江西凤凰岽含锡黄英岩脉特征及成因

江西会昌县岩背火山盆地密坑山含黄玉花岗岩体的北侧外接触带，产有数条含锡黄英岩脉。据野外产状、岩石结构构造等表明岩脉属岩浆成因。稀土元素研究表明，凤凰岽黄英岩ＲＥＥ含量极低，∑ＲＥＥ及配分曲线与脉侧黄玉石英化蚀变岩有着明显的区别。富氟花岗岩浆结晶晚期衍生的富Ｓｉ，Ａｌ，Ｆ含少量Ｋ，Ｎａ的残余熔浆沿断裂上侵因压力降低产生二次沸腾，使Ｋ，Ｎａ分离进入含水相，这是富Ｓｉ，Ａｌ，Ｆ；极贫Ｋ，Ｎａ的黄英岩形成的决定因素。

本文导出了电阻率-孔隙度、电阻率-含油（气）饱和度关系的一般形式--两个对称的表达式,并给予了实验证明。同时,本文指出,Archie公式、Winsauer公式和双水公式都是一般形式在一定条件下的特例。在一般情况下,本文给出了14个能够逼近这两个表达式的函数类型,通过岩芯数据进行选优,可以得到适合不同地区或地层的最优方程。根据本文理论建立的解释方法和研制的软件已经在油田生产中推广应用并取得了良好效果。 由于涉及内容较多,全文分两部分撰写。以下是本文的第（Ⅰ）部分,即一般形式的导出及实验验证;而最佳函数类型的确定及其在生产中的应用将作为本文的第（Ⅱ）部分发表。     

A note on the characteristics and possible origins of desert varnishes from Southeast Morocco. A reply to comments by R. I. Dorn

This reply to Dorn (1989) argues that a biotic origin is not the only way in which desert varnishes may be formed. It is suggested that a variety of initial conditions may result in similar end products. It is agreed that the dissimilar views of the authors may result from their different philosophies concerning the classification of Mn/Fe varnishes.     

Nonequilibrium thermodynamics of pressure solution

This paper is concerned with the thermodynamic theory of solution and precipitation processes in wet crustal rocks and with the mechanism of steady pressure-solution slip in contact zones, such as grain-to-grain contacts, fracture surfaces, and permeable gouge layers, that are infiltrated by a mobile aqueous solution phase. A local dissipation jump condition at the phase boundary is fundamental to identifying the thermodynamic force driving the solution and precipitation process and is used here in setting up linear phenomenological relations to model near-equilibrium phase transformation kinetics. The local thermodynamic equilibrium of a stressed pure solid in contact with its melt or solution phase is governed by Gibbs's relation, which is rederived here, in a manner emphasizing its independence of constitutive assumptions for the solid while neglecting surface tension and diffusion in the solid. Fluid-infiltrated contact zones, such as those formed by rough surfaces, cannot generally be in thermodynamic equilibrium, especially during an ongoing process of pressure-solution slip, and the existing equilibrium formulations are incorrect in overlooking dissipative processes tending to eliminate fluctuations in superficial free energies due to stress concentrations near asperities, defects, or impurities. Steady pressure-solution slip is likely to exhibit a nonlinear dependence of slip rate on shear stress and effective normal stress, due to a dependence of the contact-zone state on the latter. Given that this dependence is negligible within some range, linear relations for pressure-solution slip can be derived for the limiting cases of diffusion-controlled and interface-reaction-controlled rates. A criterion for rate control by one of these mechanisms is set by the magnitude of the dimensionless quantityk/2C _pD, wherek is the interfacial transfer coefficient, is the mean diffusion path length,C _p is the solubility at pressurep, andD is the mass diffusivity.     

新的引潮位完全展开

Doodson进行引潮位展开时的原始数据采自Brown及Newcomb表,其黄赤交角系采用1900年1月1日之值。目前Brown系数已重新计算,黄赤交角每世纪相对变化5×10^{-4;地球轨道偏心率每世纪相对变化25×10-4。由此引起的潮波振幅长趋势变化已可辨别,这就是所谓潮波振幅的时间依赖问题。作者采用EJC表及2000.0年的黄赤交角和地球轨道偏心率数值,重新用计算机演绎了引潮位展开式,解决了时间依赖问题。文中给出了属于J2000.0系统的引潮位完全展开表。}

莺－琼盆地YA13－1气田热流体活动与有机／无机成岩响应

根据钻井中途测试（ＤＳＴ）、重复地层测试（ＲＦＴ）、镜质体反射率（Ｒ０）、流体包裹体分析和粘土矿物Ｘ射线衍射全定量分析等综合研究发现，莺－琼盆地ＹＡ１３－１气田存在４期热流体活动；南侧的崖南地区和西侧的莺歌海盆地是其两个重要的热流体物质源和动力源；多期热流体活动在ＹＡ１３－１地区不仅造成热异常和物质迁移，而且还引起了不同的有机／无机成岩响应，如骨架颗粒的多期溶蚀作用、至少两期的次生加大作用、粘土矿物转化和有机质热成熟作用异常。第二、第三期热流体因出溶作用形成ＹＡ１３－１气田大规模的天然气聚集。     

地球油气资源潜力是自然科学的基本问题

层序地层学自１９８７年问世以来，在国外如火如荼地发展起来，石油地质界对它的发展尤为关注。然而，在我国却显得举步维艰，进展缓慢。本文讨论了出现这种状况的起因：①不认识地震反射界面基本上是等时面；②认为地震／层序地层学是研究被动大陆边缘海相地层产生的，不适于非海相地层；③常规剖面中的地震反射频率和分辨率太低，不足以进行层序地层学研究；④层序地层学属纯理论科学，脱离油气勘探实际，采纳它的概念可能打气生产秩序。最后文章从正面阐述了开展层序地层学研究的必要性。
