Exploration for marine hydrocarbon has gained great attention in China recently.The Pre-Cenozoic marine strata were widely distributed in the South Yellow Sea.In order to better understand these strata,we made comparison in this article of the marine strata and their depositional features between the South Yellow sea and the Sichuan basin in the upper Yangtze with the well data from the South Yellow sea and the lithostratigraphic data from the Upper Yangtze area.It is concluded that the Mesozoic and Paleozoic marine strata in the two areas dominated by carbonate platform deposits are generally similar before Indosinian movement,but different in the time and scale due to the tectonic movements in Paleozoic and Mesozoic.The sediments are comparable between the upper and lower Yangtze.Also discussed briefly are the source rocks and reservoir storage capabilities between the two regions.The successful exploration for marine oil and gas in the Sichuan Basin has provided a benchmark for the assessment of oil and gas potential and exploration of marine hydrocarbons in the South Yellow Sea.

Several types of positive inversion structures are developed in the Cenozoic strata of the Northeast Sag,North Sag,Middle Sag and South Sag in the North Depression of the South Yellow Sea Basin,including penetrated fault-propagation type,compressive fold type,reversed fault type,and so on.Oligocene and the end of Pliocene are the two main inversion periods,and the structural inversion in Oligocene is more obvious.The convergence rate between the Pacific Plate and Eurasia Plate is an important factor controlling the development of inversion structures in Cenozoic in the North Depression of the South Yellow Sea Basin.The positive inversion structures are favorable to hydrocarbon accumulation and unfavorable to hydrocarbon preservation if the intensity of tectonic inversion is great.

Sediment grain size,organic carbon content(TOC),carbonate content and stable carbon and oxygen isotopes of carbonates in the Dishaogouwan section on the south edge of the Mu Us desert in Inner Mongolia were sludied in this paper.Age data were used to establish an age model for this section.All the sedimentary and geochemical paleoenvironmental proxies were used to reconstruct the palaeoenvironmental changes since 11 000 aBP,to 4 380 aBP,early to mid Holocene in this area.During the period from 11 000 aBP to 9 950 aBP,the study area was cool and dry.Precipitation in the south north part of Shanxi Loess Plateau and the water from melted Dishaogouwan frozen stratum were the main replenishment water for the Salawusu cathment.During the period of 9 950~9 100 aBP of early Holocene,temperature and precipitation increased with a high effective humidity,and the Dishaogouwan lake came into being.From 9 100 aBP to 5 850 aBP,temperature and precipitation continued to increase but effective humidity was a little lower,while the lake developed to its maximum and lasted for a long time.From 5 850 aBP to 5 100 aBP,temperature and precipitation started decreasing and the lake shrank at the same time.From 5 100 aBP to 4 700 aBP,palaeodune formed in this area under dry climate.There was a short period of temperature and rainfall rising during 4 500~4 380 aBP,and a small lake formed over a carbonate impermeable layer.Desertification has prevailed under the dry condition since 4 380 aBP up to present.

A lacustrine sediment core(DY6) was collected from the "Nietang Pond" on Dongdao Island,South China Sea(SCS).Geochemical,morphological,and mineralogical analyses were performed for the sediment samples.The results of major elements showed that the concentrations of Ti and Al in the sediment samples were much higher than those in three end-members(coral sand,guano and plants).Hierarchical clustering analysis of geochemical elements indicated that Al and Ti were exogenetic.Furthermore,according to the microscopic analysis,there are more acid-insoluble particles in the subsamples with high Ti(Al) contents,some of which showed similar morphological characters with the eolian dusts from Hefei,the loess-paleosol particles from Korea and the dust deposits from the north of SCS.The major elements concentrations of the acid-insoluble particles surfaces detected by X-ray energy spectrum revealed that these particles were mainly made up of silicate and quartz.Consequently,the accumulation of Ti and Al in the lacustrine sediments of Dongdao Island was quite possibly caused by the input of the terrigenous dust from the interior of Asia continent.The East Asian Winter Monsoon might be the transportation medium.

