| Abstract: | The formation and evolution of marine sedimentary basin has a good relation with the divergence，convergent and ambient mountains formation of Yangtze plate.Main source rock formed in margin of passive continental and depression inter platform of foreland basin in the period of early Paleozoic and rift basin inter craton in the period of later Paleozoic.Whether the source rocks are effectiveness or not depend on their evolution in later tectonic reformation and the content of preservation at last.There are two petroleum combinations in marine sequence southern China.The marine sediment exists as residual basin after multi tectonic superimposed and reformation.A large part area experienced obviously erosion，since Indosinian movement up to now.The content of basin reformation controls the scale of hydrocarbon accumulation and preservation.The key exploration area should be located in good preservation basin with gentle reformation，good sealing，and regional cap rock distribution.In the procession of hydrocarbon exploration of marine sequence in southern China，the effectiveness of superimposed prototype basin，source rocks，preservation and hydrocarbon combinations should be analyzed dynamically.Especially，the marine sequence distribution area has experienced multi tectonic superimposition and reformation，the studies and evaluations of whole preservation in these areas should be devoted more attention，which is main factor controlling present hydrocarbon accumulations. |
