摘　　要：皖北地区位于华北陆块南缘,第四系广为覆盖,地质研究程度因此受到相应的制约。本文结合地质和物性等资料,在对1:20万重磁资料处理分析的基础上,对皖北地区主要断裂格驾进行了解译,认为皖北地区主要发育北北东、北西西、近东西等走向的断裂,另在徐州至宿州发育弧形断裂;其中北西西走向断裂发育时间相对较早,近东西次之,而北北东走向断裂发育时间相对最晚,晚期发育的断裂错断了早期发育的断裂。The northern Anhui area is located on the southern margin o f the North China landmass,with widespread Quaternary overburden,which thus constrains the degree of geological research.Based on geological and physical property data,processing and analysis of 1:200000 gravity and magnetic data,this paper has interpreted main fracture frameworks in the area,and argued that NNE,NWW and nearly EW faults dominate in the area,and an arc fault is developed from Xuzhou to Suzhou,of which NWW faults developed earlier,the nearly EW followed,and NNE formed relatively latest,and the late faults offset the early ones.
