宁芜地区中生代岩浆岩的成因——岩石学与Nd,Sr,Pb同位素证据

宁芜中生代火山盆地产出火山岩与侵入岩，火山岩以玄武粗安岩，粗安岩和粗面岩为主，安山岩和响岩少量，火山岩以高钾富碱为特征，已确定为橄榄安粗岩系。侵入岩以辉长闪长玢岩－一辉长闪长岩为主，以高钠低硅为特征，并有辉长岩和花岗岩产生，据地质学和Ｎｄ，Ｓｒ，Ｐｂ同位素资料，侵入岩与火山岩属同一个岩浆系列，是碱性玄武岩浆在下地壳经过轻度ＡＦＣ混合后，侵入上地壳，在轻度混染的情况下，经过以结晶分离为主的岩浆分异形     

红外,紫外及荧光分析在有机包裹体研究中的应用

本文利用红外，紫外及荧光分析方法，对岩石中吸附有机质和包裹体有机质进行了分析研究，红外分析结果表明，生油岩中的包裹体有机质有明显的石油峰，并且与吸附有机质的峰形有较大差别，紫外分析结果也表明，生油岩中两种有机质的光谱性质不一致，而非生油岩则相反，生油岩荧光光谱特征为：荧光强度大（〉４０），λｍａｘ在４５０ｎｍ左右，光谱位于蓝绿光区，演化程度属高成熟原油阶段，这些可作为评价生油潜力，演化程度的方法及     

A Study on Organic Inclusions in Clastic Reservoir Rocks and Their Application to the Assessment of Oil and Gas Accumulations

Terrigenous clastic reservoir rocks are widespread in China,and nearly all the industrial oil and gas accumulations in eastern China occur in the clastic rocks.The study shows that organic inclusions are mostly distributed in the secondary fissures and pores which were ormed in the process of oil-rock interaction,rather than in the cements or secondary enlargements. The organic inclusions are dominantly organic gas-rich or are composed of pure hydrocarbons.Homogenization temperatures range mainly from 120℃ to 130℃，which shows a relatively high maturity of organic matter.Vertical and horizontal temperature changes provide the grounds for the investigation of basin evolution and thermal fluid-kinetics-model.Fluorescence spectral characteristics o the organic inclusions indicate that oils and gases in the area studied probably have experienced two-stage or two-time migration.Micro-fluorescence rescearch is one of the effective approaches to oil/source correlation and oil migration-stage determination.The abundance and occurrence of organic inclusions is one of the indicators of oil and gas abundance and accumulation in rock layers.With the help of other informatio,organic inclusions can provide the basis for the prospective assessment of oil and gas in clastic reservoir rocks.

地震CT及其地质解释

在金川公司龙首矿东采区1 280中段井下500m深的巷道中应用地震CT技术进行寻找深部隐伏矿体的实验。波速图像表明,研究区内中西部有一高速异常区,推断为花岗岩体和含矿的超基性侵入岩体。区内还有一个横贯测区中央近东西走向的低速断裂带。这些推断结果为后期的钻探和巷道开掘所证明。     

石源龙地区岩浆岩的稀土元素和同位素地球化学

本章系统研究石源龙地区流纹质熔结凝灰岩、粒状碎斑熔岩、英安岩、星村中细粒黑云母花岗岩的铷锶同位素地质年龄，并根据锶、氧同位素和稀土元素含量讨论其地质意义     

分形几何用于岩石损伤扩展过程的研究

通过对岩石损伤扩展机理的研究，运用分形几何理论，建立了岩石损伤变量ω与分形维数之间关系。     

裂隙岩体渗流与应力耦合的试验研究

通过对较大尺寸的裂隙岩体试块进行不同侧压力和加载条件下的渗流试验结果研究，分析了裂隙岩体渗流与应力的耦合机理，得出了不同应力条件下裂隙岩体渗流量与应力成四次方的关系。并且得出并非压应力都引起裂隙岩体的渗流量减小，当裂隙岩体受平行于裂隙面方向的单向压应力时，渗流量随着压应力的增加而增加。     

杨溪岩体中黑云母的特征及其地质意义

杨溪岩体黑云母为１Ｍ型的铁质黑云母，其特征说明岩体为壳源改造型花岗岩，但有幔源物质混入。离铌钽矿化点较近的黑云母表现出明显富铝、多锰、贫镁、少硅、少钛的特点。离白钨矿矿区较近的黑云母与远离矿区的黑云母在特征上差别不大，说明杨溪岩体黑云母的特征变化对成矿影响不大，但岩浆活动是重要的成矿因素之一。     

Important Geological Factors Controlling the Formation of Gold Deposits in East China

The major gold deposits in east China are characterized by their occurrence in pre-Cambrian host metamorphic rocks,restriction in some specific stratigraphic-structural terranes,tendentious localization in ductile or ductile-brittle shear zones,association with the syntexis type granitoids,and significant remobilization,superimposition and enrichment by the later stage Mesozoic tectono-magmatic activities.
