| 摘 要： | 冷底辟是指盐、膏、泥岩等塑性地层向上侵入或刺穿所产生的构造样式;热底辟主要指岩浆侵入或喷发所产生的底辟构造样式。不论哪种底辟构造,在人工地震剖面上反映均非常明显,其底辟内部呈杂乱反射,而围岩反射界面在此突然中断。在岩浆底辟处常出现磁力高异常,并有较高的层速度,冷底辟具有较低的层速度,盐膏底辟也具有较高的层速度。构造与火山地震关系密切,而冷底辟也可以形成破坏性地震,是今后值得注意的研究课题

| Abstract: | Under the effect of external force,plastic layers in subsurface and deep crust would result in diapirism,and the resulting structure is called diapiric structure,which can be divided into two types according to their nature,one is cold diapir and other is hot diapir.Cold diapir is defined here as the structural style resulting from diapirism or upward movement of plastic material such as salt,gypsum and shale.Hot diapir is defined as the diapiric structural style resulting from magmatic intrusion or explosi |
