新疆伊犁地块早二叠世的古地磁结果

作者对新疆伊宁地区早二叠世地层的古地磁进行了研究。结果表明:1)早二叠世时,伊犁地块已增生到欧亚大陆之上并同塔里木地块连在一起;2)早二叠世后伊犁地块相对欧亚大陆北部稳定区发生过大规模顺时针旋转运动。

PALEOMAGNETIC STUDIES OF EARLY PERMIANSTRATA IN THE ILI LANDMASS,XINJIANG

Researches have been made on paleomagnetism of Early Permian stratain Ili area, Xinjiang, and the results indicate that: 1) during Early Permian,the Ili landmass was stuck on the Eurasian continent through accretion andlinked with the Tarim landmass; 2) after Early Permian, the Ili landmassexperienced large-scale clockwise rotation relative to the northern stableregion of the Eurasian continent.
