Using the latest paleontological, magnetostratigraphic and chronological data and the lasting time of the high-resolution sequences, the authors have made a detailed chronostratigraphic division of the Jixi Group and determined the Jixi Group formed in the Early Cretaceous early Valaginian to middle Albian. In the group, the Didao Formation formed at 130.9±128.3 Ma, the Chengzihe Formation at 125.1±116 Ma, the Muling Formation at 116±106.9 Ma, and the Dongshan Formation at 106.9±101.7 Ma.

提要：利用最新的古生物、磁性地层年代资料及高分辨率层序延续时间推算，对鸡西群进行了精细的年代地层划分，确定了鸡西群形成时间为早白垩世凡兰吟早期—阿尔布中期，其中滴道组形成时间为130.9～128.3 Ma，城子河组形成时间为125.1～116 Ma，穆棱组形成时间为116～106.9 Ma，东山组形成时间为106.9～101.7 Ma。

The formation water salinity, pH value and geothermal gradient near the belt are abnormal due to mixing process according to this study. The interaction between the fluids arid the rocks assumes the process of albitization in plagioclase.

泊尔江海子断裂附近地层水矿化度pH值及地温梯度等出现异常，研究认为，造成断裂带地层水异常是由于混合作用，断裂带以外主要的流体－岩石相互反应是斜长石的钠长石化过程。

According to authigenetic mineral association and nowadays stratum geochemistry character, combining the diagenesis character of sandstone in coal measure strata, it is thought to the fluid of outcrop sandstones went through ealy acidity- acidity-alkality-surficial acidity 4 fluid phases, the fluid evolution of core sandstones is ealy acidity- acidity- nowadays alkality 3 fluid phases.

由自生矿物组合以及现今地层水地球化学特征，结合煤系地层砂岩成岩作用特征，认为露头砂岩的流体经历了早期酸性－酸性－碱性－地表酸性4个流体阶段，岩芯砂岩的流体演化为早期酸性－酸性－现今碱性3个流体阶段。

But in many reinforcement projects, some unfavourable geological are encountered frequently, such as colluvial soil, residual soil, slope wash, etc., which result in collapse of borehole and clip of bore rod during drilling of borehole that will bring considerable difficulties to construction and many incipient faults for construction quality.

但是，锚固工程常遇到各类不良地层（例如塌积、残积、坡积和崩积层等碎石土地层），在锚固施工的钻孔中由于严重的塌孔、卡钻，给施工带来很大困难，同时也给锚固工程质量带来隐患。

Basing on the analysis of epicontinental sea carbonate platform sequence stratigraphy of Cambrian in north China, the paper puts forward 6 points which shall be noticed on the study of sequence.

根据对华北地台寒武系陆表海碳酸盐台地层序地层分析，提出了露头层序工作的方法以及应注意的六项问题。

The thickness of Badong formation is approximately 820m at least and 1420m at most with a tendence of gradual incrassation from east to west.

巴东组地层在秭归、巴东、巫山、奉节等4个地区的总厚度最小约为830m，最大约为1420m，自东而西地层总厚度具有逐渐增大的趋势。

The metamorphic rocks of the area consist of granulite, plagioclase-gneis, biotite leptite and various kinds of schists of granulite to amphibolite facies By reconstruction, this metamorphic series is composed of three original formations which inciude five originai rock types: intermediate-acid volcanics formation at the bottom basic-felsic bimodae volcanits formation in the middle and basic-andesitic-felsic volcanics formation at the top...

区内太古代变质岩系广泛发育，其下部为深变质的麻粒岩相地层，上部为中深变质的角闪岩相地层，后者产出红透山式铜锌矿床多处，以及张胡子沟铜矿床和大荒沟硫铁矿床等一系列块状硫化物矿床(图1)。矿石中铅同位素年令为25～26亿年，在形成时代上可以和鞍本地区鞍山群对比。

Radiolarian-bearing strata are wide-spread in the Yarlung Zangbo Ophiolitic Complex and in the stratigraphic belt immediately to the south which is referred to as the "Northern Himalayan Subprovince of Tethyan Strata" in southern Tibet.

西藏南部的雅鲁藏布蛇绿岩带以及该带之南的沉积地层带（特提斯沉积区、北喜马拉雅亚区）中广泛发育着大量含放射虫地层。

The technologies of 90°-phase inversion,stratal slicing and interpreting with frequency are the three key technologies.

2005年2月，地震沉积学国际会议在美国休斯敦召开，继地震地层学、层序地层学之后，地震沉积学作为一门新的学科越来越受到人们的关注。

Based upon the relationship between carbonate content and stratal velocity and density, we attempted to apply the artificial neural network to the inversion of carbonate content summarized from the high-resolution seismic data limited by controlled well measurements. The method was applied to the slope area of the northern South China Sea near ODP Sites 1146 and 1148, with satisfactory results.

基于碳酸盐含量与地层速度、密度之间的关系，在井资料约束下，使用人工神经网络方法反演高分辨率地震资料所反映的地层碳酸盐含量，并应用于南海北部陆坡ODP184航次1146和1148孔区，取得较好效果。
