Gold deposits in the area of Xiao Qinling, Henan and Shanxi provinces,North China, occur in Archaen metamorphic rocks of Tai Hua group. Theseare of quartz vein type mineralization of natural gold without significant sul-phides in it. According to mineral assemblages and the characteristics of gold minerali-zation, the development of Xiao Qinling gold deposits can be divided intofour periods. Gold mineralization mainly relates to the Ⅱ and Ⅲ periods. The native gold and some other gold-bearing minerals normally exist in py-rite in form of microinclusions, or at the interstices bewteen grains of py-rite and puartz. Small amout of gold might exist in other sulphides as well. On the basis of the fluid inclusion temperature measurement and the ther-modynamic calculation, the equilibrium parameters for the mineral assemblageof pyrite, pyrrhotite, chalcocite and chalcopyrite are presented, The pres-sure conditions related to temperature of different mineralization periods areobtained. Through the calculations of the S_2, O_2 and CO_2 fugacities for sul-phides, oxides and carbonates the minimum concentrations of Fe~(2+), Zn~(2+),Pb~(2+), Au~(3+) in the ore forming solutions of each period are determined.

本文根据矿物共生组合及金矿化特征,对小秦岭金矿的形成划分为四个矿化阶段。金矿化主要呈自然金和少量其它金矿物显微包体形式,存在于各阶段黄铁矿、黄铜矿与石英晶粒间,少数产于石英或其它硫化物中。根据不同矿化阶段主要矿物的包体测温数据和包体成分的酸碱度测定位,用热力学的原理和方法,计算了小秦岭金矿床成矿的温度、压力、硫逸度、氧逸度、二氧化碳逸度,以及主要矿化离子浓度、酸碱度和氧化-还原电位等物理化学条件。

This paper describes the features of ineelastic deformation of Qianan quartzite, especially the formation process and the variation with increasing temperature and pressure.The study shows that increasing temperature and pressure is most favorable to the-transition of quartz from elastic to plastic component, which will greatly change the macrodeformation features. Once the transition of quartz reaches a certain amount, it will decrease the strength of quartzite and give rise to the instability.In order to explain the results of experiment, a series of empirical equations have been established for the P. T dependences of inelastic deformation and plastic component, for the relationship between plastic component and inelastic deformation, as well; as for the relation between the plastic component and the factor of released elastic energy.

本文通过研究地壳温压条件下迁安石英岩非弹性变形特征和机制,着重阐述了这类岩石产生非弹性变形的能力和温度压力之间的关系,以及对岩石宏观失稳型式的影响。研究表明,温度和压力的升高将导致岩石中石英晶粒逐步转化为塑性组分,转化过程中伴随着岩石宏观非弹性变形的增强。宏观非弹性变形增强幅度和微观转化为塑性组分的石英晶粒含量满足一定的统计关系。当转化的塑性组分达到一定量级时,岩石的宏观力性和失稳型式将产生明显变化,变化的趋势是易于产生非弹性变形而渐进失稳。

The results from the compared experiments show that the economical Red-silica being abundant in our country not only can take the place of expensive rare refined quartz sand for induction furnace liner,but it also has the advantage of having no crack,no dreg and easily to be cleaned on the liner.The reason why the Red-silica can resist the corrosion of acid dregs and is stable in thermal shocks is that it's silica grain is small and contains catalyst which is good for the transformation of the crystal.A further...

通过生产性对比试验证明:我国富产而价廉的红硅石生料代替稀缺昂贵的精制石英砂打结感应电炉炉衬不仅是可行的而且还具有不开裂、不挂渣和易清炉等特点.红硅石材料抗酸性氧化渣侵蚀和热稳定性优良其理论根据主要是石英晶粒细小和含有利于晶体转化的“促进剂”.在电炉炉衬上应用仍有潜力。可进一步通过实验寻找最佳方案,以扩大其应用范围.
