新桥硫铁矿伴生金银赋存状态及分布规律

新桥硫铁矿是一大型多金属硫化物矿床 ,矿石的主要化学成分有铜、硫、铁、铅、锌 ,并伴生有以金、银、镉为主的 13种有益组分 ,其中金矿物以自然金为主 ,大部分呈细粒分散状包裹嵌布于磁黄铁矿和黄铜矿中。银矿物主要为自然银、银金矿 ,亦呈细粒分散状包裹嵌布于脉石、磁铁矿和黄铜矿中。金银在矿床中分布不均 ,在矿体走向和向深部方向局布富集有一定规律。有必要进一步圈定金、银异常区 ,进行独立金、银矿体找矿和资源预测。本矿金、银皆属难解离型 ,建议在电解粗铜中综合回收利用

The crystal chemistry and Fe<Superscript>II</Superscript>–site properties of aluminosilicate garnet solid solutions as revealed by Mössbauer spectroscopy and electronic structure calculations

The three binary garnet solid solutions Fe^II₃Al₂Si₃O₁₂–X^II₃Al₂Si₃O₁₂ (X^II= Mg^II, Mn^II, Ca^II) have been investigated by ⁵⁷Fe Mössbauer spectroscopy at 298 and 77 K and by electronic structure calculations in the local spin density approximation. The spectra yield isomer shifts and quadrupole splittings that are typical for Fe^II in the dodecahedral X-site of 222 point symmetry and are similar for each of the three binaries recorded. Conversely, electronic structure calculations based on the experimental crystal structure of the different end-member garnets exhibit pronounced variations in some of the electronic properties of Fe^II that are not reflected in the spectroscopic data. These results are interpreted as indicating that the different X–O bonds in garnet solid solutions retain to a large degree the intrinsic lengths that they possess in their respective end members, and that the Fe–O bond does not change greatly as a function of composition. This is evidence for the state of alternating bonds and not for the virtual crystal approximation in describing the X–O bond types or lengths in aluminosilicate garnet solid solutions. The observed degree and behavior of the Fe^II doublet asymmetry in the Mössbauer spectra for the three solid solution series do not indicate major variations in the anisotropic recoil-free fraction of Fe^II. Variations in doublet asymmetry are more likely a result of complex next-nearest X-site neighbor interactions and/or some degree of short-range cation ordering, though doublets representing different local X-site cation configurations cannot be resolved or fitted to the experimental spectra.

VELOCITY PROFILES OF TURBULENT OPEN CHANNEL FLOWS

1 INTRODUCTIONThe vertical velocity profile of open channel flows is the most basic infOrmation for the stUdy of flowresistance, channel bed stability, river nuvial process and sediment transport. Although it has been asubject of great interest for many years, there does not exist a consensus on some perPlexing questions,such as the position of the theoretical bed level. In order to investigate the properties of velocity profile,data measured in open channel nows from eight sources were …

含油水各向异性孔隙介质中地震波传播方程

油气勘探的重点是寻找油气储层的分布 ,而地下油气的存在必然对地震记录产生影响。传统的地震波理论是建立在纯弹性固体基础之上 ,没有考虑固体中所含的流体 ,因此 ,它难以研究含油水岩石的物理性质 ,如岩石的渗透率和孔隙度、油水粘度。从固、液介质系统能量和本构方程出发 ,推导出固体、油相和水相的动力学方程 ,进而建立起含油水两相流体各向异性孔隙介质的地震波传播方程。该方程包括有岩石和油水的物理参数 ,更适合于油田的勘探和开发。
