摘要
文峪金矿床石英热发光研究表明,含矿与无矿石英由于其构成不同,其热发光特征明显差异,含矿石英热发光曲线呈平缓开阔的弱单峰形态,峰强值低于150cps;总发光强度低于10000cps;而无矿石英热发光曲线呈中等—尖锐的单峰形态,峰强值大于150cps,总发光强度大于10000cps。上述标志对指导该区矿脉含金性评价及找矿工作均有重要指导意义。
The study on the thermoluminescent feature of quartz in Wenyu gold deposit shows that obvious differences of thermoluminescent feature exist between gold-bearing quartz and barren quartz. The thermoluminescent curves of gold-bearing quartz possess weak single peak, the peak intensity is lower than 150cps and the total thermoluminescent intensity is lower than l0000cps. However,the thermoluminescent curves of barren quartz possess middle to high single peak, the peak intensity is usually bigger than 150cps, and the total intensity bigger than 10000cos. these indicators have great directing significance on exploration and e-valuating the gold-bearing feature of mineralized veins in this district.
