Gravel and sand beaches, as well as mud foreshore are well developed in the coves around Zhujiajian Island, the most eastern island of Zhoushan Archipelago.The results of studying its recent coastal sediments are as follows: 1.The distribution of different beach type is controlled by the strength of wave action and the lithological characters of bedrocks.Wave energy is the strongest along the eastern coast of the island Mere, gravel beaches are formed where tuff are exposed,and sand beaches are developed in granitic terrain.Owing to the weakest wave energy,fairly wide mud foreshores are developed along the western coast.While along the northern coast, the wave energy is intermediate as compared with the eastern and western sides, the backshore and the upper part of foreshore are chiefly composed of sands, and the medium and lower parts of the foreshore are composed of silt and mud. 2.A large-scale gravel bar is formed under such a condition that the strength of wave action is strengthened whence the cove is narrowed, usually trumpet shaped, and is supplied with sufficient amount of gravels.Within fairly open cove which is subjected to moderate wave and tidal action,and whence a certain amount of gravels is available,a belted gravel beach is formed owing to the pretty well shape sorting of sedimentation. Five sub-zones have been distinguished in seaward direction, namely; 1) large disc, 2)imbricate, 3) infield frame, 4) spherical rod, and 5) outer frame zones.The beachgravels with their unique roundness and better distinguishable shape,mey be of utility in indentifying ancient beach environment.Besides, their average size may also reflect the intensity of wave action. 3.Sand beach along eastern coast are characterized in fine to very fine grains with high mineralogical maturity and very good sorting which are derived from weathering elastics of medium to fine granular granites.The mean grain size and the values of standard deviation of sands in sub-facies are not very different.They are being carried from a short distance by waves and currents.Those of northern coast are made up of medium to coarse sands with low mincralogical maturity and moderate to good sorting,which are derived from weathering elastics of coarse granular granites.There are big differences between the structural characteristics of different sub-facies.The skewness and bedding features are two combined good environmental indicators which can be used to discriminate further sub-facies either in mediumcoarse sand beaches or in fine sand beaches. 4.Tremendous amounts of suspending matlers, silt and mud, being carried by south ward longshore current issuring from Yantze River mouth and ebb tidal current from Qiantang River, are the source of mud foreshore sediments around the island.The beach patterns and their sedimentary distribution are greatly influenced by seasonal changes.It is abundant in living organisms, both in species varities and indivi-dual numbers.The sedimentary structure are strongly disturbed by those living organisms.

The effect of alkali (NaOH) on expansion of sulfoaluminate cement was studied by means of expansion test, compressive strength test and XRD as well as liquid phase analysis.The presence of NaOH increases compressive strength of hydrated pastes in early ages but decreases compressive strength in later ages.NaOH promotes the formation of ettringite in the pastes. The expansion value and ettringite content in the cement pastes increase with the increase of NaOH concentration. Even in the high concentrated NaOH solution (0.7mol/L) with pH=13.28, the ettringite formed is not amorphous but crystalline. With the increase of NaOH concentration, concentration of CaO in the liquid phase contacted with the pastes decreases while eoncentration of Al_2O_3 increases. The expansion caused by ettringite does not always depend upon the saturation degree with respect to CaO but depends on the pH value of liquid phase in which ettringite is formed. The expansion caused by ettringite formed in a liquid phase with lower CaO concentration but higher pH value is higher than that in liquid phase with higher CaO concentration but lower pH value. The higher the pH value of liquid phase, the greater expansion will be caused by ettringite.

