黄铁矿表面及其与Au（HS）2^—溶液作用的STM研究

本文用ＳＴＭ研究了黄铁矿和方铅矿表面的原子结构、纳米级微形貌、电子态分布及其吸附态的特点。ＳＴＭ电流图象揭示了表面缺陷与表面电子态之间的对应关系，硫化和的表面的化学反应活性可能是表现缺陷引起的局域导电性增强有关。ＳＴＭ观察进一步表明黄铁矿和方铅矿对金的硫氢配合物的吸附作用优先发生于扭折位和台阶边缘等高能部位，反映出吸附态的分布也是与表面电子态分布相对应的。这样就从微观领域考证了硫化物表面对化学活性     

Geochemistry of Alkaline—Ultrabasic Rocks in the Jijie Complex,Lufeng,Yunnan

is paper is concerned with the geochemical features of major elements,transition metal elements,large ion lithophile elements,rare-earth elements and Sr isotopes in alkaline-ul-trabasic rocks in the Jijie complex of Lufeng,Yunnan Province,which is located in southern Sichuan-Yunnan rift zone,one of Luoci alkaline-ultrabasic complexes in central Ynnnan,Moreover,its origin pertaining primary magma,magma soure region,fractional crystallization,etc.are also discussed in the present paper.     

地球的脉动和现阶段的扩展

脉动理论是本世纪初提出来的，最近该理论又得到了进一步的完善和发展，它可以更好地解释构造，岩浆，海平面变化，沉积作用之间的关系。地球的脉动以下列形式表现：火山作用强度，海进一步海退升，降旋回，挤压与扩展的交替、地磁场特征的变化等。     

湖南冷水江矿区障壁砂坝—泻湖—潮坪沉积体系泻湖的咸化现象

以岩石地球化学分析为基础，对测水组含煤质地层进行沉积环境参数计算，恢复沉积介质的古盐度结果表明：滨岸环境的含煤岩系形成中泻湖经历成化阶段，从而补充了以前有关泻湖的演化机制。     

山东牟平邓格庄金矿的地球化学特征及成因

邓格庄大型石英脉型金矿，分布于燕山期昆嵛山花岗岩体内金牛山断裂带次级断裂中。成矿年龄１１８×１０６ａ，它比容矿岩体冷凝至３５０℃时还晚１２×１０６ａ。成矿深度小于１ｋｍ（约０．７５ｋｍ），而容矿岩体的定位深度大于１３ｋｍ，它们的定位深度差大于１２ｋｍ。成矿流体来自地壳深部，通过水－岩反应又从容矿岩体中萃取一部分金。故此金矿不是传统意义的岩浆期后热液矿床     

地球膨胀造陆与大陆极向运动

本研究对地球起源与海陆成因及变迁等问题进行论证，以物质运动基本原理；提出：“地球中间膨胀造陆，大陆向两极移动”的新学说。认为地球成因与演变同其它天体一样，是在星际物质集中下发生的能量释主过程。由于地球水分子多，能量释放缓慢亦使陆地生成缓慢亦使陆地是其后产生的。     

黑龙江省东部跃进山群中绿片岩的地球化学特征及地质意义

跃进山群出露位于佳木斯地块和那丹哈达地体之间，是完达山造山带的组成部分。它由大陆斜坡相沉积物、大洋中脊型玄武岩和洋岛型玄武岩组成，其中有镁铁－超镁铁质岩块体。它不是一个地层单位，而是与活动大陆边缘板块俯冲作用有关的蛇绿混杂岩     

湘中雪家坡脆韧性剪切构造岩地球化学特征

在１∶５万黄材幅区调中，对脆韧性剪切构造岩进行的岩石化学、微量元素、稀土元素研究表明，由中细粒含斑二云母二长花岗岩改造为糜棱岩化花岗岩、初糜棱岩、绢云母糜棱岩、硅化糜棱岩、千糜岩、糜棱片岩等，其化学成分发生了不同程度的改变。化学元素的分散、聚集或不变，既受原岩控制（继承性），又受变形强度和流体的成分、性质、活动性等控制（变化性）。     

Geochemistry of the Rare Earth Elements in Natural Terrestrial Waters：A Review of What Is Currently Knows

The range of observed chemical compositions of natural terrestrial waters varies greatly especially when compared to the essentially constant global composition of the oceans.The concentrations of the REEs in natural terrestrial waters also exhibit more variation than what was reported in seawater,In terrestrial waters ,pH values span the range from acid up to alkaline,In addition,terrestrial waters can range from very dilute waters through to highly concentrated brines.The REE concentrations and their behavior in natural terrestrial waters reflect these compositional ranges,Chemical weathering of rocks represents the source of the REEs to natural terrestrial waters and ,consequently,the REE signature of rocks can impart their REE signature to associated waters,In addition,Because of the typical low solubilities of the REEs both surface and solution complexation can be important in fractionating REEs in aqueous solution.Both of these processes are important in all natural terrestrial waters,however,their relative importance varies as a function of the overall solution composition,In alkaline waters,for example,Solution complexation of the REEs with carbonate ions appears to control their aqueous distributions whereas in acid waters,the REE signature of the labile fraction of the REEs is readily leached from the rocks.In circumneutral pH waters,both processes appear to be important and their relative significance has not yet been determined.
