摘要
通过对塔里木、准噶尔、伊犁、昆仑山等地区古地磁研究获得了大量数据,结合磁性地层、古生物、沉积相等综合分析,对塔里木地块构造演化、新疆晚古生代构造分区划分、伊犁地块、天山板块等几个地质构造问题进行了探讨.
Through perrenial study of paleomagnetism, the polar wandering curve for Tarim block from Late Paleozoic to Tertiary and paleolattitude of each epoch were obtained. Based on this study the boundaries between Jurassic-Cretaceous system.Permian-Tertiary system and Devonian-Sinnian system were classified. The study of magnetic strata were also Combined with that of paleobiology and sedimentary facies, ect. to approach the
tectonic evolution of Tarim block, the division of tectonic region of late Paleozoic and several geologic tectonics such as Hi block and Tianshan plate.