用测量膨胀值、强度和XRD以及液相分析等方法研究了不同浓度的NaOH溶液拌和的硫铝酸盐水泥的膨胀性能。结果表明,NaOH的存在使早期强度提高而后期强度降低;NaOH浓度增加,钙矾石生成量也增加,膨胀值增大;即使在pH=13.28的液相环境中,生成的仍然是晶体而不是非晶体钙矾石;随NaOH浓度增大,液相中CaO浓度降低,而Al_2O_3浓度提高;钙矾石的膨胀值的大小不一定取决于液相中CaO饱和程度,而与液相的pH值有关,pH值越大,膨胀值越大;在CaO浓度低而pH值高的情况下,钙矾石的膨胀值比在CaO浓度高而pH值低的情况下大。

The majority of oil and gas in China and Australia formed in terrestrial sedimentary basins. Eleven oil samples collected from Eromanga Basin were provided generously by Australia Delhi petroleum Company in 1984. They were sampled from the Middle Jurassic-Early Cretaceous strata. On the basis of mass-spetrometer and capillary chromatogarphy analyses, they are characterised by paraffin-base crude oil with high ratio of pristane/phytane and heavy δ13C value. The compositions of samples are more or less alike, and carbon atom numbers of the principle peak distribute widely from C10 to C21 with a little isoprenoid and the ratios of Pr/nC17 and Ph/nC18 are 0.22-0.49, 0.04-0.09 respectively, only Brikhead oil samples of Charro have a high ratio of Pr/nC17 ( 0.74 ) . In accordance with the ratios of Pr/Ph, Pr/nC17 and Ph/nC18 the samples can be divided into three sub-groups approximately. The ratios of Pr/Ph in the three sub-groups A,B,C are 4.0-6.0, 6.0-6.5, 8.0-9.63 respectively, coinciding with the distribution pattern of hydrocarbon chromatogram. Theδ13C values of eleven oil samples range f rom-23 .53‰ to-26.24‰. A lot of scholars useδ13C (-2.6‰)as a boundary value to tell oils formed in marine environment from that in terrestrial. But geological data indicate that the samples are generated in terrestrial environment. According to the ratios of Pr/Ph, Pr/nC17 and Ph/nC18, the Chinese terrestrial petroleum can be classified into four types. TypeⅠ: The ratio of Pr/Ph is near 1.0 ( 0.87-1.39 ) with medium pristane and phytane content. The ratios of Pr/nC17 and Ph/nC18 are 0.18-0.61 and 0.15-0.77 respectively. It is generated in fresh-brackish lacustrine sediments. The majority of marine oils distribute in this range. Type Ⅱ: the ratio of Pr/Ph is less than 0.80(0.33-0.70), the phytane content is specially high, usually with predominant odd carbon numbers in lower carbon numbers, meanwhile the predominance of even carbon numbers in higher ones when phytane is regarded as a boundary. Type Ⅱ forms in saline lacustrine enviroment and some of marine crude oils formed in saline enviroment probably have this kind of characteristics. The ratio of Pr/Ph in Type Ⅲ is more than 2.50 ( 2.75-4.28 ) with very low content of isoprenoid and the ratios of Pr/nC17, Ph/nC18 are less than 0.85, 0.21 respectively. It is generated in river-lacustrine or swamp deposits. The environment of forming type Ⅳ is peaty-swamp or bog. The ratio of Pr/Ph is 7.23, while those of Pr/nC17, Ph/nC18 are 1.27, 0.18 respectively. Type Ⅲ and Type Ⅳ are similar in characteristics, however, there is a high content of isoprenoid in the latter. The value of C in the Chinese terrestrial petroleum distributes from -20‰to -32‰widely. Owing to the δ13C value of oils formed in salt lacustrine deposits and some of swamps is heavier than -26‰ as well, to authors opinion, it could not use the δ13C value (-26‰ ) to separate marine oils from terrestrial ones. However, on the basis of statistical probability, we can distinguish between fresh-brackish lacustrine and marine oils by using δ13C ( -26‰ ) as a boundary value. This paper introduces a new graph which expresses the relationship between the ratio of Pr/Ph and the value of δ13C in determining the environments of oil formation. The different regions of the graphrespcct different geochemical environments in which variant types of crude oils are generated, such as Region Ⅰ: the fresh-brackish lacustrine, Ⅱ: the salt water lacustrine, Ⅲ: the river -lacustrine, Ⅳ: the peat-bog, Ⅴ: the marine.
