Abstract: Sedimentary facies indicators are the best effective criteria to identify seismites. In the flume experiments to simulate seismoturbidites, several typical facies indicators of seismites are found in soft sediments, such as synsedimentary faulting, microcorrugation, liquefied sandstone dike, liquefied uniform bed, syndepositional deformation, seismoturbidites, and so on. They formed in different periods of seismism and distribute regularly in the system of delta to seismoturbidites. At the same time, some facies indicators induced by other contributing factors are discovered, which is confused with facies indicators of seismites. So when analyzing seismites we should also consider the assemble characteristics of all kinds of facies indicators, their allocation relationship with depositional environment and regional tectonic setting. The distribution pattern of facies indicators of seismites can be derived from simulated experiments. According to analyzing the types and assemble characteristics of facies indicators of seismites, we can forecast the best zones that develop seismoturbidites and guide subtle reservoir exploration in faulted basin.
