塔里木盆地古生代古地磁结果及其构造地质意义

PALEOZOIC PALEOMAGNETIC RESULTS AND THE TECTONIC SIGNIFICANCE OF TARIM PLATE

发表了塔里木盆地奥陶纪、志留纪、泥盆纪、石炭纪、二叠纪古地磁新数据，大部分数据通过了剩磁分离或一致性检验、倒转检验、极性对比检验、褶皱检验和烘烤检验．根据新的数据绘制了塔里木板块古生代视磁极游移曲线（ＡＰＷＰ），探讨了塔里木板块构造演化规律，强调了奥陶纪末的加里东构造运动及早海西构造运动的重要意义．

The new paleomagnetic data of Early Ordorivian,Silurian, Devonian,Carboniferious and Permian from the Tarim plate have been documented.Most remanences were undergone stability tests,suchas reversal test, baked contacted and fold test.The paleozoic APWP of Tarim plate has been established based on the averaged remanences of the relevent ages. The early Ordorivian Calidonian and the Hercian movements were emphysised on the tectonic evolution of the Tarim plate.
