摘　　要：为了探讨矿床中石英与金矿化在时空上的关联 ,利用成分分析、X光衍射、红外光谱和热释光谱线特征分析等手段对其进行了详细研究。第二和第三阶段石英与金矿化关系最为密切 ;石英所含杂质越多 ,体晶胞参数越大 ,Au含量越高 ;成矿溶液介质以大气降水为主 ,K+、Na+、Cl- 、SO2 - 4为其主要成分 ;2 50～ 30 0℃区间的发光峰以第二和第三阶段的石英较为突出 ,发光强度最大。这些为研究矿床成因和找寻新的金矿点 (带 )提供了重要信息。By means of composite analyzing,X ray diffraction, infrared spectroscope and thormoluminescence etc ,this paper discussed space time relationship between gold mineralization and quart of Huangsha gold deposit in Jiangxi province in detail. The results show that the second and third stag's quart are closely related with gold mineralization.The more admixture quart contains and the greater volume of unit cell of quart,the higher gold in quart.Mineralizating fluid is mainly derived fom precipitate water,and K +,Na +, Cl - and SO 2- 4 are superiority in the fluid.The peaks of luminous intensity of the second and third stage's quart are the strongest in range of 250～300℃. These data can provide important information for researching origin of this deposit and finding new gold deposits.
