根据航磁、重力和地震数据以及地质和辅助地球物理资料,对约旦东北部前寒武纪岩石的轮廓和变化及其上覆的沉积岩石的厚度进行了研究.识别出5个具有特定磁性特征的磁场区,每个磁场区都有其特征的样式和突变的边界,每个磁场区的物质组成存在明显差异,其构造边界均与断层相对应.计算表明基底表面有很大起伏,磁化的前寒武纪岩石深度变化范围为-5000m至-10000m,可以识别出由基底下陷相对应的5个盆地或拗陷带,同时可见3个起伏较大的构造隆起.探测结果表明,古生代建造中发育的主要断裂呈N-S与NNE向,而在新生代建造中发育的断裂则呈NE-SW,NW-SE和E-W向.研究区构造发展的第一构造阶段与E-W向张力有关,第二构造阶段的产物明显受到第三构造阶段发生的构造变形的改造,并与阿拉伯板块的逆时针旋转有关.磁场区之间的移位、错断、拖曳和并置被认为剪切断层所造成.剪切形式表明位移是左行的,即北侧的块体向北西方向移动.
Based on aeromagnetic, gravity and seismic data, and geological and ancillary geophysical data, the profile and variation of Precambrian rocks in northeastern Jordan and the thickness of overlying sedimentary rocks were studied. Five magnetic field regions with specific magnetic characteristics are identified. Each magnetic field region has its own pattern of features and abrupt boundaries. The material composition of each magnetic field region is obviously different and its structural boundary corresponds to the fault. Computation shows that there is a great fluctuation in the surface of the basement, and the pre-Cambrian rock depth varies from -5000m to -10000m. Five basins or depressions corresponding to subsidence of the basement can be identified, and three ups and downs Tectonic uplift. The results show that the main faults developed during the Paleozoic were N-S and NNE, while the faults developed in the Cenozoic were NE-SW, NW-SE and E-W directions. The first tectonic stage of tectonic development in the study area is related to the tension of E-W. The product of the second tectonic stage is obviously modified by tectonic deformation in the third tectonic stage and is related to the anticlockwise rotation of the Arabian plate. Displacement, misjudgment, drag and juxtaposition between magnetic field regions are thought to be caused by shear faults. The shear form shows that the displacement is to the left, that is, the north block moves northwest.
