| 摘 要： | 根据秦岭及邻区二叠纪古生物地理和古地磁数据分析，以活动论观点为指导，探讨了秦岭的海盆特征。２４组古地磁数据和珊瑚、腕足和类的古生物地理说明二叠纪的秦岭海位于低纬度区并以不同的速度向北不断移动。早二叠世东、西部的海盆定分别是１０００ｋｍ和２０００ｋｍ。

| Abstract: | The Permian plate tectonics and basin evolution of the Qinling Belts was discussed based on study of paleomagnetism and paleobiogeography, which include 24 groups of paleomagnetic data and paleobiogeography of corals, brachiopods and fusulinids. Data show that the Qinling Sea was located in low paleolatitudes and underwent northward migration with different velocities in various Permian epochs. The widths of its eastern and western parts were about l,000 and 2,000 km respectively during Early Permian. |