The HMD Core(29°59.064′N、121°21.754′E) was collected near the Hemudu Civilization site at Ningshao Plain,the southern bank of Hangzhou Bay.The core is 45.3 m long with clay and silt as its main lithological components.The results of grain size,C/N ratio,organic carbon isotope(δ13CTOC) value and pollen analysis reveal the sedimentary environmental changes and paleoclimatic evolution stages in Ningshao Plain since LGM.It also shows that,the main organic source of HMD Core was from endogenous water plants,and the δ13CTOC values variation was mainly controlled by the change in atmospheric CO2 pressure.It is a good response to global climatic changes.

The evolution and extinction of the Tethys was a major global geological event in Cenogoic and is one of the decisive influences on the formation and evolution of the arid environment in Eurasia,especially Asia.This paper briefly made a review of the progress of the international Tethys programs,combined with our researches.The evolution of the Tethys can be simply divided into three stages,the Tethys,Paratethys and Tethys extinction.In Late Mesozoic to early Cenozoic,most parts of Europe,Western and Central Asia region and the Southern Tibetan Plateau joined together and formed an inland sea named the Tethys which connected with the Atlantic Ocean to the west and with the Ceno-Tethys to the east.About 34 Ma ago,The Tethys connected with the Atlantic,Indian and Arctic oceans and the most eastern part of it extended into the Tarim area.With the collision of Indian and Eurasian plates,the Tethys retreated from the Southern Tibetan Plateau and the Tarim area.Then the Tethys was separated into the Mediterranean in the south and Paratethys in the north about 34 Ma ago.Under the joint effect of global sea level change,tectonic uplift,surface erosion and sediment filling,the Parathtys experienced a series of eustatic,and area changes and closing and opening of seawater channels,The greatest impact on the environment came from the channel closing-opening of the Paratethys,the ancient Mediterranean and the Indian Ocean.Since Oligocene there occurred at least four times of close-open cycles.The evolution and extinction of the Tethys especially since the withdraw of Tethys from the Tarim region 34 Ma,the rapid shrinkage of Tethys about 20 Ma and the closing of water channels with other oceans around 7-8 Ma may be the main factors leading to the drying up in Asian inland area.

The paleo-vegetation changes of the Ulan Buh Desert since last Glacial are discussed according to the lithology,chronology and pollen analyses of the drill core WL10ZK-1.The high content of Typha pollen(up to 12%),and a quantity of Picea(up to 22.5%),Poaceae and Cyperaceae pollen from the bottom of drill core indicate that there was a lacustrine environment with steppe vegetation in the Ulan Buh Desert before 90 ka.Since 90 ka,xerophytic/halophyte herbs or shrubs such as Chenopodiaceae,Artemisia coupled with Tamaricaceae and Zygophyllaceae dominated the pollen from the middle of the drill core which indicates a desert vegetation environment occurred during the last glacial.During the phase of 8~7 ka,the UBD is dune-pond environment with steppe vegetation characterized by high percentage of Pinus and Artemisia.

The coastal beach,as a precious natural heritage,is the most beautiful natural landscape and the engine for tourism development along the coast.It has raised great attention both at home and abroad.The working group of Ocean University of China has established the Shandong coastal beach information archives after three years of systematic investigation and research.There are 123 coastal beaches in Shandong,with a total length of 365 kilometers of coastline.They,in terms of spatial distribution,look like a bunch of beautiful pearls inlaid around the Shandong peninsula.This study,however,has found that 98 of the coastal beaches have been under erosion,accounting for about 80% of the total number of beaches,caused by human activities.In view of the important value of coastal beaches in social civilization and development,we suggested that Shandong province and all levels of governments under it should raise the awareness of coastal beach protection and focus more on the countermeasures against coastal erosion,with rationale planning as the first priority.
