Geomorphic origin,control basin factors and regional tectonic significance of Miyun Reservoir and adjacent areas
摘要
Abstract
To determine the lake-controlling structure and structural properties of Miyun reservoir basin by geomechanical method,three structural systems exist in the reservoir area,namely,the peripheral broom-like structure system,the Cathaysian system,the restricted broom-like structure system,and three kinds of pull-apart basin activities.Through geomorphic elevation zoning,it is shown that there is a NE-oriented quaternary low elevation corridor landform controlled by the NE-controlled"basin"fault,named"Huairou-Miyun subsidence belt".Miyun reservoir area and Yanluo Basin belong to the tectonogenic lake basins,and the limited broom-like structural system causes the differences between sub-basins in the Huairou-Miyun subsidence zone.Miyun reservoir area and Yanluo Basin are formed by a series of narrow channel depressions caused by three types of tectonic landforms:fault valley,micro-graben valley and mini-graben valley.It is a"hungry sedimentary basin"controlled by"tectono-genetic landform".The denudation resistance of miyun dome in the Huairou-Miyun subsidence zone causes a"shield effect",forms a"√"shape basin profile and controls the subsidence center of the reservoir area.关键词
