A marine stratigraphic sequence across the Pliocene / Pleistocene boundary has been found in the north-ern continental shelf of the south china {2.. The marine Quaternary deposits in the Yinggehai Basin may ex-ceed 2.000 m in thickness, probably providing the best section for studying the lower boundary of the marinePleistocene in south china. The vertical succession with planktonic foraminifers and nannofossils revealed inboreholes in the basin has been well correlated with that in the international stratotype section of thePliocene / Pleistocene boundary at Vrica, Italy, resulting in the acquirement of a biostratigraphic boundary at1.64 Ma. This boundary, however, does not coincide with any prominent lithological palaeoenvironmentalchanges in the study area and can hardly be used in geological practice. There are, in contrast, significantchanges at the level of LAD of Globorotalia multicamerata sensu lato located below the above-mentionedboundary. The percentage of planktonic foraminifers in the total population and preservation of foraminiferaltests display great changes at this level corresponding to a clear onlap on the seismic profiles and indicating adepositional hiatus at ca. 2.0-2.5 Ma. Since the level can be widely traced in the Pearl River Mouth Basin andthe Beibu Gulf Basin and well corresponds with the marked depositional environmental changes recorded inthe west Pacific and other regions, it is recommended that the Plio / Pleistocene boundary be drawn at the levelof Gr. multicamerata sensu lato LAD, roughly concurrent with the Gauss / Matuyama turn.

1998-1999年及2.01-2.02.对北部湾海域进行了6个航次生态环境综合调查。利用调查资料,以种为聚类变量进行了毛颚类的组群分析,结果表明北部湾毛颚类可分为3个组群。组群I及组群II为北部湾的主要组群。组群III组成种类和出现数量最少,为次要组群。组群I是一类分布广但适温盐范围较低,与北部湾高温、低盐的沿岸流关系较为密切的组群;而组群II则适温盐范围较高,与北部湾高温、高盐的外海水关系较为密切。

Using the collected 433 heat flow values,we estimated the bases of methane hydrate stability zone (BHSZ),in northern south china {2.(NSCS).Through comparing BHSZs with the depths of bottom simulating reflectors(BSRs),in Shcnhu Area(SA),we found that there are big differences between *** the north of SA,where the water depth is shallow,many slumps developed and the sedimentation rate is high,it appears great negative difference(as large as -192.).However,to the southeast of SA,where the water depth is deeper,sedimentation rate is relatively low and uplift basement topography exists,it changes to positive difference(as large as +45%).The differences change so great,which haven’t been observed in other places of the *** considering the errors from the process of heat flow measurement,the BSR depth,the relationship of thermal conductivity with the sediments depth,and the fluid flow activities,we conclude that the difference should be not caused by these *** big disagreement may be due to the misunderstanding of *** deviant "BSRs" could represent the paleo-BSRs or just gas-bearing sediment layers,such as unconformities or the specific strata where have different permeability,which are not hydrate-related BSRs.

Quaternary buried ancient river channels are widespread in the shallow-level sediments of the northern shelf of the south china {2.. The sedimentary sequence mainly of fluvial deposits comprise an important component part of the low-stand system tract and transgressive system tract in the study region. The plannar variation and spatial association of the sedimentary features such as incised valley fillings, deltaic foreset wedges and block slides of shelf-marginal fans reflect the palaeogeographic environment during the fall of the regional {2. level in the northern part of the south china {2.. Based on the high-resolution seismic reflection data and gelogical data from boreholes, the present paper makes an integrated interpretation of the Quaternary ancient river channels in the shallow sediments of the study area, studies the sedimentary features of the ancient channels such as their spatial distribution, seismic facies reflection indicators, sedimentary facies and sand -body types, and discusses their formational setting and evolutionary model, with the main purpose to render a service to the hydrocarbon resources exploration and development and marine engineering in the northern shelf of the south china {2..

Al-Si metal matrix composites (MMCs) reinforced with 2. vol.% alumina-silicate shot fibers (Al2.3-SiO2.sf)) were fabricated by an infiltration squeeze method. Pure pr metal was added into these composites. The effect of pr addition on the microstructure evolution of Al-Si MMCs was investigated by SEM,TEM,and EDS. pr addition is favorable to make uniform microstructures with the modified eutectic Si crystal. prAlSi phase with high contents of pr and Si is observed on the interface between the fiber and the m...
