山西省五台县东腰庄金矿床石英热发光标型研究

Typomorphic study on thermoluminescence characteristics of quartz from Dongyaozhuang Gold Deposit in Wutai county,Shanxi province

石英热发光特征作为金矿找矿的重要标志,已经得到了广泛的应用。对东腰庄金矿床的石英热发光性进行了测定,对不同成矿阶段的发光曲线特征进行了对比分析,并以发光曲线峰型为参数进行了矿物学填图。结果显示:该矿床石英热发光曲线的峰型与其他矿床有明显差异,表现为单峰出现率明显低于其他矿区,接近矿体的位置单峰出现频率较高,单峰的出现指示了可能的金矿化富集部位,并预测了找矿远景区,为找矿勘查提供指示依据。

Thermoluminescence characteristics of quartz as an important prospecting indicator has been widely used. The paper carried out determination of thermoluminescence of quartz in Dongyaozhuang Gold Deposit,compared and analyzed the luminescence curves between different ore-forming phases,and charted the mineralogy based on the peak of luminescence curve. The results show that distinct from other deposits,single peak occurs less frequently in the deposit＇s quartz thermoluminescence curve; single peaks occur more frequently near the ore body; single peaks may imply the concentration of gold mineralization and indicate prospecting targets with prospects,providing basis for prospecting.
