古潜山火成岩裂缝带划分与孔隙度计算

针对火成岩岩性成分复杂，常规测井难以正确划分岩性，严重阻碍了储层参数的定量计算。本文提出模糊聚类划分岩性，采用综合概率法与混合体积模型计算裂缝孔隙度、有效孔隙度等参数。其测井解释结果与井壁取心和地质描述资料对照，完全吻合。

The Influence of Element Diffusion at the Sediment—Water Interface on the Basic Chemical Composition of Overlying Water Mass in Lake Lugu,China

Little work has been done on the influence of seiments on the basic chemical composition of overlying water mass.This paper deals with the vertical profile of the basic constituents such as Ca^ ,K^ ,Na^ ,and HCO3^-,as well as of pH in the overlying water mass and sediment porewater of Lake Lugu-a semi-closed,deep lake in Yunnan Province.The reand sediment porewater of Lake Lugu- a semi-closed,deep lake in Yunnan Province.The results revealed that those basic constituents may diffuse and transport from bottom sediments to overlying water mass through porewater.In the paper are also quantitatively evaluated the diffusive fluxes and the extent of their influence on overlying water mass,indicating that the lake sediment-water interface diffusion plays an important role in controlling the basic chemical composition of water in the whole lake.     

民和盆地上侏罗统湿型冲积扇沉积

本文通过岩相特征、粘土矿物分布、早期成岩矿物组合、微量元素等特征的综合分析，认为民和盆地上侏罗统下部为一较典型的湿型冲积扇沉积。冲积扇扇中发育河道冲刷充填和漫流沉积，而泥石流不发育。沉积层序与现代湿型冲积扇可对比。扇体中粘土岩及早期成岩矿物组合中富含高岭石，应与扇体发育时的潮湿气候和弱酸性流体的较强的淋滤有关。由粘土岩中微量元素因子分析进一步表明，该地层中富硼、钒的特征与相邻非扇相地层明显不同     

海南同安岭-牛腊岭火山地层划分与对比

将同安岭—牛腊岭火山地层划分为六罗村组、汤他大岭组、岭壳村组，总厚度达５４２９ｍ。六罗村组下部以玄武安山质火山岩为主，上部为流纹质火山碎屑岩、熔岩；汤他大岭组主要为英安岩类火山岩，岭壳村组为流纹岩类的岩石，构成２个喷发旋回。根据同位素年龄，确定火山岩的时代为早白垩世，与海南岛下白垩统鹿母湾组为同期产物，相当于我国东南沿海白垩纪火山岩。

Effects of convection instability due to incompatibility between ocean dynamics and surface forcings

The study demonstrates that an incompatibility between a surface temperature climatology and a given ocean model, into which the climatology is assimilated via Haney restoration, can cause model ocean climate drift and interdecadal oscillations when the ocean is switched to a weaker restoration. This is made using an idealized Atlantic Ocean model driven by thermal and wind forcing only. Initially, the temperature climatology is forcefully assimilated into the model, and an implied heat flux field is diagnosed. During this stage any incompatibility is suppressed. The restoring boundary condition is then switched to a new forcing consisting of a part of the diagnosed flux and a part of the restoring forcing in such a way that at the moment of the switching the heat flux is identical to that prior to the switching. Under this new forcing condition, the incompatibility becomes manifest, causing changes in convection patterns, and producing drift and interdecadal oscillations. The mechanisms are described.
