Deep-water facies of the Pliocene sediments in southwesternCaspian Sea

Abstract:
      Twelve seismic profiles northwest of Rudsar and Anzali (Iran), were investigated to define seismic facies and potential stratigraphic traps in the Pliocene sediments of southwestern Caspian Sea. The deep-water facies occur as sediment mounds, prograding clinoforms, buried channels and debris-flow lobes. Potential stratigraphic traps may be found in the first three forms; among which sediment mounds are more significant. The largest mound is 18.8 km wide and 480 m high. Various internal reflection pattern of these mounds indiacate different processes (i.e. passive settling, turbidity current and debris flow) were active during their formation.
