安徽南部东西向断裂构造的遥感研究
|
摘要
安徽南部是我国长江水患频发区之一 ,该区地质构造对水患成生起着重要的控制作用。在经过增强处理的遥感图像上 ,通过分析断裂构造的几何、运动、动力、性质特征等判别标志 ,运用TM卫星遥感数据及“证据会聚”的调查研究技术 ,对该区的东西向线性构造进行了解译 ;结合地震、温泉等资料 ,认为区内近东西向断裂分布广、多期活动特征明显并对新生代盆地及铜矿床有重要控制作用 ;特别指出了东西向断裂是影响长江断裂带发育及长江形成鹅头型河流的重要原因。研究成果将对研究区大型工程的配置、地震预报及新构造运动的研究有重要借鉴意义
The central and southern area of Anhui province, a district adjacent to the Changjiang River, is suffered frequently from the flood whose emergence is controlled by the geologic tectonics. After analysing the linear tectonics's characteristics of the geometry, movement, dynamics and property at enhanced remote sensing pictures. the evidence-cluster investigation is used to interpret the east-west linear tectonics of the above region .Then combine to the information about the earthquake, warm wells etc. It is concluded that these fractures are distributed widely, close correlative to the regional tectonics and especially that it is these east-west fractures that influenced the development of the fractural belt of the Changjiang River and the formation of the goose-head-like rivers. The study will offer help to large engineering project and study of neotectonics .
