| 摘 要： | 对中天山西段博罗霍洛山地区广泛发育的早古代代各纪地层的主要特征进行了简要描述。系统讨论了寒武纪、奥陶纪和志留纪的沉积相类型及特征。对中天山地区沉积和构造发展进行了分析，结果表明在早古生代时期，本区具有裂陷带性质，并将裂陷带的演化归纳为坳陷、裂陷和闭合三个发展阶段。

| Abstract: | The Early Palaeozoic distributes extensively and completely in the Keguerginto BOlhinur mountain region of the western part of middle Tianshan. The major stratigraphicfeatures of the Early Palaeozoic are describe. The types and characteristics of sedimen taryfacies on Cambrian. Ordovician and Silurian are discussed.Based on analysis of thesedimentary and tectonic evolution in middle Tianshan.the Bolhinur mountain region has thecharacteristics of Aulacogen.Its development can be divided into three stages of depressionstage,rifting stage and closing stage. |
