论区域航磁异常轴向与各类构造形迹及其能源分布的关系——地质解释之二

ON THE RELATIONS OF TRENDS OF AXES OF REGIONAL AEROMAGNETIC ANOMALIES TO VARIOUS STRUCTURAL FEATURES AND DISTRIBUTION OF ENERGY RESOURCES

摘要: 地球是在不停的运动着。岩石层在它的历史发展过程中,总是在不断地变化,并旦永不停止。因此,在地壳的岩石中就保留了各次运动的构造形变和痕迹。由于结晶基底具有磁性,航空磁测能反映出基底构造的形态,划出异常的轴向分布图,就可以直观地显示烙印在磁性基底岩层中各类构造的形态。在利用航磁异常轴向的分布规律和特征来分析地质构造形迹时,我们采用了“轴向构造”一词,即表示描述的构造形迹是以航磁异常轴向分布特征为依据的,它有时是磁性岩

Abstract: The trends of axes of aeromagnetic anomalies in eastern China（east of Longitude 102°E）are shown in the map.They are used to describe the structural features,termed axial structures,which include three types:1. huge linear type:E-W,S-N,NNE NE,and NW（NNW）trends;2.curve type:a.arcuate structural system,b.wave structual system and c.epsilon -type structural system;3.cross type:a.lampda-type structural system, b.radial structural system,c.Y-type structual system,d.brush-type structural system,e.π-type structual system and f.grid-type structural system.Among them some are known,while other are unknown yet. This paper pays special attention to the relations between the structural features and the distribution of oil,coal and hot springs in eastern China.
