摘　　要：连山关地区地处华北克拉通辽吉活动带,矿产资源丰富,但连山关地区的隐伏断裂及岩体的展布情况,仍然缺乏系统的研究.利用欧拉反褶积法,对重力和磁法数据进行处理分析,确定了潜在的隐伏断层的地下延伸,根据断裂的深部及分布范围,对其进行了分级;推断了侵入岩的空间展布特征.最终绘制了隐伏断裂和岩体分布图,研究结果突出了研究区的重要隐伏断裂和岩体,表明重力和磁法数据的深入研究,可以为发现隐伏断裂及岩体提供可靠线索.The Lianshanguan area,which located in the Liaoji active belt in the North China Craton,is rich in mineral resources.However,scholars still lack systematic research on the distribution of hidden faults and the distribution of rock mass in this area.Therefore,in this study,the Euler deconvolution method was used to process and analyze the high⁃precision gravity and aeromagnetic data of this area.We determine the underground extension of potential hidden faults and classify them according to the depth and distribution range of faults;we also infer the spatial distribution characteristics of intrusive rocks.Finally,we draw the spatial distribution map of concealed faults and rock mass.This study discusses the important concealed faults and rock masses in the Lianshanguan area,which shows that the in⁃depth study of gravity and aeromagnetic data can provide reliable clues for the discovery of concealed faults and rock masses.
