| 摘 要： | 博格达山横亘于准噶尔盆地和吐—哈盆地之间，关于博格达山的隆升时间一直是一个具重要意义而又长期争议的问题。综合分析前人及研究区资料认为:早石炭—中二叠世博格达地区以拉张环境为主；在晚二叠—早三叠世，吐—哈盆地台北凹陷沉积物的粒度、分布、形态、成分变化等特征以及地层接触关系表明博格达山初次隆升；中侏罗世，台北凹陷的沉积相、ZTR指数以及砂岩岩屑成分在时间上和空间上的变化，表明西山窑组晚期博格达山再次隆升，并向吐—哈盆地提供物源，但喜山运动期间博格达山隆升幅度最大，铸成了现今的盆山格局。

| Abstract: | The Bogda Mountain located between Junggar basin and Turpan-Hami basin.Its uplift time has been debated for a long time and is of important geotectonic significance.Based on the information of predecessors and the study area,it is considered that the Bogda area was mainly in extensional environment between Early Carboniferous to Middle Permian;in later Pernian-early Triassic period,the particle size,distribution,morphology,composition changes of Turpan-Hami Basin sediments and stratigraphic contact relation... |
