吐哈盆地侏罗系砂岩储层中粘土矿物组成和分布的控制因素

在大量分析数据基础上，总结了吐哈盆地侏罗系砂岩储层中粘土矿物组成及其在纵横向上的分布特征，重点对吐哈盆地侏罗系岩储层中粘土矿物组成和分布的主控因素进行了分析，笔者认为吐哈盆地的成岩过程中砂岩孔隙介质条件，不同沉只环境砂体渗滤条件的差异，盆地的大地构造背景和构造发育史以及盆地演化过程中的古气候变化等是影响盆地砂岩粘放物组成和分布的主控因素。由此可以为寻找有利储层和设计酸化采油方案提供重要的依据。

准噶尔盆地与吐哈盆地侏罗纪沉积边界的探讨

关于准噶尔盆地与吐哈盆地侏罗纪的沉积边界问题，争论历时已久。总的来说，构造上分歧不大，而沉积上则各抒己见．为全面而系统地解决这些问题，更好地指导准噶尔盆地与吐哈盆地的侏罗系勘探及两个盆地的地质类比，本文通过博格达山南北缘侏罗沉积相、古流向及物源等方面的实地测量和分析，同时结合区域构造背景，对准噶尔盆地与吐哈盆地侏罗纪沉积边界作了进一步探讨，认为准噶尔盆地与吐哈盆地至少在侏罗纪沉积之前已被博格达山分隔开，从而开始了各自的沉积构造演化史。

吐哈盆地侏罗纪煤系源岩芳烃组成及生源、环境意义

本文系统分析了吐哈盆地侏罗纪煤系源岩的芳烃分布特征。结果表明，吐哈盆地煤成油形成于特殊成煤环境，其有机质主要来源于高等植物，但也有藻类等低等水生生物的重要贡献，沉积环境主要为湖泊-沼泽相，淡水-半咸水介质，弱还原-还原环境。     

盆地构造图三维可视化系统开发的实例介绍

传统的二维构造图难于直观地描述地质构造的空间形态。综合利用VB、VC和OPENGL环境设计的盆地构造图三维可视化系统将构造图上涉及的要素分成点、线、面、区等不同类型,每个类型数据又都由空间数据和属性数据两部分组成,并用数据库方式管理这些数据。系统除了可将各构造要素以三维方式显示外,还可以利用测井数据和剖面图恢复三维地层;同时允许用户与屏幕图形进行交互,从而实现对图形的切割操作。显示成果可以以栅格图形或AVI录像形式输出。通过几个用该系统输出的三维构造图的实例说明该系统基本能满足盆地构造图三维显示的需要。

Définition d'une limite multicritère ; stratigraphie du passage Campanien–Maastrichtien du site géologique de Tercis (Landes,SW France)Definition of a multi-criteria boundary; stratigraphy of the Campanian–Maastrichtian interval of the geological site at Tercis (Landes,SW France)

Lithostratigraphy, physicochemical stratigraphy, biostratigraphy, and geochronology of the 77–70 Ma old series bracketing the Campanian–Maastrichtian boundary have been investigated by 70 experts. For the first time, direct relationships between macro- and microfossils have been established, as well as direct and indirect relationships between chemo-physical and biostratigraphical tools. A combination of criteria for selecting the boundary level, duration estimates, uncertainties on durations and on the location of biohorizons have been considered; new chronostratigraphic units are proposed. The geological site at Tercis is accepted by the Commission on Stratigraphy as the international reference for the stratigraphy of the studied interval. To cite this article: G.S. Odin, C. R.

Quaternary stresses revealed by calcite twinning inversion: insights from observations in the Savonnières underground quarry (eastern France)

Calcite samples were extracted both from the rock matrix and the superficial coating of a karstified fault plane of an underground quarry, located in the eastern border of the Paris basin. The karstification is dated as Quaternary. Analysis of mechanical calcite twinning reveals that only the calcite matrix has also undergone a compression trending WNW that can be attributed to the Mio-Pliocene alpine collision. Both coating and matrix have undergone a strike-slip regime with σ₁ roughly trending north–south, that could correspond to the regional present-day state of stress, a strike-slip compression rather trending NNW, modified by local phenomena.
