The south-north united tectonic environment and tectonic pattern does not exist. The east-west trend thrusting Nappe structure of Majiatan and Hengshanpu can not represent the whole western margin of Ordos. The attempt to solve the regional tectonic problem with simple tectonic pattern is against the geological theory, especially in the Helan Mountain region.(2) After the geochemical data analysis of Ruqigou basalt in Helan Mountain, the article illustrates that it belongs to continental rift basalt which appeared in the late-Triassic and early middle Jurassic. Meanwhile the article states that the region is located in the rift environment of an extension background and Rudigou is located in the central part of the rift.(3) The article illustrates that the western ridge of Helan Mountain used to be on a slope and topography slowly declines from west to east after analysis and demonstrations of the distribution under XiaoSongshan bedding fault. Through comprehensive analysis of the no-strong deformation and bedding fault features, the article states that the Xiaosongshan bedding fault used to be gravity slip detachment structure and it represents the extension from the east to the west. Based on the above and analysis and demonstrations of isotope age and track datting, the article illustrates that the ? characteristic of the east of the western ridge of Helan mountain being higher than the west is the result of its late tectonic reverse.(4) Through comparison between Rujigou region Mesozoic Era late Triassic period-early and middle Jurassic period deposit and that of Ordos Basin and the analysis of the late Triassic period extension and early -middle Jurassic Period deposit povenevance it sets forth that during the period, Rujigou region was part of a large deposit basin which was closer to the northern povenevance and farther from the western povenevance.
以马家滩和横山堡为代表的东西向逆冲推覆构造模式,在整个鄂尔多斯盆地西缘不具有全区统一性,那种试图用单一的构造模式解决本区构造问题的尝试,无疑是与地质实际相悖的,尤其是对贺兰山地区;(2)通过对贺兰山汝箕沟玄武岩地质地球化学测试分析,提出其为大陆裂谷玄武岩,其形成时代为晚三叠—早中侏罗世,并通过该玄武岩的稀土和微量元素的测试分析资料进行了多种判别分析,最终确定该区处于拉张背景下的裂谷环境,汝箕沟地区大致处于当时裂谷的中心部位;(3)通过对小松山断层面之下地层分布规律,结合其变形特征的分析论证,认为当时贺兰山西麓处于一个由东向西平缓抬高的斜坡环境,并通过小松山断层面之下地层的非强烈变形及顺层断层特征等的综合分析,认为贺兰山西麓的小松山断层原本是一重力滑覆断层,它代表了近东西向的拉张,在此基础上通过裂变径迹测试资料的分析论证对其做了进一步认定,目前贺兰山西麓东高西低的剖面特征是该区后期构造反转的结果;(4)通过对汝箕沟地区中生代晚三叠世—早中侏罗世沉积与鄂尔多斯盆地内部的对比、晚三叠世延长组及早中侏罗世沉积物源和水流向分析,认为该时期汝箕沟地区为一更靠近北部物源,而距西部物源明显较远的沉积环境,是一更大型沉积盆地的一部分。

The orogenic strata have following characteristics: During the subduction and intracontinental orogeny, the strata experienced dramatic tectonic migration and mixing, resulting in various tectonic features. A short sequence usually composed of tectonic slices of various origins, times, deformations and metamorphisms, and scales. The original sequence was badly destroyed. The extant fragments of orogenic belt usually took form as melanges, especially the accretion complex wedge generated in subduction zone, which is contrary to the Law of Superposition. The original location of the accretion is also contradicted with the Law of Original Horizonality, because the accretion is oblique with high degree. Marine rocks, volcanic rocks of continental margin and metamorphic rocks were well-developed in the orogenic belt, especially ultra-basic, basic rocks were wide spread and were intensely metamorphosed, accompanied by metamorphic slices returned from hundred kilometers underground with ultra-high pressure and magma movements during syn-orogeny and post-orogeny, thus formed the colorful landscapes.
