摘　　要：将磁性界面与密度界面分布特征相结合进行分析,可以了解盆地的分布以及定量或半定量地了解沉积厚度。根据相关资料,结合重磁系列图件和解释图件,对东秦岭-大别造山带两侧盆地(洛阳-伊川地区、周口坳陷、合肥坳陷、南襄盆地和江汉盆地)进行了分析,其中重力和磁场的界面深度仅供参考。The magnetic interface distribution characteristics were combined with that of density interface for analysis,it could be used to clarify the basin distribution,quantitatively and semi-quantitatively understand sediment thickness.Based on related data and in combination with heavy magnetic series diagram and interpreting diagram,the basins including Luoyang-Yichuan Area,Zhoukou Depression,Hefei Depression,Nanxiang and Jianghan Basins on both sides of East Qinling-Dabieshan Structural Belt are analyzed,of which the interfacial depth of gravity and magnetic field is for reference only.
