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。

Based on sequence stratigraphy theory and method,and the comprehensive analysis of cores,seismic and logging data,the depo-sitional filling styles of Palaeogene rifting period in Yuanyanggou area of west Liaohe Depression were divided into 4 second-order sequences and 8 third-order sequence s.

运用层序地层学的理论与方法，综合分析岩心、测井以及地震等资料，将辽河坳陷西部凹陷鸳鸯沟地区古近系裂陷期的沉积充填划分为4个超层序和8个三级层序。

Since the plate tectonic theory was introduced into China in 1970's, aulacogen has been considered in the area of Helan Mountain in Ordos Basin by some geologists. It is believed that Helan Mountain, Qinling and northern Qilian area were at the stage of rifting development from Mid-Neoproterozoic to Early-Mid Cambrian, and that Qinling, northern Qilian, Helan Mountain formed a trifurcate rift valley system.

自19世纪70年代板块构造理论引入中国后，一些学者把拗拉槽一词赋予了鄂尔多斯盆地西缘贺兰山地区，并认为贺兰山、秦岭、北祁连中新元古代至早中寒武世为裂谷发育阶段，秦岭、北祁连、贺兰山构成了三叉裂谷系。

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。

The results are shown as below.1 Tectono-thermal evolution: The history of the Songliao basin is divides into four stages, high-temperature doming and extension, high-temperature rifting, low-temperature depression, and low-temperature shrinkage. Numerical simulation of mechanical process shows that the basin appeared in the early- to late- Jurassic as a result of rapid low-angle subduction of the Pacific plate towards the northwest, of movement of the Siberian block towards the southeast, of many other influences such as internal thermal stress in the mantle, gravitational force, stress of phase transition, etc. Both the Pacific plate and the Siberian block slowed down in the early Cretaceous, and almost stopped in the middle Cretaceous with the rapid decrease of abnormal heat in the mantle below.

盆地构造热演化力源机制数值模拟研究表明：早、中侏罗世至晚侏罗世晚期，盆地演化主要是太平洋块体向北西方向以低角度快速俯冲和西伯利亚块体向东南俯冲共同作用的结果，同时也与地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和上覆块体绝对运动的作用有关；早白垩世早期至早白垩世中期，来自东部太平洋块体俯冲作用的减弱，而这一时期影响盆地演化的主要力源是地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和来自西伯利亚块体俯冲作用；进入早白垩世晚期至晚白垩世早期，由于双重俯冲带中西侧俯冲作用带基本停止活动，而本区地幔热能的快速衰减则控制盆地的构造热演化；晚白垩世晚期以后，太平洋块体活动加强和地幔热运动是影响盆地演化的主要动力。
