We have concluded five key tectonics geologic characteristics of Chinese foreland basins based on the study of the sedimentary infill, tectonics evolution, tectonic dynamics, spatial location distribution and structural deformation geometry.(1) The foreland basin is the superimposition of the compression sedimentary stratigraphic sequence with the extension basin, and the foreland basin includes underlying rift basin and upper dustpan flexure deposited basin.(2) The foreland thrustfold structural deformation has occurred four times since the Protozoic, in the Late Caledonian, Late Hercynian, Indosinan and Late Himalayan, respectively.(3) The foreland basin developed based on the control of two factors that are the basin basement collaged by many small plates or terrains and the rejuvenation of ancient orogenic belt, so the foreland basins or foreland thrusts are located in front of ancient orogenic belt.(4) The foreland basins and the rejuvenation of ancient orogenic belt make up a giant basinmountains system resulting from the distant effect of IndiaEurasia collision, which is located on the outer circle of Tibet Plateau, so the thrust deformation intensity, basin deposition range and coupling between orogenic belt and basin changed from strong to weak as from interior to outer circle of Tibet Plateau.(5) There are many structural styles of the thrust and fold belt in different basins, such as brittle behavior faultrelated fold, ductile behavior basementinvolved structure, basementinvolved faultrelated fold, and salt structure.

在综述前人认识的基础上，笔者通过对中国前陆盆地的构造演化历程、沉积充填特征、构造成因及其空间分布规律、构造变形特征等的研究，提出了中国前陆盆地构造地质发育的5个主要特征：(1)两种不同性质的原型盆地发生正反转的叠合性，即挤压构造下作为&本体&的前陆层序与拉张构造下作为&基础&的裂谷、断陷盆地之间的叠置；(2)显生宙以来中国大陆先后发生了4期前陆冲断构造演化的多期性，它们分别是加里东晚期、海西晚期、印支期和喜马拉雅晚期；(3)基于小克拉通基底拼贴后在造山带前缘复活再生的继承性，即统一拼合大陆内部的构造变形导致古造山带的复活，在古造山带边缘发育新生代前陆盆地或前陆冲断带；(4)在空间分布上受环青藏高原巨型盆山体系控制发生陆内变形的系统性，在环青藏高原巨型盆山体系内构造变形强度、盆地沉降幅度、盆山耦合程度等从内环向外环依次降低，从古造山带向克拉通方向构造变形强度依次降低，构造变形样式逐渐简单、构造变形时间依次变新；(5)前陆冲断带的构造样式由于受边界力学条件和沉积地层介质作用而具有多变性，存在沉积盖层内脆性变形的断层相关褶皱、造山带前缘韧性变形的基底卷入构造、与走滑构造相伴生的基底卷入的断层相关褶皱、盆地内部塑性变形的盐构造。

Applying contrarian strategy of Lo,Mavkinlay(1990), the decomposition of Jegadeesh,Titman(1995) and introducing turnover shock into the contrarian strategy, we find there are statistically significant profits for short-term contrarian strategy in the China stock market.

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。

In Songliao basin, the stronge tectonic inversion occurred in the Late Mingshui Formation, and during the declining of compressive force from the SSE to the NNW, the reactivation of basement faults formed positive inversion faults; released from thermal fluid diapirs, CO2 was migrated upward and then accumulated in inversion structural belts; as the development of fault-style inversion tectonics in the southern part is better than the northern part, and the western is better than the eastern part, CO2 is richer in the south than in the north, richer in the west than in the east in Songliao basin.

松辽盆地强烈的构造反转发生在明水组末期，挤压应力自南南东向北北西方向衰减的过程中，基底断裂复活形成正反转断层，CO2气从热流底辟体中脱出上运而聚集在反转构造带上，断层式反转构造南部比北部发育，西部比东部发育，因此松辽盆地南部比北部、西部比东部CO2气更富集。

After the phase inversion point,the dynamic rheological parameters increase greatly with adding water.

实验结果表明，体系在相反转点前表现为牛顿流体行为，粘度几乎不变﹔相反转点时，体系粘度增加幅度很小，体系的有关动态流变参数(剪切储能模量、损耗模量和复数粘度)均出现极小值，将此归于局部连续水相的润滑作用﹔进一步加水，体系的动态流变量增加，意味著相反转在相反转点后仍在继续进行。
