被动陆缘的沉积建造由两套沉积物组成，一套是大陆解体的裂谷阶段所形成的陆相沉积物和双模式火山岩组合，另一套是稳定陆缘的复理石组合；岩装作用中基性岩类反应了物质直接源于上地慢的主要特点，并有部分受到地壳混染的特征；变质作用中高温低压环境主要发生在裂谷作用阶段，其特点反映了大陆解体过程中随着时间的增温和减压过程，而拆离伸展阶段则被脆性变形所代替。

笔者解释辉长岩构造就位年龄为891±13 Ma，在826±4 Ma受到前裂谷期岩浆活动的改造，并在764±10 Ma受到同裂谷岩浆活动的影响而发生亚固相热液蚀变。

By analyzing in detail the structural evolutionary history, from Mesozoic to Cenozoic, of different rift belts in western, northern, central and eastern Africa, the authors think that the Mellit area was on the northwestern shoulder of the South Sudan Rift. The rotation of the Mellit block toward northwest was the outward rotation of the northwestern shoulder of the South Sudan Rift during the rifting phase, and the rotation toward southeast was the inward rotation of the rift shoulder during the post-rift thermal sag episode.

经过详细分析非洲大陆西部、北部、中部和东部中新生代裂谷带的构造演化史后发现：Mellit地块实际上位于南苏丹裂谷带的西北裂谷肩上，该地块自晚白垩世初期至中新世初期，向NW方向倾斜是南苏丹裂谷带于裂谷化阶段造成的裂谷肩块体的向外旋转；该地块自中新世以来向SE方向倾斜是南苏丹裂谷带在后裂谷热沉降阶段造成的裂谷肩块体的向内旋转。

The basin evolution from the Cretaceous to the Palaeogene shows a complete process of rifting development, in which the Lower Cretaceous is theproduct of early rifting and the Upper Cretaceous and the Eogene represent the sediments of thermal subsidence in late rifting stage.

白垩纪—早第三纪盆地演化为一个完整的裂谷发育过程，下白垩统是裂谷早期断陷作用的产物，而上白垩统和下第三系则代表裂谷后期热沉降沉积。

Analogies are proposed between the East African Rift System and the Baikal Rift System with the Tharsis region of Mars, including the giant rift, Valles Marineris, Both regions are the result of mantle plume tectono-thermal activity that caused crustal uplift, volcanism and rifting. On Mars, we suggest that the subsurface ice, or cryosphere was liquefied as a result of igneous activity and or asteroid or cometary impacts, generating convecting cells of hydrothermal fluids.

将东非裂谷和贝加尔湖裂谷系统与火星Tharsis高原上巨大的水手大峡谷进行了对比，这些地区都是由地幔柱作用下构造－热液活动导致的地壳抬升、火山和裂谷作用。

However, the present-day's heat flow in the rift basin depends on the age of rifting.

裂谷盆地的地热随地质历史的演化逐渐降低，在裂谷拉张阶段具有很高的热流值，但现今的热流值则取决于裂谷发生的时间：中新生代裂谷仍保留较高的热流值且具有典型的&热幔冷壳&结构，而古裂谷现今的热流值较低。

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。
