辽宁庄河鞍子山超单元岩浆侵位变形构造

鞍子山超单元由4个单元组成，各单元不同程度地发育岩浆侵位变形构造。侵位变形构造主要由叶理构造组成，闪长质包体，钾长石斑晶总体按优选方位定向，三者产状一致，平行接触带分布。从早期单元至晚期单元，随着岩浆侵位叶理构造变形强度减弱，闪长质包体数量减少，压扁变形程度降低，钾长石斑晶从明显按优选方位定向到杂乱分布。根据上述特征，将该超单元浆侵位变形、中等侵位变形、弱侵位变形及基本无侵位变形4个带。     

烃类物质微渗漏机制及垂向运移的数值模拟

在前人烃类物质微渗漏机制研究基础上，建立了烃类物质微渗漏的概念模型，并且推导了烃类物质垂向运移的动力学模型。在动力学模型的基础上，通过数值模拟验证了烃类物质胶体气泡上升机制的合理性，并计算了不同情况下烃类物质垂向运移的平衡时间，进一步验证了烃类物质气泡上升机制满足运移速度快、流量少的特点。     

安徽铜陵冬瓜山热液叠加改造型铜矿床流体包裹体地球化学特征

研究了安徽冬瓜山热液叠加改造型铜矿床流体包裹体地球化学特征（包裹体均一温度、盐度、压力、成分、流体的H，O，C和Cu同位素），探讨了成矿流体的性质及其来源。认为该矿床是在岩浆水和后期少量大气水的加入而形成的混合热液共同作用下，活化碳酸盐岩地层和石英闪长岩中的铜等成矿元素，形成含矿热液，并以铜的氯络合物方式运移，在弱还原性条件下使原始沉积矿胚层加厚变富。     

An X-Ray Diffraction Study of an Inclusion in Diamond from the Luobusha Chromite Deposit in Tibet, China

Diamond was found in podiform chromitites of ophiolite and harzburgite from Luobusha, Tibet. There are silicate inclusions in some diamond grains from this area. In the present work, the CCD (charge coupled detector) technology of X-ray powder diffraction was applied to the study of the inclusion in diamond from the ophiolite of Tibet. Diffraction patterns are obtained even though the inclusion is only 20 μm in crystal size. The results show that the inclusion in diamond consists of talc and clinochrysotile. Therefore, it is clear that the diamond from the ophiolite of Luobusha, Tibet, is natural diamond rather than a synthetic one.     

The Role of Organic Matter During Metal Enrichment in Permian Kupferschiefer of the Rudna Mine,Southwest Poland

The bulk composition of organic matter and saturated and aromatic hydrocarbons extracted from 16 samples collected from two Kuperschiefer profiles in the Rudna mine,Southwest Poland has been analyzed to study the role of organic matter during base metal enrichment in the Kupferschiefer shale.The results indicated that the extract yields and saturated hydrocarbon yields decreased with increasing base metal contents.GC and GC/MS analyses indicated that n -alkanes and alkylated aromatic compounds were depleted and may have served as hydrogen donators for thermochemical sulfate reduction.The enrichment of base metal is closely connected with the destruction of hydrocarbons.     

Geochemical Characteristics of Gold Polymetallic Deposits as Exemplified by the Laozuoshan Deposit,Heilong jiang,China

From the studies of ore deposit geologic settings,sulfur isotopes,lead isotopes,carbon isotopes and oxygen isotopes,fluid inclusions and petrochemistry in this paper,the authors have drawn a conclusion that the ore-forming hydrothermal solutions are the high-temperature magmatic hydrothermal solutions for the gold ore deposit,and at the same time,the involvemety of crustal materials can not be ruled out .It is the first time that the authors have proposed that the Laozuoshan gold-ploymetallic ore deposit in Heilongjiang Province was formed in the calc-alkaline series environment at the margin of an active continent.     

鄂尔多斯盆地中部油气聚集区带地球化学特征研究

鄂尔多斯盆地中部存在明显的、东西方向的地球化学异常区带，异常区带有异常范围大、强度高和分布有序等特征，是地下油气信息的反映。从化探烃类指标浓度变化、比值特征和三维荧光图谱特征等方面对异常进行了研究，并结合本区的构造特征和石油地质条件对异常的形成进行了分析，证实了化探异常的形成与盆地中部的大型东西向构造带和东西向气聚集区具有密切的关系，对天然气的勘探具有参考价值。

辽河盆地东部凹陷原油的碳同位素组成特征

通过对辽河盆地东部凹陷原油的饱和烃、芳烃的碳同位素组成特征、原油同位素类型和单体烃同位素特征进行研究 ,发现整个东部凹陷原油及其组分的碳同位素值偏重 ,指示其源岩有机质中藻类和低等水生生物的贡献较少 ;饱和烃—芳烃的碳同位素值关系揭示东部凹陷大部分原油样品与沙河街组沙三段烃源岩的特征相近 ,而南部和北部地区少数样品表现出负的碳同位素异常 ,与该区中生界源岩样品的接近 ,推测原油中可能混入了中生界来源的油气。南部地区各样品的碳同位素类型曲线和单体烃的碳同位素曲线均相似 ,揭示了两者具相同的油气来源。北部地区各原油样品的单体烃的碳同位素类型曲线间具有相似的分布特征 ,但茨榆坨地区的原油样品的碳同位素值比牛居地区的系统偏轻 ,可能是成熟度相对较低引起的 ,表明茨榆坨地区原油具有早期成藏的特征。原油的碳同位素组成特征是研究油气来源和成藏特征分析的一种重要手段。     

烃类垂向微渗漏及其地表异常显示

烃类以微泡、水动力、扩散和渗透方式向地表迁移过程中,其效能、方式与油气藏的盖层、断裂与裂隙系统、储层的流体性质、地层压力等地质因素密切相关.通过对塔里木盆地雅克拉凝析气田上的地表、井中化探资料与地质资料的综合分析,认为该气田的井中垂向地球化学特征、控制烃类垂向微渗漏地质因素、地表化探异常显示之间呈现出很好的内在联系.
