引言我们知道:欠压实异常与压力异常条件有关,并可以利用地震速度检测这类异常。这里所述史例则是关于另一种异常带的,这种异常带在欠压实地层下才能遇到。据信,这种异常带是由高流体压力下形成的开放性断裂系统引起的。在简述了某些地球化学概念和
Introduction We know that undercompact abnormalities are related to abnormal pressure conditions and can detect such anomalies using seismic velocities. The historical example described here is about another anomalous belt, which can be encountered under uncompacted ground. It is believed that this anomalous zone is caused by an open fracture system formed under high fluid pressure. Some of the concepts and concepts of geochemistry are outlined
