禾青井动水位对断层蠕动与慢地震过程的响应初析

以湖南禾青井深井水位观测的异常图象为例进行定性分析，发现动水位观测有可能直接反映出断层的滑动或断层的慢地震过程，前者可能为地下水物理参量的观测与研究提供亲折思路，后者则可能对震源物理学的发展和地震预报水平的提高具有特殊的意义。     

成都平原的形成与演化

成都平原是位于青藏高原东南侧前缘的第四纪压陷盆地，东西两侧分别被龙泉山和龙门山所限。研究表明，成都平原的第四纪断陷作用从大邑－彭县－绵竹隐伏断裂和浦江－新津－成都－德阳断裂所夹的北东向断块的为民陷开始，然后向东西两侧扩展。不同断裂在不同时代的逆冲运动对成都平原的形成和演化起重要的制约作用。     

井孔变径与井水位的固体潮效应

根据多孔介质渗流理论和弹性理论，在井孔变径条件下，得出水井含水层系统对潮汐信号响应的偏微分方程，认为井径变化相当于改变了井水柱的有效高度，从而影响了水井含水层系统的固有振动周期。分析了井孔变径对潮汐信号响应的周期特征，认为当含水层水体很大（含水层水平面积比井孔面积大得多），且含水层的渗透系数也很大的条件下，井径变化对井水位固体潮响应幅度影响很小

泌阳凹陷核桃园组微量元素演化特征及其古气候意义

泌阳凹陷下第三系核桃园组总体上表现为一个大的湖退体系，而其中的微量元素含量及有关元素比值却呈现出细微而明显的旋回变化特征。本文依据泥岩、页岩和碳酸盐岩中Ｔｉ、Ｓｒ、Ｂａ等十六种微量元素含量及Ｓｒ/Ｂａ、Ｆｅ/Ｍｎ、Ｓｒ/Ｃｕ等七种比值的变化特征，结合古盐度及岩相资料，对核桃园组沉积时的古气候作了系统的研究，基本上分出了温暖潮湿、干湿交替、炎热干旱、温热半干旱四类较为特征的古气候类型，以期为油气勘探提供依据。

Development of joints and shear fractures in the Kuqa depression and its implication to regional stress field switching

The superimposed basin must have undergone the changes of regional stress field. Study on the nature and switch of regional stress field of superimposed basin is very useful to understanding its stress state and tectonic events during its formation and evolution. As sensitive markers of small stress changes, joint and shear fracture, characterized by consistency of orientation over wide area, can be used to reconstruct paleostress state and its evolution. Detailed observations and analysis on the orientations, geometrical patterns, sequences of joints and shear fractures and their chronological relation to faults and folds show that, the NEE-SWW systematic joints and NNW-SSE systematic joints developed in the Mesozoic and Cenozoic strata are much more prominent than NW-SE systematic joints and shear fractures with different orientations. And the NWW-SEE and NW-SE systematic joints formed later than NEE-SWW systematic joints but earlier than shear fractures with different orientations. According to the relationships between joint and shear fractures and stress, the NEE-SWW systematic joints are inferred to result from lateral weak extension caused by the late Cretaceous regional uplift, while the NNW-SSE and NW-SE systematic joints are interpreted as syn-tectonic deformation relating to strong N-S compression in the Neogene. But some conjugate shear fractures occur probably due to sinistral strike-slip faulting in the Kuqa depression. At the beginning of the Neogene, the stress field changed and the maximal principal stress σ1 switched from vertical to horizontal.     

A Preliminary Analysis of Relations Between Tectonic Deformation of Sedimentary Cover and Basement in Kuqa Depression

Study of seismic activity in the Kuqa area enables us to infer some possible active faults in basement from the epicentral distribution on different profiles. The relations between active faults in the basement and surface structures are analyzed and the difference between sedimentary cover and basement in their deformation characteristics and the genesis are discussed. The following conclusions have been drawn : ( 1 ) the epicentral distribution indicates that, the east Qiulitag and south and north Qiulitag deep faults in the basement correspond to the east and west Qiulitag anticlines, respectively. Moreover, deep faults also exist beneath the Yiqiklik and Yaken anticlines. It indicates that the formation of surface structures is controlled by deep structures; (2) A NE-trending strike-slip fault develops along the line from the western termination of Yiqiklik structure to Dongqiu Well 5 and a NW-trending active fault on the western side of Baicbeng. The two active faults across the tectonic strike are the main causes for tectonic segmentation of the Kuqa depression and possibly the cause for the middle segment (Kuqa-Baicheng) of the depression to be more shortened than both its eastern and western terminations; (3) The difference between the sedimentary cover and basement in their deformation characteristics depends mainly on the different properties of media between them.The lithospheric strength of the basement in the basin is fairly high, which determines the basement deformation to be mainly of brittle fracture seismic activity. While the strength of sedimentary cover is low, where there exist weak thin layers, such as coal and gyps. Under the effect of strong tectonic compression, the sedimentary rocks may undergo strong viscous or plastic flow deformation; meanwhile, an aseismic detachment may take place along the weak layers.
