怀安盆地北缘断裂构造几何与活动特征

Geometrical Characteristics and Tectonic Activities of Northern Margin Fault of the Huai'an Basin

  • 摘要: 结合前人调查和研究资料,综合运用地形地貌分析、地质调查、遥感解译等方法,详细分析了怀安盆地北缘断裂的构造地貌特征,较为系统地研究了断裂带的几何结构、构造变形及活动特征。怀安盆地北缘断裂控制着怀安盆地附近的第四纪构造演化和地貌发育,根据断裂展布和活动性可分为3段,即东段(洗马林-东洋河)、中段(东洋河-马市口)和西段(马市口-韩家营)。怀安盆地北缘断裂为典型的山、盆构造界线,沿线断裂活动特征明显,断面上留有断层活动的痕迹——镜面构造、擦痕;不同段落具有不同的活动特征,东段活动性最强,中段次之,西段最弱。

     

    Abstract: Combining with previous investigation and research data, this paper analyzes the tectonic feature of the northern margin fault of the Huai 'an basin using the methods of topography analysis, geological survey, remote sensing, etc, systematically studies the geometric structure, tectonic deformation and fault activity characteristics of the active fault zone. Huai'an basin fault controls the development of the Quaternary tectonic evolution and landform near the Huai'an basin. According to the fault distribution and fault activity, it can be divided into three sections:the eastern segment (Ximalin-Dongyanghe river), middle segment (Dongyanghe river-Mashikou) and west segment (Mashikou-Hanjiaying). The fault is a atypical mountain-basin boundary, along which we can found significant activity characteristics in many places. There are fault activity traces on the fracture surface:mirror structure, scratches. Each stage has their own activity features, the east segment has the strongest activity, the middle segment take second place, the west segment has the weakest activity.
