摘要:
基于数字高程模型(DEM)数据解译,结合野外地质调查、遥感影像及前人研究成果,对茶陵—永兴盆地构造地貌特征及断裂的制约关系做出初步研究,并探讨了少震、弱震区域盆地的演化历史。研究表明:茶陵—永兴盆地边界坡度和地貌差异显著,高坡度区域分别位于盆地的南东侧和北西侧,坡度陡立区域呈线性分布,与区内断裂空间展布一致,显示出断裂对茶陵—永兴盆地构造地貌的发育有较强制约作用。另外,盆地内部及周边不同时代沉积层厚度的分布情况及规模与数字地形剖面分析结果存在较好一致性,反映了构造地貌特征与多期次地质构造运动的相关性,以及盆地演化和地貌生长模式的阶段性特点。
Abstract:
Based on data interpretation of digital elevation model(DEM), combined with field geological survey, remote sensing images and previous researches,tectonic geomorphological characteristics and the restrictive relationship between faults of Chaling-Yongxing basin are preliminarily studied, and the evolution history of regional basins with few earthquakes and weak earthquakes are discussed. Research shows that the boundary slope and geomorphology of Chaling-Yongxing basin are significantly different. The high slope areas are located respectively on the south-east and north-west sides of the basin. The steep slope areas are linearly distributed,which is consistent with the spatial distribution of faults inside the area, displaying the strong restrictive effect of faults on the development of tectonic landforms of Chaling-Yongxing basin. In addition, the distribution and scale of sediment thickness in different periods within and around the basin consistent well with the results of digital topographic profile analysis, reflecting the correlation between tectonic geomorphological characteristics and multi-stage geological tectonic movements,as well as the stage characteristics of basin evolution and geomorphological growth model.
