DISTRIBUTION OF TRIASSIC STRATA IN THE SOUTHERN EAST CHINA SEA

Based on the data on the distribution pattern of Upper-Triassic strata in the land area close to the East China Sea and the Ryukyu Island Arc, in combination with the latest high-resolution seismic data from the East China Sea area, It is inferred that Triassic strata may exist in the southern East China Sea, and contact with the overlying strata conformable or disconformable in the south and unconformable in the north. The Upper-Triassic deposits were formed in a deepwater environment, and there is big potential for oil and/or gas generation. In this regard, the Triassic strata in the southern East China Sea could be a new important target for oil-gas exploration.
