The Glycerol Dialkyl Glycerol Tetraethers(GDGTs) is a group of newly discovered microbial biomarkers.The proxies based on GDGTs have become important indicators for revealing the sources of sedimentary organic matters and reconstruction of paleotemperature.In this study,we analyzed the content of the total organic matters and the fluxes of GDGTs in the core sediments from the DH5-1 station(29°28.118′N、123°06.639′E,water depth 63.5 m) located at the shelf area.The changes of organic matter sources were reconstructed using δ13C,C/N and BIT indexes during the past about 150 years.The results indicated that the enhanced East Asian winter monsoon in the past century strengthened the transport of terrestrial material from the Yangtze River Estuary to the shelf area.However,since the 1980s,increased human activities caused more nutrients influx which elevated marine production and reduced the relative percentage of terrestrial organic matters in the sediments.

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.

Based on the latest re-processed and newly acquired seismic data and using the integrated approaches including seismic,well drilling,inverse gravity and magnetic processing and land sea correlation,we studied the distribution of the Mesozoic in the southern East China Sea Shelf Basin,and got some new understandings about the three uplifts,namely the Yandang,Taibei and Guanyin uplifts,defined by previous studies.It is found that the Yandang Uplift is in fact not a continuously uplift from north to south,but an old Proterozoic uplift made up of three en echelon uplifts,which disappear southward.Mesozoic strata occur steadily on both the Guanyin and Taibei uplifts.Our results show that the Mesozoic strata in the Southern East China Sea Shelf Basin are quite thick and widely distributed.According to our data,it is thicker in the south and east,and thinner in the north and west.In this regard,the concept of Mesozoic Great East China Sea is proposed in this paper to conclude the new discoveries.

An integrated provenance analysis has been performed for the sanbodies of the Hetaoyuan Formation in the Wuyang Depression based on cathodoluminescence slice and the shape and chronology of zircon debris in the sandstone.The result indicated that the source of the sandbodies in the Second Member of Hetaoyuan Formation disclosed by well Wu3 and Wu8 came from the southern uplift of the depression.It is an opinion different from previous studies.Then a new sandbody distribution map and a depositional model were put forward by the authors in this paper.It is seen from the map that the spatial distribution pattern of sandbodies is remarkable different in the south from the north.The braided river delta stretched far into the depositional center on the southern slope,whereas the fan deltas on the northern steep slope only occur along the boundary fault in small patches.

Two-dimensional seismic and gravity-magnetic data were processed and interpreted by the authors in order to study the temporal and spatial distribution of igneous rocks in the East China Sea Shelf Basin and its adjacent regions.Data from the land,mainly from Zhejiang and Fujian provinces were collected for the purpose of correlation.Igneous rocks are widely distributed in Zhejiang and Fujian.They occur in a NE trending to the north and NNE trending to the south of 28 N.They are shallowly buried and controlled mainly by major faults.The igneous rocks offshore are mainly distributed upon uplifts or along the fault boundaries of depressions.Temporally,the igneous rocks in the study area can be subdivided into four stages,i.e the Yanshan stage,Sichuan stage,Huabei stage and Himalayan stage and spatially occur in four zones,say the Zhe-Min uplifted zone,Central uplifted zone,Diaoyu Island folded uplifting zone and Ryukyu arc zone.

The evolution of the Qingshuigou lobes of the Yellow River in the past 30years is studied in details in this paper.Composite false color remote sensing images since 1976 were used for detecting the changes in shoreline and river channels.Bathymetric data from 1976 to 2005 were processed for study of the depositional and erosional pattern of the subaqueous delta of Qingshuigou lobe.The evolution of the subaqueous delta was divided into 4 phases,multi-center depositional phase,single stable depositional phase,slow depositional phase and depositional erosional phase as the response to the evolution of Qingshuigou channel.Moreover,the factors influencing the evolution of the deltaic lobe were investigated.
