Being bounded by the Silurian regional detachment

the marine stratigraphic series in southern China can be divided into lower and upper two structural layers. According to the strength and characteristics of deformation of the structural layers

as well as their combination features

the geologic configuration of marine stratigrahpic series in southern China can be classified into 7 types

i. e. single layer stable

double layer continuous

double layer fault-folded

single layer imbricated

double layer thrust-slipped

single layer thrust faulted and binary nappe types. Multiphase subsidence and upheaval since Indosinian have led to the formation of 6 kinds of burial evolution history

which can be grouped into two large types

namely"early subsidence-late upheaval"and"early upheaval-late subsidence". The initial buildup of marine sedimentary formations

later reconstruction by tectonic movements and the superimposition of the overlying non-marine formations have resulted in 4 play types

including primary type

reconstructed type

regenerated type

and epigenotype; of which the primary play type has good oil and gas preservation conditions

and thus has good exploration prospects. The plays of regenerated type and epigenotype in the Middle and Lower Yangtze areas have certain exploration prospects

too.
