关系及其间过渡带－秦岭地槽的东部延伸问题一直困绕着人们，加之朝鲜半岛的构造复杂性及黄海地区的资料缺乏，致使中－朝古陆南缘的大地构造格局成为亟待解决的重大构造地质问题。古生物资料的对比研究表明：沿着秦岭－大别山－南朝鲜的汉城分布着一系列的古陆隆起，其分隔了北部和南部的两个海盆（中朝海盆和扬子海盆），使得两个海盆的古生物交往受到了阻碍，从而导致了南北两侧的古生物差异，尤以早古生代最为明显，至晚三叠世之后南北两侧的古生物面貌趋于相似。近期研究成果表明：胶东地区曾有过中晚古生代地层的沉积，而在朝鲜松林地区也发现了中晚古生代地层，这进一步说明了胶南隆起北部拗陷带、南黄海盆地及朝鲜汉城隆起北侧的临津江坳陷在中晚古生代呈经历了相近的大地构造发展史。沿秦岭－大别山－胶南隆起－临津江褶皱

ESSAY ON THE TECTONIC ATTRIBUTE OF QINLING-DABIE MOUNTAIN-JIAONAN UPLIFTRIMJIN-GANG FOLD BELT AND ADJACENT REGIONS

Based on the similarities and differences in stratigraphic paleontology,metamorphic complexes of Archaeozoic-Early Proterozoic Era,systems of crystalline rocks of Early Precambrian,evolutional features of intracontinenta1(intercontinental)rift and caprocks , the authors probe into the tectonic attribute of Qinling-Dabie Moun-tain-Jiaonan Uplift-Rimjin-gang Fold BeIt and adjacent regiOns,and set forth the tec-tonic corresponding correlation between North China Platform-Rangrim Massif(Chi-na-Korea Paleocontinent )and Yangtze Platform-Kyonggi Massif(Yangtze-Kyonggi Paleocontinent)and the different motions between them. Combining the gravity-magnetic anomaly,glaucophane-schist,eclogite and other evolutional features of granitic rocks,the authors think that China-Korea and Yangtze-Kyonggi Paleocontinents collided with each other and then combined together along Qinling-Dabie Mountain-Jiaonan Up lift-Rimjin-gang Fold Belt respectively in the last period of Proterozoic and in Late Tri-assic.
