| 摘 要： | 黄陵背斜东北,西北及西南三边为大断裂所切割,唯其东南边缘仅在卫星影象上有一线性构造。经实地考察研究,该线性构造地表以张性裂隙带的形式出现,其深部部分地段以主断面形式出现,从而在几何形态上组成一个完整的黄陵菱形断块构造。在断块的顶角处,是该地区中强地震的主要发生地带。

| Abstract: | Althought three big faults obviously exist separately on the northeastern , northwestern and southwestern edges of Huangling anticline, the southeastern edge of the anticline merely shows a linear structure on satellite image. Field investigation and study indicate that the linear structure represents a consisting of a series of tensile cracks on the surface and shows a main fault plane in depth beneath its some sections .Geometrically these faults and the linear structure constitute a complete Huangling rhombic block. Moderate - strong earthquakes mainly occur in the tip areas of the block. |
