走滑断层尖端破裂带马尾状断裂的性质、发育过程和形成演化控制因素的物理模拟研究
Physical Simulation Study on the Nature,Development Process and Formation-Evolution Controlling Factors of Horsetail Fault in Strike-Slip Fault Tip Damage Zone
摘要
Abstract
Horsetail faults are typical structures within the tip damage zones of strike-slip faults and serve as important criteria for identifying strike-slip faults on planar maps.They are widely developed in various geological environments,especially in small-scale strike-slip fault systems within cratonic interiors.Currently,there is still controversy regarding the nature of horsetail faults,with an unclear understanding of their specific development process and the controlling factors of their formation and evolution.The lack of physical simulation experimental results as supporting evidence hinders fault identification,correlation analysis,sequence analysis and the study of tectonic background restoration in certain research areas.Using quartz sand as the material,a physical simulation study was conducted on the horsetail fault to clarify its properties,reconstruct its development process,and analyze the controlling factors for its formation and evolution.Horsetail faults can exhibit both extensional and compressional characteristics and their development occurs as strike-slip faults progress from wall damage zones to tip damage zones.Main controlling factors include fault displacement,lateral stress,caprock thickness and non-penetrating degree.关键词
