| 摘 要： | 作者通过对准噶尔地块的岩脉采样的古地磁研究以及大量地质资料,确认了准噶尔地块在早二叠世位于北纬35°,与塔里木地块、哈萨克斯坦地块及西伯利亚基本上在同一纬度带中,作为劳亚大陆的一个组成部分,作者并对该区自早二叠世以来的构造变动作了分析.

| Abstract: | On the basis of paleomagnetic study of samples collected from dykes inJunggar massif and large quantities of geological data, it is confirmed thatJunggar massif was located 35° north latitude in Early Permian, lying basically in the same latitude zone as Tarim massif, Kazakhstan massif and Siberia andserving as a component part of Laurasis continent. The authors have also madean analysis of tectonism in this area since Early Permian. |
