根据新疆西北部伊宁果子沟、艾比湖及和布克赛尔等地的早古生代地层剖面，对这一地区寒武系、奥陶系和志留系的岩石地层单元和生物带作了修订，特别是重新修订了奥陶系的新二台组和风沟组，并建议取消塔勒基河组。对下古生界各系的生物带作了较大的修订，并基于此对各纪地层作了划分和对比。根据地层的发育特征和各门类生物地理分布，认为新疆西北部在早古生代属于哈萨克斯坦古板块的东延部分。 According to the Early Paleozoic stratigraphic sections of the Gansu Province, Yining Guozigou, Lake Aibi and Hebukesel in the northwestern part of Xinjiang, the lithostratigraphic units and biozones of the Cambrian, Ordovician and Silurian in this area were revised , In particular, reworked the new Ertai and Erhugou formations of the Ordovician and proposed the abolition of the Taleji River Formation. Great changes have been made to the biological belts of the Lower Paleozoic strata, and based on this, the stratigraphic stratigraphies have been divided and contrasted. According to the stratigraphic development characteristics and the biogeographical distribution of all kinds of strata, it is considered that the northwestern part of Xinjiang belonged to the eastward extension of the old plate of Kazakhstan in the Early Paleozoic.
