The wet deposition rate ( Fw ) of TN, NH4+- N, NO3--N, TIN, TON between atmosphere - water interfaces were measured, and the annual average Fw of TN , NH4+- N, NO3- N ,TIN ,TON was 2806. 75 kg/km2 ,1458. 81 kg/km2 ,631. 67 kg/km2 ,2090.48 kg/km2 and 716. 28 kg/km2 , respectively.
The deposition flux of sulfur (SO2+SO42- particle) was 104.6kg S/(hm2a) in 2000 and 2002 respectively, SO2 dry deposition as the main dedicator of the atmospheric dry deposition occupying 98.38% and 97.2%;
The formation of rich hydrocarbon source rocks depended on the tectonic setting of rapid subsidence, favorable paleoclimatic conditions and paleolimnology environments.
The crossflow distributions and the ground surface subsidence at various instants of time are found.
The limiting subsidence is expressed in closed form.
It should be noted that precisely these epochs were marked by a substantial renewal in faunal and floral communities, which also resulted from the new phase of the postrift subsidence.
It is shown that low heat flow, absence of progressive subsidence of the accretionary prism, open character of the system relative to water circulation, and heterogeneity of the sedimentary sequence hindered the successive development of epigenesis.
The dispersibility and electrophoretic mobility of these particles in tetrachloroethylene (TCE) have been investigated by laser particle size analyzer, static sedimentation and electrophoretic instrument.
Above the pre-Oligocene base, the estimated sediment volume is 7.01 × 106 km3 and the mass is 1.44 × 1016 t for the entire SCS, with an average sedimentation rate of 6.22 cm/ka and accumulation rate of 12.8 g/(cm2·ka) since the Oligocene.
The highest sedimentation rate and the largest mass volume occurred in the Oligocene SCS, which is quite different from global sedimentation rate patterns.
The resulting paleo-primary productivity of the ocean in end Permian south China is about 477.9 g C/m2/a during the sedimentation of cherts, which, to some extent, agrees with the primary productivity reported for some modern oceans.
Authors collected 38 sedimentary boreholes and numerous seismic profiles from previous publications to delineate the Holocene sedimentation rate of six major depositional sinks in the middle-lower Changjiang River basins and its river coast.
