摘　　要：基于阳关寨勘查区野外地质填图、测井及钻孔等资料,结合构造地质研究方法,系统分析了阳关寨勘查区的构造特征。结果表明:阳关寨背斜勘查区早期受近EW向挤压形成近SN向构造,中期受NE向挤压形成NW向构造,后期受EW向挤压和伸展改造早期构造。构造成因是燕山早期受水城同沉积断裂影响,区内构造以北西向为主,构造应力为先期反旋挤压、后期顺旋挤压和拉张,后期构造对早期构造叠加改造所致,NW向构造对煤炭赋存影响较大。Based on geological mapping, logging and borehole data and combined with structural geology research methods,the geological structures and coal-gathering regulations were systematically studied. The results shows that： the Yangguanzhai exploration area is controlled by the NE trending anticline in early to mid NW extrusion forming structure,controlled by EW trending extrusion forming near SN trending fault,the latter by NEE to form NWW tectonic extension.Tectonic origin is Yanshan city early synsedimentary faults,structures in the area in the North West trending,tectonic stress as early anti spin clockwise extrusion,extrusion and extension period,tectonic structural superimposed on the early due to influences of structures on NW,the occurrence of coal is larger.
