Most of areas are not deposited until benxi stage , except for helan aulacogen , where the deposit began in jingyuan stage 除贺兰拗拉槽北部从靖远期开始沉积外，绝大部分地区从本溪期才开始沉积。

Yanqi basin , located in the northern wing of the " v - type " thrust - fold belt , is related to the reversion of the kuluketage aulacogen 因此库鲁克塔格裂陷槽的构造反转是焉耆盆地构造变形的主要力学来源。 2 、描述了盆地内的构造样式。

Beginning form relation of basin - mountain , the tectonic evolution and the petroleum system and pool - forming process have been studied with the integration of structural physics modeling , balance profile reversion and other new testing technology . the main innovative achievements of the dissertation can be summarized as following : 1 . on the basis of comprehensive analysis of yanqi basin relationship to tianshan orogenic belts , it was suggested that kuluketage faulted - upheaval was an aulacogen in early paleozoic , which undergone multiple opening - closing along with tianshan orogenic belts , and suffered extensively compressing in late hercyhian cycle and formed a " v - type " thrust - fold belt 论文总的指导思想是以现代石油地质理论为基础，以整体、动态、系统、综合分析为原则，以成盆?成烃?成藏研究为主线，运用正、反演相结合的残留盆地油气成藏系统评价思路，采用构造物理模拟、平衡剖面复原和多种测试新技术，从盆山耦合关系切入，研究含油气系统成藏要素及其相互作用过程，探讨油气成藏主控因素和油气分布的有序性，取得如下创新性成果和认识： 1 、系统分析了焉耆盆地形成演化与天山构造带的关系，提出盆地南侧的库鲁克塔断隆在早古生代为一大型裂陷槽，之后随着天山构造带的演化，经历了多次开合运动。

The sedimentary formation can be summarized as rift bay filling sequence , epicontinental sea filling sequence , offshore debris lake basin sequence and inner continental lake basin sequence . a framework of sequence stratigraphy for the upper palaeozic strata is established in the area . the helan aulacogen of upper carboniferous in the west margin of ordos can be divided into 12 sequences , and most of the upper palaeozoic strata in the area can be divided into 15 sequences 本文对研究区内上古生界进行了层序地层学探讨，将本区沉积建造概括为裂陷海湾充填层序、陆表海充填层序、近岸碎屑湖盆层序和内陆湖盆层序，建立了研究区上古生界层序地层学格架，西缘贺兰拗拉槽上石炭统划分为12个层序，本区大部分地区上古生界可划分出15个层序，并全面地概括了层序演化各阶段的具体特征。

Some conclusions are listed as follows : the plateform cover cap of ordos basin and its circumference areas can be divided into five tectonic sequences . the tectonic evolution of ordos basin can be classified in six stages : the basement formation phase ( from archeozoic to paleoproterozoic ) ; the aulacogen phase ( from mesoproterozoic to neoproterozoic ) ; the north china continental sea phase ( from sinian to early - paleozoic ) ; the north china intracratonic depression phase ( from late - paleozoic to early mesozoic ) ; large ordos inland basin phase and the formation of independent ordos basin ( mid - late mesozoic ) ; fault basin phase around the ordos basin ( cenozoic ) 通过研究有以下成果及认识：鄂尔多斯盆地及其周缘地区沉积盖层可划分为五大构造层序，盆地的形成和演化分为六大构造阶段：太古代至古元古代基底形成阶段、中新元古代克拉通内裂陷槽或坳拉槽演化阶段、震旦纪?早古生代华北陆表海盆演化阶段、晚古生代?早中生代华北克拉通坳陷演化阶段、中生代中晚期大鄂尔多斯内陆盆地演化阶段及独立鄂尔多斯盆地的形成、新生代周缘断陷盆地演化阶段。

A large amount of data of the latest regional geoglogy and the latest correlation data of layers and rock formation have been quoted , and a description of distribution of crystalline basement , formation , evolution as well as the distribution characteristic of the fracture belt of ordos basin have been made in this paper , and the paper also pointed out that the g - layer which lies between the base of the basin and tg reflector , is the extension of basinward of guandaokou of jixian system . the layer of changcheng system and jixian system , which had been divided before , can be correlated with the exposed huangqikou group and wangquankou group in helan mountain , and divided into qingbaikou system . so , the paper denied the viewpoint of the existence of aulacogen in hutuo period and middle proterozoic in this basin 文中引用了大量最新的区域地质资料和最新的地层、岩系划分对比资料，对鄂尔多斯盆地结晶基底的岩系分布、形成、演化以及断裂的展布特征进行了描绘，并指出盆地基底与tg反射层之间的g层是蓟县系官道口群向盆地的延伸，盆地中原划分的长城系、蓟县系地层可以和贺兰山出露的黄旗口组、王全口组对比，亦划归青白口系，从而否定了鄂尔多斯盆地存在滹沱期坳拉谷和盆地中有中元古坳拉谷发育阶段的看法。
