依据古生物资料,探讨新疆古生代相关块体的亲缘关系和缝合时代。①早古生代不同省区动物群先后多次入侵哈萨克斯坦板块,表明中、晚寒武世和晚奥陶世哈萨克斯坦板块靠近塔里木、中朝和华南—东南亚板块;早古生代其余时期它接近西伯利亚板块。②早古生代,伊犁地体与塔里木板块亲缘,因为它的寒武纪三叶虫属于东方动物群的东南型,奥陶纪笔石是真正的华南型,缺乏志留纪的Tuvaella群落。中、晚泥盆世,广泛分布于塔里木、华南—东南亚等板块的标志化石Stringo-cephalus、Yunnanella、Yunnanellina在该地体遁迹,说明中泥盆世之前它远离塔里木板块。早二叠世晚期,它接近哈萨克斯坦板块,导致安加拉植物群入侵。推测托克逊—雅满苏地体与伊犁地体有相似的经历。③北山地区与伊犁地体、塔里木板块库鲁
According to the paleontological data, the genetic relationship and the stitching age of Paleozoic related blocks in Xinjiang are discussed. ① Early Paleozoic fauna in different provinces and autonomous regions invaded Kazakhstan plate multiple times, indicating that the Mid-Late Cambrian and Late Ordovician Kazakhstan plates are close to the Tarim, China and North Korea and South China-Southeast Asia plates. In the rest of Early Paleozoic, it approached the Siberian plate . Early Early Paleozoic, the Ili terrane was related to the Tarim plate because its Cambrian trilobite belonged to the southeast of the Oriental fauna. Ordovician petrofabrics are truly southern China and lack the Silurian Tuvaella community. In the middle and late Devonian, the fossilized Stringo-cephalus, Yunnanella and Yunnanellina, which are widely distributed in the Tarim, South China-Southeast Asia plateau, have disappeared in this area, indicating that it was far away from the Tarim plate before the Devonian. In the late Early Permian it approached the plate of Kazakhstan, leading to the invasion of Angara flora. It is speculated that the Tokchon-Yaman Su terrain has a similar experience with the Ili terrane. ③ Beishan area and the Ili terrain, Tarim plate Kuru
