Based on the paleomagnetic data from Tibet and adjacent areas,and the studies on paleogeography,petrlogy,sedimentology and tectonic deformation,we quantitatively reconstructed the relative position and relative motion of the blocks in Tibet area.The Qiangtang block began to drift northwards rapidly in Late Carboniferous,and collided with the ancient Asian continent during Late Permian to Early Triassic.The Gangdise block separated from the Gondwana continent in late Triassic,and collided with the Qiangtang block during Early-Late Cretaceous.The Himalayan block separated from the Gondwana continent in Late Jurassic,and began to drift northwards rapidly in Late Cretaceous,and collided with the Gangdise block during Late Cretaceous to Early Tertiary.

There are many small and medium-sized Cenozoic sedimentary basins in the southern South China Sea,such as the Nanweixi Basin,the Beikang Basin,the Liyue Basin,the Zengmu Basin,the Nansha Trough,the Brunei-Sabah Basin,the Northwest Palawan Basin and other basins from north to south.In general,NE-trending faults control the formation of the half grabens with faulting in the north and overlapping in the south.However,single grabens are mainly developed in the northern continental slope,while two-layered basins developed in the south of the region,of which the lower layer is the graben and the upper layer the imbricated nappes.According to the nature of main controlling faults and the transition of the basins at different evolutionary stages,these basins can be divided into three groups: the rift basin group(the Nanweixi,Beikang and Liyue basins),the rift-pull-apart-foreland superimposed basin group(the Zengmu basin) and the rift-foreland basin group(the Nansha Trough,Brunei-Sabah,the Northwest Palawan basins).The formation of these basin groups is closely related to major marginal faults of the basins and secondary faults in the sub-basins.Based on the nature of the faults,the basin-controlling fault belts can be subdivided into three types: tensile,shear and compressional,including the extensional fault belt in the northern edge of the Nansha Trough,the strike-slip fault belts at the west edge of the Wanan Basin and the Lupar and the Tingjia-Lee Jun Fault belts,and the thrust fault belt in the southern edge of the Nansha Trough.Tectonic events which happened in southern South China Sea,such as the South China Sea Movement in Oligocene and the Nansha Movement in the Middle Miocene,affected the basins to various degrees.As the result,there was the inversion from a rift basin/pull-apart basin to a marine foreland basin,as well as the inversion of fault belts from normal faults to reverse faults or strike-slip faults.The kinetic mechanism of the basin groups varies in different stages.In the early stage,it may be related to the continental rifting of the southeast edge of the Eurasia continent,and the subduction and dragging of the Paleo-South China Sea slab resulted in the splitting of southern South China Sea from the South China continent,and then,half garbens formed with faulting in the north and overlapping in the south.In the later period(about 16 Ma),the north-directed imbricated thrust nappes propagated forward in the southern South China Sea due to the collision of the southern Australian Plate to the northern Eurasian Plate,which resulted in the transition of basin types and the counterclockwise rotation of the Borneo Block.

Two sediment cores were recovered from the Bosten Lake in order to investigate the changes in both the lake system and source of organic materials during the last 200 years.Based on 210Pb/137Cs chronology,stable isotopes of organic carbon and nitrogen as well as Loss on Ignition(LOI),grain size and magnetic susceptibility(MS) were analyzed.The results indicate that the agricultural activities in the catchment of the Bosten Lake have much earlier influence in the lake center rather than in the river mouth.Due to the general increase in regional humidity during 1810—1883 AD,δ13Corg declined rapidly in the core BST16,while abrupt increases in δ15N were found as more terrestrial material could reach the lake center.After the establishment of Xinjiang Province in 1884 AD,intensified agricultural activities have led to marked decrease in the medium grain size,and relatively higher δ13Corg and lower δ15N in the core BST16.Since 1950 AD,large scale agricultural activities have led to the rapid decrease in δ13Corg and increase in δ15N,indicating a general increase in the trophic level.Further decrease in δ15N together with the increasing δ13Corg after the 1990's indicates that nitrogen fixation by algae began to dominate the lake primary productivities.

The South China Sea is located at a juncture among the Eurasian,the Indian-Australian and the Pacific plates,being the largest continental marginal sea along the East Asian continental margin.It has experienced a complex transition of continental marginal types.The northern margin was an Andean-type continental margin before 80 Ma,then gradually transferred into a rifted continental margin in the Eocene and a typical passive continental margin since the middle Miocene.The eastern margin was an open water before 17 Ma and gradually became a subduction zone of the trench-arc-basin system by one-way subduction to double-way subduction,when the South China Sea became semi-closed basin since 6 Ma.The western boundary gradually transformed into a continental margin with strike-slipping faulting or transform faulting since 34 Ma.The southern margin was an asymmetric rift-type continental margin corresponding to the northern margin before 34 Ma,and became a passive continental margin during 34~16 Ma and gradually a thrusting-type continental margin after 16 Ma.Complex dynamic settings of the South China Sea have caused many controversies on their origin.The plate dynamic factors include either the Pacific Plate subduction and the indentation of the Philippine Sea Plate along the Taiwan Orogen to the east side the South China Sea,or the Indian Plate oblique subduction and mid-ocean ridge subduction to the west side.They may also be responsible for the uplifting of the Tibetan Plateau and the related extrusions of continental blocks to the north side.At the same time,the mantle dynamics of deep-seated magma underplating,delamination,mantle plume and mantle-hydrated process should not be ignored.

The South China Sea was formed in Cenozoic.Basins in the South China Sea could be divided into different types,such as continental shelf basins,continental slope basins and deep sea basins,which are closely related with the rifting and transition of the continental margins,and thus could be grouped into strike-slip-related pull-apart and extensional basins,extrusion-escape-related rifting basins,extension-and subduction-related buckling basins.They developed further into some ridge-spreading-related oceanic sub-basins in different stages.These basins were formed not under a single dynamics but under a very complex and changeable dynamics.These basins have suffered from a series of Cenozoic tectonic movements,such as the Shenhu,the South China Sea,the Dongsha,resulting in the formation and spatial-temperal migration of complex angular unconformities in these basins.Accompanying with the tectonic migrations and evolutions in these basins,faulting,magmatism,shifting of sedimentary subsidence centers and depocenters,oil accumulation and geohazards show a significant feature of jumping.The complex dynamic settings of the South China Sea have caused many controversies on their origin.The plate dynamic factors include the Pacific Plate subduction and the indentation of the Philippine Sea Plate along the Taiwan Orogen to the east side of the South China Sea,and the Indian Plate oblique subduction and mid-ocean ridge subduction to the west side.They may also be responsible for the uplifting of the Tibetan Plateau and the related extrusions of continental blocks to the north side.At the same time,the mantle dynamics of deep-seated magma underplating,delamination,mantle plume and mantle-hydrated process should not be ignored.At last,this paper proposes one strike-slipping pull-apart model to explain the onset of the South China Sea Basin which is closely related to the tectonic evolution of the Pacific Tectonic Domain.

Suspended sediment concentration(SSC),as the basis for sediment flux balance,is an important parameter in marine sedimentology.Based on the survey and hydrological observations at 10 stations in the Jinghai Bay and its adjacent waters,SSC in different layers is calculated,and the SSC horizontal and vertical distribution patterns and the transportation of suspended sediment are analyzed.Data show that SSC changes with the variation of tide current and runoff,and increases from the surface to the bottom and from southwest to northeast.The mechanism of longitudinal suspended sediment transport shows that sediments move toward the land and Wuleidao Bay where flood tide dominates,but move towards the sea near the Changhuikou area where ebb tide dominants.
