1中亚金-汞矿床:矿床类型 分布规律 成因模式显示文摘金-汞矿化代表一种新的有前途的矿床类型,可划分四种成因模式:Au-As-Hg,Au-Sb-Hg,Au-Te-Hg和Au-Cu-Hg,与不同金矿化有成因联系,由不同的成矿系列产生。四类金-汞矿床广泛存在于东亚和东南亚。越南是最有希望发现这一工业类型矿床的地区之一。A.S.波利申科 E.A.纳乌莫夫 G.G.巴甫洛娃 M.弗拉多泽尼 卞善涛(译) 蒋琪(译) 2006云南地质2006,25,1:6
2重新审视历史进步观念显示文摘西方知识传统中的基本哲学假定,即宇宙伦理意义的确定性,在19世纪崩溃了。作为历史运动的科学解释,作为一个普遍观念,进步观念遭到质疑。然而在特定范围内,人的行动能够创造更为合理的条件,进步观念仍然存在理性的基础。撇开其充当的关于历史本性的认知理论的角色,进步观念也必须被看作是一种伦理假定,它理性地或信仰地认可正面价值的真实性与理性行动的意义。G.G.伊格尔斯 张文涛 2009山东社会科学2009,,2:6
3The Virtual Geoscience Workbench, VGW: Open Source tools for discontinuous systems显示文摘In 1989 work began on merging finite and discrete elements. During 1990 algorithmic solutions for the new combined method were developed, together with a C-based implementation known as the Y code. In 2004 these developments and implementations were published as a textbook. Queen Mary University of London (QMUL) and Imperial College are currently engaged in a research project to make Y codes in both 2D and 3D available in Open Source format and with mainly geoscience problems in mind. The result is a set of Open Source tools for Geoscience (VGW), key components of which are summarised in this paper, together with illustrative range of simulation results.A. Munjiza J. Xiang X.

4Study on kinetics of thermal decomposition of low LOI goethetic hematite iron ore显示文摘In the present study, the kinetics of thermal decomposition of hydrated minerals associated in natural hematite iron ores has been investigated in a fixed bed system using isothermal methods of kinetic analysis. Hydrated minerals in these hematite iron ores are kaolinite, gibbsite and goethite, which contribute to the loss on ignition(LOI) during thermal decomposition. Experiments in fixed bed have been carried out at variable bed depth(16, 32, 48 and 64 mm),temperature(400-1200 ℃) and residence time(30,45, 60 and 75 min) for iron ore samples. It is observed that beyond a certain critical bed depth(16 mm), 100% removal of LOI is not found possible even at higher temperature and higher residence time. Most of the solid-state reactions of isothermal kinetic analysis have been used to analyze the reaction mechanism. The raw data are modified to yield fraction reacted 'α' versus time and used for developing various forms of 'α' functions.f(α) is the inverse of first derivative of g(α) with respect to α. The study demonstrates that decomposition of hydrated mineral in hematite follows the chemical kinetics.The estimated activation energy values in all the experimental situations are found to high, of the order of 60 kJ/mol, reinstating that the reactions are indeed controlled by moving phase boundary and random nucleation.Beuria P.C.
