In this field observation we also find an important fact that , even during storm surge period , high tidal flat can still be in sedimentation in some place , no erosion occurred . to tell the typhoon storm surges from cold wave storm surges , 12 monthly sedimentary samples are collected from the modern tidal flat surface at dafeng , jiangsu . palynological analysis of these samples indicates that the seasonal palynological features of the tidal flat sediment are very obvious and some palynological indexes , such as taxon percentage of arboreal , herbaceous pollen and spore , are good indicators to tell the seasonality of the tidal flat deposits 为区分风暴潮沉积是由台风引致还是由寒流或冷锋引致，对长期处于淤积状态的江苏中部大丰县斗龙港附近潮滩，采集了一年中每月小潮期间滩面表层泥样，并在启东茅家港滩面分别采集了6月、 9月与12月的表层泥样，在实验室中，对这些样品进行孢粉等分析，认为在以粉砂、泥为主的潮滩沉积中，孢粉种类百分比，尤其是木本种类占孢粉总种类的百分比是判别季节性潮滩的重要指标，通过启东茅家港工程建设区淤积状况的观测记录对这一判别指标进行了验证。
( 2 ) the conception of the danxia landfonn that is a kind of the red clastic rock ( silthstone - conglomerate stone ) landfonn , derived of the of work the exogenetic and endogenetic force , characterized by red cliff , fortress , pagoda , wall , peak cluster , peak forest , etc . this article systematically summarized the evolvement , type and character 其次，界定了丹霞地貌的概念，丹霞地貌是发育在以红色粉砂- -砾岩为主的地层中，受内力、外力(重力崩塌、风化、流水等)作用形成的地貌，具有赤壁丹崖、方山、岩堡、岩塔、岩墙、孤峰、群峰等特征。
Three principal factors had been produced using the first derivative of the sediment reflectance as variables by factors analysis method , which indicate three kinds material source that are finer grain terrigenous sediment ( fine sand and silt ) , terrigenous carbonate and biologic carbonate respectively . the trends of traveling and enriching that material sources had given 以反射率一阶导数为变量，利用因子分析方法得到3个主因子，分别代表了研究区三种物质来源，即细粒的陆源物质(细砂及粉砂粒级) 、陆源的碳酸盐物质和生物碳酸盐物质，同时给出了三种物质来源的运移和富集趋势。
Layers of carbonate limestones , silty mudstones , quartz sand and solidified lava show that within the past 600 million years , this area was a warm , shallow sea , then a muddy swamp , then a vast desert of shimmering hot dunes , then a glacial ice sheet , then a shallow sea once again 层层的碳酸石灰岩、粉砂质泥岩、石英砂和凝固的熔岩，显示在过去六亿年间，这个区域曾经是温暖的浅海，接著依序变成泥泞的沼泽、拥有炙热沙丘的广阔沙漠，然后是冰川，后来又再度成为浅海。
In order to direct the water to the forebav of the pump station from the original canal , a channel long 135 m is designed . it crosses through the terrain top with a depth of more than 50 m . soil of the channel slopes is a strongly - weathered silty and sandy mudstone with many well - developed reticular cracks and takes the structural surfaces almost same as the channel slopes 东深供水工程金湖泵站位于塘厦镇东面，属低山、残丘地貌，地面高程22 60m ；泵站前池进水渠横切山脊，连接原东深供水河，设计开挖1条长135m的进水渠，坡高50多米，边坡土质为强风化的粉砂质泥岩，网状裂隙发育，结构面基本与坡面重合；坡体土质中含有较多的粘土矿物，具有遇水软化的特性。
The influences of soil structure , confining pressure and strain amplitude on dynamic properties of recently deposited soils of nanjing and its surrounding areas are discussed . furthermore , based on test results and theoretical analysis , the averaging curves , recommended values and envelopes of dynamic shear modulus ratio ggmax and damping ratio versus dynamic strain for recently deposited soils of nanjing and its surrounding areas are presented . by use of vibration triaxial apparatus , nanjing silty clay and fine sand interbedded strata and nanjing fine sand were tested and their test results are discussed 通过自振柱试验，探讨了土的结构性、有效围压和应变幅值大小对动荷载作用下南京及其邻近地区新近沉积土的动剪切模量、阻尼比和应力?应变关系的影响；通过试验和理论分析，给出了南京及其邻近地区的粘土、淤泥质粉质粘土、粉质粘土、粉质粘土与粉砂互层土、粉土以及砂土等六类新近沉积土中典型土类的动剪切模量比和阻尼比随剪应变幅值变化的平均曲线、包络线和推荐值。
