Twelve samples ofJiaoziyan gabbroic rocks and four Zhujiapu pyroxenites from Northern Dabie complexwere analysed for major, REE and trace elements. Major elements of gabbroic rocks show fractionalcrystallization during its magma evolution. The LREE-enriched and HFSE- depleted characters of gabbrosand pyroxenites, together with their Nd and Sr isotopes indicate the involvement of terrestrial material inmantle source, probably related to its subduction. The chemical and isotopic signals for gabbros andpyroxenites aren't correlated to oceanic ophiolitic melange, but reflect their affinity of transition fromactive continental margin to island arc magmatism.

Re, Os concentrations and Os isotopic compositions of the Dongling ⅢCD iron meteorite were determined by N-TIMS technique. The result was compared with that of the other irons and chondrites. The Re and Os concentrations of the Dongling iron meteorite were plotted on the trends of the group ⅢA and ⅣA irons. The Pt-Os relation of the Dongling iron meteorite is similar to that of the group ⅡA irons. That suggests a higher fractionation for the Dongling iron meteorite.

1 Geological setting and samples Songxi Ag-Sb ore deposit is located in the southern margin of Yongding-Mexian Paleozoic depressionof South China Caledonian orogenic belt, and the northern margin of Zhaigang Mesozoic volcanic basin,where a series of faults and folds formed with northwest tectonic directions. The sedimentary rocks arecomposed of Songling Group of low Jurassic system, Zhangping Group of middle Jurassic system and Quaternary System in which Songling Group can be divided into 3 lithostratigraphic units regionally, where thetwo of the units can be found there, i.e. the middle unit with gray-yellow quartz sandstone, fine sandstone and siltstone, and the upper with black shale and tuff, in which layered Ag-Sb ore bodies are deposited, and especially in the low part of quartz sandstone, siltstone, bioclastic limestone and the alteredbasalt are the main ore-bearing rocks. The ore bodies can be divided into two types of mineralization, i.e. bedded or bedded-like types and vein type.

Effect of dust charge fluctuations on Kelvin-Helmholtz (K-H) instability driven by sheared dust flow is investigated in magnetised three-component cold dusty plasma. It is found that the dust charge fluctuations have little effect on the tenuous dust plasma in low-frequency perturbation. For a dense dust plasma, the maximum damping rate of the perturbed wave due to dust charge fluctuations will reach the order of dusty charging frequency. It will affect the existence of the K-H instability in the long wave length perturbation.

在测量大庆油田砂岩样品纵横波速度与饱和度的变化关系中发现，在高频条件下，样品中的流体含量对横波速度基本上没有影响，而对纵波速度影响较大，并且在某一饱和度时出现波速最低值。文中引用并改进了三相介质气体包裹体模型，对上述变化规律进行了探讨，认为孔隙中流体分布的均匀性和波的频率都对波速随饱和度变化曲线有影响。数值模拟与实验的结果较为一致。
