不透明矿物所含单个低盐度流体包裹体液相组分SAM/AES实验研究:Ⅰ.原理与方法

针对与矿石矿物共存透明脉石矿物所含流体包裹体并不完全代表成矿流体，红外显微技术及EPMA、SEM等常规表面分析手段无法满足不透明矿石矿物所含单个低盐度流体包裹体研究的实际困难，本文首次成功地应用具同步扫描成象功能、电子束斑空间分辨率较高、信噪比较好的PHI595SAM／AES这一当代高灵敏表面分析技术，按单矿物分选→二次去离子水反复超声清洗→外真空热爆→在金属铟片上压制成样的实验流程对新疆阿尔泰多拉纳萨依金矿床含金黄铁矿所含单个低盐度流体包裹体的液相组成进行了静态定点分析，实验取得了满意结果。     

湖泊沉积物-水界面营养元素的生物地球化学作用和环境效应 Ⅰ.界面氮循环及其环境效应

发生在沉积物-水界面的剧烈生物地球化学作用对沉积物和上覆水体具重要的环境效应，然而此方面研究很少。本文通过云贵高原四个湖泊湖水和孔隙水NH和NO剖面，沉积物柱芯不同结合态氮含量剖面分布，界面扩散通量，影响氮循环的因素及它们季节性变化规律等的对比研究，初步揭示了湖泊沉积物一水界面的氮循环及其环境效应。     

山西奇村地热田的勘察与研究

通过近期对山西省忻州市奇村地热田进行的实地物化探勘察发现：地下热水的分布范围内视电阻率普遍偏低，且水温愈高，视电阻率愈低，在α 卡异常处均有地下热水存在。该地热田的热水分布区内的隔水层和盖层为亚粘土，粘土层。基地下热水的水化学类型为氯化物硫酸钠型及氯化钠型，热田热水赋存和滞留于浅层次生热储内。     

Behaviours of REE and Other Trace Elements During Pedological Weathering-Evidence from Chemical Leaching of Loess and Palaeosol from the Luochuan Section in Central China

The chemical leaching method is used for a systematic analysis of distribution characteristics of acid-soluble and acid-insoluble REE and other trace elements from the Luochuan loess deposits. The study shows that the acid-insoluble phase in loess and palaeosol is a stable component of old aeolian dusts and is characteristic of the provenance; the acid-soluble phase is the unstable component in the weathering pedogenic process and reflects rock-forming features after accumulation of aeolian dusts. The acid-insoluble REE and acid-soluble Sr and Pb can be used as geochemical indicators respectively to trace the provenance characteristics and the weathering pedogenic process.     

NW断裂构造──鹅公山火山盆地铀矿成矿的关键要素

鹅公山火山盆地受郯庐断裂系影响，ＮＷ断裂构造尤为特色：张扭性，倾向ＮＥ，右行下滑，对盆地中３个铀矿床及绝大多数铀矿（化）点具明显控制作用，是铀矿成矿的关键要素。研究ＮＷ断裂对在鹅公山火山盆地及其它地区找矿都具有实际意义。     

太古宙克拉通型下地壳剖面：华北怀安－丰镇－尚义的麻粒岩－角闪岩系

华北克拉通北缘晋冀内蒙交界地区有变质程度连续变化、从高压基性麻粒岩、麻粒岩到角闪岩相的变质岩系出露。它们的古变质压力由＞１．４ＧＰａ（５０ｋｍ）变化到０．５ＧＰａ（１５ｋｍ）；岩石类型从变辉长岩、中酸性正片麻岩到表壳岩变化；变质矿物组合由不含水的耐火组合变为富含云母和角闪石的组合；地球化学性质表现出从贫Ｓｉ和Ａｌ、轻度亏损生热元素到具有正常的化学成分的连续变化；包裹体流体性质在轻度亏损生热元素的麻粒岩中均为ＣＯ２流体，而在麻粒岩相的表壳岩和角闪岩系中Ｈ２Ｏ流体逐渐增加。上述变质岩系剖面的组成和特点符合大陆下地壳的定义，可能代表了包括最下部地壳在内的华北地块太古宙克拉通型大陆下地壳。据此本文建立了我国第一条克拉通型大陆下地壳剖面，并讨论其地质意义以及相关的问题

Stratigraphy of the upper cretaceous and lower tertiary strata in the Tethyan Himalayas of Tibet (Tingri area,China)

The 1500-m-thick marine strata of the Tethys Himalaya of the Zhepure Mountain (Tingri, Tibet) comprise the Upper Albian to Eocene and represent the sedimentary development of the passive northern continental margin of the Indian plate. Investigations of foraminifera have led to a detailed biozonation which is compared with the west Tethyan record. Five stratigraphic units can be distinguished: The Gamba group (Upper Albian - Lower Santonian) represents the development from a basin and slope to an outer-shelf environment. In the following Zhepure Shanbei formation (Lower Santonian - Middle Maastrichtian), outer-shelf deposits continue. Pebbles in the top layers point to beginning redeposition on a continental slope. Intensified redeposition continues within the Zhepure Shanpo formation (Middle Maastrichtian - Lower Paleocene). The series is capped by sandstones of the Jidula formation (Danian) deposited from a seaward prograding delta plain. The overall succession of these units represents a sea-level high at the Cenomanian/Turonian boundary followed, from the Turonian to Danian, by an overall shallowing-upward megasequence. This is followed by a final transgression — regression cycle during the Paleocene and Eocene, documented in the Zhepure Shan formation (?Upper Danian - Lutetian) and by Upper Eocene continental deposits. The section represents the narrowing and closure of the Tethys as a result of the convergence between northward-drifting India and Eurasia. The plate collision started in the Lower Maastrichtian and caused rapid changes in sedimentation patterns affected by tectonic subsidence and uplift. Stronger subsidence and deposition took place from the Middle Maastrichtian to the Lower Paleocene. The final closure of remnant Tethys in the Tingri area took place in the Lutetian.
