Abstract:

There are multiple sets of hydrocarbon source rocks developed in South China,which experienced several tectonic events.By analyzing deformation succession,four deformation phases are recognized for Paleozoic marine hydrocarbon source rocks in South China,on a basis of field observation and seismic section interpretation,i.e.,late Early Paleozoic(421-441 Ma),Late Triassic(215-230 Ma),Late Jurassic-Early Cretaceous and Early Cretaceous-Tertiary.It is suggested that the main deformation phases occur in the Middle-Late Mesozoic,forming superimposed structures with different sizes.

Key words: superposed structure, main deformation phase, marine hydrocarbon source rock, Mesozoic, South China
