岩石的变形行为,除取决于岩石本身的特性外,还受变形时的温度、压力、变形速率等外界条件的影响.对于地壳断层带岩石的变形同样也是如此.在断层带的浅部,低温低压,岩石一般发生脆性破裂;断层带的中、深部,温度和压力增高,变形由脆性朝着韧性转换;在深部,达到一定的温度和压力,岩石的变形便过渡为韧性.按照上述认识,断层带岩石在
Deformation behavior of rock, except depending on the characteristics of the rock itself, but also by the deformation of the temperature, pressure, deformation rate and other external conditions for the deformation of crustal rock as well as the same in the shallow fault zone, low temperature Low pressure, rock brittle fracture; the fault zone in the middle and deep, the temperature and pressure increase, the deformation from brittle to toughness conversion; in the deep, to a certain temperature and pressure, the deformation of the rock will transition to toughness.According to the above understanding, Fault zone rock in
