石英热发光强度填图:脉金矿床深部成矿远景预测评价的新途径——以文峪金矿床研究为例

在对文峪金矿床５０５，５３０脉石英矿物热发光特征研究基础上，提出了以石英热发光总强度１０００ＣＰＳ，峰强１５０ＣＰＳ为评价石英脉含金性的定量判别标志；根据上述准则，开展了５０５及５３０脉局部范围的石英热发光强度填图工作，并得出了５０５脉１３中段及５３０脉１０中段在现在矿体深部仍有较好成矿前景的结论，为脉型金矿床深部成矿远景评价提供了新的途径。

Mapping of Thermoluminescent Intensity of Quartz: A New Path to Prognosis and Evaluation of Deep Level Mineralization Perspective of Quart z Vein Type Gold Deposit As Exemplified by Wenyu Gold Deposit

Based on study of the thermoluminescent features of q uartz from vein No.505 and No.530 in Wenyu gold deposit,the value 10 000CPS for total thermoluminescent intensity and 150CPS for thermoluminescent peak strength of quartz were proposed as quantitative indicators to evaluate the auriferous f eature of quartz veins.According to this criteria,mapping of thermoluminescent intensity of quartz on limited parts of vein No.505 and vein No.530 were carried out,and conclusions that the deep parts beneath the exsited orebodies on 13th l evel of vein No.505 and 10th level of vein No.530 still have better exploration perspectives were made.All these provide a new path to prognosis and evaluation of deep level mineralization potential for quartz-vein type gold deposits.
