摘要
山西高凡多金属矿田金银矿化脉石英的热发光曲线主要为单峰型,峰形规整对称,峰位温度270～295℃,相对峰强680～3000;铜钼矿化脉石英的大致为双峰型,峰形极不规则,具较多次级小峰,峰位温度250～370℃,相对峰强2280～3640;变辉绿岩中脉石英的呈单峰型,峰形微显,峰位温度325～340℃,相对峰强330～420。脉石英热发光曲线的峰形和相对峰强的变化特征反映了脉石英形成地质条件的复杂程度,主峰位温度的高低则基本与脉石英形成温度相当。三类脉石英的热发光特征具有一定的找矿标型性。
The results of studing the thermoluminescence of vein quartz in theGaofan polymetallic orefield show that Au-Ag mineralized vein quartzbelongs to one-peak type, its peak shapes are regular and symmetric, peaktemperatures are 270～295℃ and relative peak intensities are 680～3000.Cu-Mo mineralized vein quartz belongs to the approximate two-peak type.Its main peak shapes are irregular and contain many secondary peaks. Itspeak temperatures are 250～370℃. Its relative peak intensities are 2284～3640.The vein quartz occurring in the metamorphic diabase is the one-peak typeand shows slight peak shapes. Its peak temperatures are 325～340℃ and itsrelative peak intensities are 330～420. The variation characteristics of thepeak shape and the peak intensity of the thermoluminescent curve of veinquartz represent the complicated degree of the formation of the geologicalcondition. The main peak temperature is basically consistent with that of theformation of vein quartz. Thermoluminescence characteristics of vein quartzsof the three types possess certain typomorphic pecularities of the search forthe ore deposit.
