脉石英

Between east and west, the mineralization in subalkalic intrusive complex is different. In the west, the veins are chiefly quartz veins, quartz veinlets and network veins, the wall rocks are mainly syenite and quartz monzonite. In the east, the fine quartz network veins, altered kata-rocks, alkali-syenite and syenite are dominant.

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 e...

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。
