| 摘 要： | 在对天水地区新构造运动进行实地调查的基础上,首先对各种新构造运动的表象进行了较为详细的研究;其次,根据新构造运动表象,分析研究了各区的新构造运动特征,结果表明:天水地区新构造运动具有差异性升降运动明显、差异性升降运动速率不均匀、新构造运动强度空间上不均匀、断裂活动性强、地震活动频繁等特征;最后简单分析了天水地区新构造运动演化过程,认为天水地区经历过3次大的夷平过程。

| Abstract: | On the basis of the investigations to the neotectonic movement of Tianshui area,Manifestations of various neotectonic movements are studied in detail firstly.Secondly,according to the manifestations of various neotectonic movements,the neotectonic movement features of each zone are studied.The result shows that the neotectonic movement of Tianshui area has such features:the relative vertical motion is obvious,the rate of relative vertical motion is unequal,the neotectonic movement intensity is unequal on the space,the fault activity is strong,and the earthquake is frequent.At last,the neotectonic movement to evolution process is analyzed in brief.The level process is considered on Tianshui area. |
