水口山Pb－Zn－Au矿田含矿流体的性质、来源及其环流历程

在矿床地质研究的基础上，从矿物包裹体的显微岩相学、均一化温度、成分、含盐度和Ｈ、０、Ｃ稳定同位素组成方面，探讨了水口山Ｐｂ─Ｚｎ─Ａｕ矿田含矿流体的性质、来源及其环流历程。含矿流体系由岩浆期后热液和地下水混合而成。对于水口山矿区而言，岩浆热液起着主导作用；对于康家湾矿区而言，岩浆期后热液和地下水热液均起着重要作用。热液成矿期从早到晚，随着温度和含盐度的逐渐降低，地下水中雨水／地层卤水的比值逐渐增大。含矿流体的环流历程经历了５个阶段。

Fluid Inclusion Geochemistry of Metallic Ore Deposits in the South- Central Sector of theDa Hinggan Mountains in China

Physicochemical parameters of mineralization such as temperature, pressure, salinity, density, composition and boiling of ore fluids as well as pH, Eh, fo2 and reducing parameter in theprocess of mineralization of major ore deposits in the study district have been obtained by the authors through systematic observation and determination of characteristics and phase changes of fluid inclusions at different temperatures and analysis of gaseous and liquid phase compositions of the inclusions, thus providing a scientific basis for the division of mineralization-alteration stages, types of mineral deposits and minerogenetic series and the deepening of the knowledge about the ore-forming processes and mechanisms of mineral deposits. It is indicated that the deposits of the same type have similar fluid inclusion geochemical features and physicochemical parameters though they belong to different minerogenetic series, while the compositions of inclusions are not conditioned by deposit types but closely related to     

Stable isotope characteristics and origin of ore-forming fluids in copper-gold-polymetallic deposits within strike-slip pull-apart basin of Weishan-Yongping continental collision orogenic belt, Yunnan Province, China

More than 140 middle-small sized deposits or minerals are present in the Weishan-Yongping ore concentration area which is located in the southern part of a typical Lanping strike-slip and pull-apart basin. It has plenty of mineral resources derived from the collision between the Indian and Asian plates. The ore-forming fluid system in the Weishan-Yongping ore concentration area can be divided into two subsystems, namely, the Zijinshan subsystem and Gonglang arc subsystem. The ore-forming fluids of Cu, Co deposits in the Gonglang arc fluid subsystem have δD values between −83.8‰ and −69‰, δ¹⁸O values between 4.17‰ and 10.45‰, and δ¹³C values between −13.6‰ and 3.7‰, suggesting that the ore-forming fluids of Cu, Co deposits were derived mainly from magmatic water and partly from formation water. The ore-forming fluids of Au, Pb, Zn, Fe deposits in the Zijinshan subsystem have δD values between −117.4‰ and −76‰, δ¹⁸O values between 5.32‰ and 9.56‰, and Δ¹³C values between −10.07‰ and −1.5‰. The ore-forming fluids of Sb deposits have δD values between −95‰ and −78‰, δ¹⁸O values between 4.5‰ and 32.3‰, and Δ¹³C values between −26.4‰ and −1.9‰. Hence, the ore-forming fluids of the Zijinshan subsystem must have been derived mainly from formation water and partly from magmatic water. Affected by the collision between the Indian and Asian plates, ore-forming fluids in Weishan-Yongping basin migrated considerably from southwest to northeast. At first, the Gonglang arc subsystem with high temperature and high salinity was formed. With the development of the ore-forming fluids, the Zijinshan subsystem with lower temperature and lower salinity was subsequently formed.

塔里木盆地哈得4油田成藏年代学研究

哈得4油田是近年来在满加尔凹陷北部发现的第一个海相油田，一直被认为是喜山期形成的油藏。然而，根据包裹体测温、伊利石K／Ar同位素测年以及油气水界面追溯等多种方法对其成藏年代重新研究表明，该油田主力油藏石碳系CⅢ油藏主杰晚海西期形成的古油藏，C5薄砂层油藏则可能为喜山期由CⅢ油藏垂向调整形成的次生油藏。     

金刚石伴生矿物中的烃类包裹体问题(英文)

首次在Mir金伯利岩筒中的锆石中发现了烃类包裹体。利用低温荧光光谱仪测定出烃类包裹体的成分为萘和菲的同系物 ,芘 ,1,12苯并芘等 ;其成分与Udachnaya岩筒中的橄榄石内的烃类和Mir岩筒中的石榴石中的烃类的成分相近。测定出锆石的δ13C值为 - 2 1 83‰～ - 3 3 5 4‰ ,与用榴辉岩共生组合中最轻的金刚石测出的同位素δ13C值范围相符。文中引述了有关有机物来源的讨论及多环芳烃 (PAH)由缩聚作用形成的论述。伴生矿物中相当数量的PAH的存在证明在形成金刚石及其伴生矿物的情况下 ,若有相当浓度的自由氢存在则可能发生缩聚作用。这些缩聚作用中碳的来源显然与形成金刚石时碳的来源是相同的 (即液态的CH4,CO及CO2 )。
