摘要: 同生断层活动速率反映了该断层的活动强度。它不仅与单位时间内断层上、下盘各地层单元的厚度盖有关,而且还与地层的差异沉积速率有关。本文介绍了受盆地沉降因素控制的沉积速率在横向上发生变化时,如何根据地层厚度、同一层两个断点的古水平位移、差异沉积速率求取断层活动速率的方法,推导出了断层活动速率的一般关系式,并通过实例的计算对新老方法进行了对比。

Abstract: Moving velocity of a contemporaneous fault reflects its moving intensity. It is associated not only with thickness difference of the formations in upper and lower walls of the fault within one time unit,but also with the differential
