锡斯特龙地区的沉积岩墙沿上阿普第阶和下阿尔布阶地层中的先存破裂发育.砂岩墙的分叉和分枝现象显示了这些破裂的动力学特征.两组共轭直立岩墙初始方位的三维统计分析,揭示了它们的形成机制以及该区岩床-岩墙体系发育期间的主应力方位。产在该区的另一组砂岩墙表明,在经受挤压构造作用之前本区曾发生过同沉积的构造活动和伸展断裂作用。几种显著的砂岩墙形态很清楚地显示出砂粒充填的破裂的剪切方向,并使该区砂岩墙形成时的应力型式得以辨认。
Sedimentary dikes in the Systron area were developed along the pre-existing ruptures in the Upper Appugard and Lower Albuchian strata, and the bifurcation and branching of the sandstone wall showed the kinetic characteristics of these fractures.The two groups of conjugate erect The three-dimensional statistical analysis of the initial orientation of the dyke indicates the formation mechanism of the dyke and its main stress orientation during the development of the sank-dyke wall system in this area. Another group of sandstone walls produced in this area indicates that syn-sedimentary tectonic activities and extensional faults occurred in this area before being subjected to compression tectonics. Several prominent sandstone wall patterns clearly show the direction of shear fracture of the grit pack and identify the type of stress at which the sand wall was formed.
