Abstract: The hydrocarbon geochemical exploration anomalies of raised submarine reefs are the result of reservoir matter in the deep Precenozoic sedimentary basin leaching upwords.In the East China Sea Shelf Basin on the north of the Jiumi-Yushan Major Fault,we should not only continue to look for the Cenozoic oil and gas pools,but also find the oil and gas pools in shallow strata whose hydrocarbon is from deep sources and is formed in the Paleozoic and accumulated in the Cenozoic.This is the new domain of oil and gas exploration in the East China Sea.The major gas source rocks of large oil and gas pools/fields in the East China Sea may be the Paleozoic strata.
