隐伏地质异常地表间接显示的物理模拟实验

PHYSICAL SIMULATED TEST OF INDIRECTED DISPLAY ON SURFACE CAUSED BY BURIED GEOLOGICAL ANOMALY

用物理模拟方法研究隐伏地质异常地表间接显示机理，探讨隐伏线性构造在水平挤压条件下的表面特征．在后期构造作用下，表面线性体破裂变形模式包含了隐伏地质异常的成因信息，可以通过地质力学分析方法提取和识别．

The authors research the mechanism of indirected display on surface caused by buried geological anomaly at first, on the basis of physical simulated tests. Discussed in this paper are the geological model, simulated condition, simulated process, test result and geomechanics analysis. After the research, the conclusions are drawn: (1) buried geological anomaly may be indirectly displayed on surface under condition of tectonic activization; (2) the model of lineaments on surface may include some information of buried geological anomaly, which can be abstracted from tectonic setting; and (3) based on further research, the origin mechanism of buried geological anomaly can be analyzed according to different features of lineament models.
