柴厂金帮田的成矿作用特征

通过柴厂金矿田的地质特征及成矿作用研究，认为成矿物质主要来自深源，部分萃取自含矿围岩，矿质来源，运移通道和储矿构造扩容带是金矿成矿的主要控制因素，其中构造活动是主导性控制因素。据此提出了进一步找矿方向。     

黄铁矿表面及其与Au（HS）2^—溶液作用的STM研究

本文用ＳＴＭ研究了黄铁矿和方铅矿表面的原子结构、纳米级微形貌、电子态分布及其吸附态的特点。ＳＴＭ电流图象揭示了表面缺陷与表面电子态之间的对应关系，硫化和的表面的化学反应活性可能是表现缺陷引起的局域导电性增强有关。ＳＴＭ观察进一步表明黄铁矿和方铅矿对金的硫氢配合物的吸附作用优先发生于扭折位和台阶边缘等高能部位，反映出吸附态的分布也是与表面电子态分布相对应的。这样就从微观领域考证了硫化物表面对化学活性     

Genetic Analogy Between Sediment—Hosted Gold Deposits and Sediment—Hosted Copper Deposits in Southwest China

The sediment-hosted copper deposits according to the authors‘ study were formed from connate formation water during the post-sedimentary or diagenetic stage while the sediment-hosted disseminated gold deposits are unanimously considered to be of post-sedimentary hydrothermal origin.Therefore,apart from their own individulities.These two types of deposits must share some characters in common.Comparisons are attempted,in this paper,between the sediment-hosted copper deposits in southwest China and the Triassic sediment-hosted disseminated gold deposits in the Yunnan-Guizhou-Guangxi Triangle in terms of geological and geochemical features.     

A Study on the Geological—Geochemical Dynamics of Hydrothermal Ore Deposition as Exemplified by the Muping—Rushan Gold Deposit Belt,Eastern Shandong,China

This paper presents a method of establishing a hydrothermal ore-forming reaction system.On the basis of the study of four typical hydrothermal deposits,the following conclusions concerning geochemical dynamic controlling during hydrothermal mineralization have been sions concerning geochemical dynaamic controlling during hydrothermal mineralization have been drawn:(1)The regional tectonic activities control the concentration and dispersion of elements in the ore-forming process in terms of their effects on the thermodynamic nature and conditions of the ore-forming reaction system.(2)During hydrothermal mineralization the activites of ore-bearing faults can be divideb into two stages:the brittle splitting stage and the brittle-tough tensing stage,which would create characteristically different geodynamic conditions for the geochemical thermodynamic ore-forming system.(3)The hydrothermal ore-forming reaaction system is an open dynamic system.At the brittle splitting stage the system was so strongly supersaturated and unequilibrated as to speed up and enhance the crystallization and differentiation of ore-forming fluids.And at the brittle-tough tensing stage,the ore-forming system was in a weak supersaturated state;with decreasing temperature and pressure the crystallization of oreforming material would show down,and it can be regarded as an equilibrated state.(4)In the lates stages of hydrothermal evolution,gold would be concentrated in the residual ore-forming solution.The pulsating fracture activite in this stage led to the crush of pyrite ore and it was then filled with gold-enriched solution,forming high-grage“fissure”gold ore.This ore-forming process could be called the coupling mechanism of ore formation.     

山东文登金矿成矿动力学研究

本文通过古应力估算，流体包体研究，应变测量以及矿化蚀变规律研究，探讨了山东文登金矿的动力作用与金成矿的主要关系，认为构造动力作用的金成矿的主要原因，韧性剪切作用向韧－脆性变形作用的过渡过程是金成矿的必要条件之一。

云南腾冲热泉金的有机地球化学研究——Ⅰ生物标志物浅析

本文主要通过对比分析研究热泉软泥中的金含量与有机质及含硫化合物的相关性。并测定泉水及软泥中含金量和软泥中有机碳含量，以及对抽提物中的饱和烃和芳烃族组分进行色谱—质谱分析，最后得出的结论：有机质的沉积环境为还原—强还原，有机质属于腐泥－腐殖型，接近和达到了成熟阶段。软泥中金含量与有机质的性质无明显相关关系，与有机碳含量也无明显相关关系，而与其成熟度相关密切。样品分析证实软泥中含硫化合物与金含量呈正相关性。对比分析了水及软泥中金含量，认为两者之间也无明显相关关系
