The Paleozoic burial types of the east uplift in Liaohe Basin could be divided into three kinds

i.e.relative subsidence type

later subsidence type and secular uplift type.Combined with the data of its geothermal evolution

the hydrocarbon property of this area was analysed.In the relative subsidence area

part of the Paleozoic group may re generate hydrocarbon and the Lishugou Formation of Lower Cretaceous may have hydrocarbon generating patential.The other two types have hardly any hydrocarbon due to their shallow burial depth.From the view point of structural evoluion

primary and secondary pools may be found in the conjunction parts of the Paleozozic uplifts and the Mesozoic depressions.If there are good source sags to match laterally monocline pools

secondary Cenozoic pools with Paleozoic source rocks may be found.
