摘要
Three problems are discussed in this paper: 1) superimposed types of extensional fault depressions at different epochs; 2) formation mechanism of these interference types is controlled by following factors. The synthetic and convergent interference types are related with arrangement of synthetic and convergent preexistent basement faults and longitudinal or transverse migration of fault activity, whereas the intersecting interference type is related with rotation of extensional direction with time; and 3) Hydrocarbon occurrence is related with various superimposed types of the fault depressions.
