人工合成烃类包裹体的实验研究

运用 Sterner 和 Bodnar(1984)提出的愈合裂隙的实验技术,在石英中成功地合成了烃类包裹体,并对合成的包裹体进行了岩相学观察、显微温度测定及激光拉曼光谱分析等。实验揭示出除合成压力之外,合成温度、反应时间和油水比例是烃类包裹体合成时几个需要重点考虑的因素。此外,合成时加入的初始溶液盐度和酸碱度也值得进一步考虑。人工合成烃类包裹体为研究天然烃类包裹体的形成机制及测定分析奠定了基础。     

一个与峪耳崖性质相似的岩体—大野峪岩体

大野峪岩体位于喜峰口-下板城构造岩浆活动带中。该构造岩浆活动带由数条NEE—NE向区域性大断裂和沿断裂带分布的岩浆侵入体组成，按岩性和侵入的先后次序可将岩浆侵入体划分为两个岩石系列：早期超基性岩-基性岩-二长岩系列，晚期闪长岩-花岗闪长岩-花岗岩系列。它们多呈NE向展布。金矿化与晚期闪长岩-花岗闪长岩-花岗岩系列密切相关，为-构造岩浆金矿成矿带，带内分布有峪耳崖金矿、炮岭金矿等大中型金矿床及众多金矿点。     

地质雷达方法检测隧道衬砌质量研究

在铁路、公路和电站等项目的建设中,隧道隐蔽工程所占比例较大。为了严格控制隧道的施工质量,检测方法由传统的破检向无损检测转变,并对无损检测的精度要求也越来越高。由于探地雷达技术具有高效率、高分辨率和异常图像直观等突出优点,因此,该方法广泛应用于隧道隐蔽工程的质量检测中。这里从地质雷达方法原理出发,从理论上研究了电磁波在隧道衬砌内的传播规律、反射能力和基本雷达图像特征,并结合工程实例,总结了正确判识各类雷达异常的经验,提出了常用的反演计算方法。

前言：首届亚洲流体包裹体研究国际会议

ACROFI,abbreviation of the Asian Current Research on Fluid Inclusions,is a parallel of ECROFI and PACROFI.The first conference of ACROFI(ACROFI-I)was held at Nanjing University,China on 26～28 May 2006.ACROFI was designed as a biennial conference and aimed at providing an international forum for the exchange of latest researches and new ideas of geoscientists from academy,government and industry from Asian countries and other nations focusing on studies of both fluid and silicate inclusions.     

中国云南哀牢山含海蓝宝石伟晶岩的起源和成岩模拟实验研究

The Ailaoshan aquamarine-bearing pegmatites are associated with Proterozoic metamorphic rocks in the southern portion of the Ailaoshan fault-folded complex.The gem-bearing pegmatite mineralization zones of the region occur in areas generally consistent with the regional tectonic trend.The pegmatites are found in metamorphic rocks,migmatites and in the inner/outer contact zones of gneissoid granites. The Rb-Sr isochron drawn for the pegmatites is 26～31 Ma,(i.e.in Himalayan).The homogenization temperatures of melt and liquid inclusions in minerals vary from 185 to 920℃,which are comparable to the inclusions observed in banded migmatites and ptygmatic quartz veins in the surrounding metamorphic rocks. The mineralization fluids of the pegmatite were rich in HCO_3 and CO_2,and their compositional assemblages are comparable to metamorphic fluids.Results of H,O,C,Si etc.isotopic analyses and REE,and Be analyses indicates that the sources of mineralization components that formed the pegmatites are closely associated with metamorphic fluids and the enclosing metamorphic rocks. A pegmatite structure simulation experiment was conducted at high temperature and pressure(840℃and 1,500×105Pa.),with various metamorphic rock samples in a water-rich and volatile-rich environment.When the liquidus was reached,the temperature was gradually decreased at the rate of 5～10℃/day over a time period of three months.SEM energy-dispersive spectrum analyses were performed on the experimental products.A series of pegmatoid textures were observed including zonal texture,megacryst texture,drusy cavities,crystal druses,and vesicular texture along with more than ten types of minerals including plagioclase,microcline,quartz and biotite.Different metamorphic rock melts generated different mineral assemblages.Experiment results revealed that the partial melting of metamorphic rocks could form melts similar to pegmatite magmas. Based upon the geological characteristics,geochemistry,and pegmatite texture simulation experimental results,it is concluded that the mineralization components of Ailaoshan aquamarine-bearing pegmatites came from metamorphic rocks.The petrogenetic model for the origin of pegmatites is related to ultrametamorphism and metamorphic anatexis.

HBV模型在中国东北多冰雪地区的应用研究

HBV模型是瑞典SMHI开发研制的水文预报模型，广泛用于水文预报、未控制河流的流量模拟、设计洪水计算和水质研究。HBV／IHMS的积雪和融雪模型，可以模拟冰河和田间积雪区的降水量。中国东北地区有较长冰雪覆盖期，春汛预报和春季抗旱水量分析尤为重要，但是缺少考虑融雪（冰）的洪水预报方案和软件系统。利用鸟苏里江一级支流挠力河的历史水文气象资料作为实例应用HBV／IHMS，模拟效果良好，分析结果表明HBV模型对于中国东北多冰雪地区的洪水或水量预报是可行的。
