陕西小秦岭金矿田石英脉型金矿床石英热释光特征及其找矿意义

地下矿产信息的多源性给地质找矿勘探技术和方法的研究提供了广泛的空间。文章根据对陕西小秦岭金矿田石英脉型金矿床42件石英脉及矿化石英脉中的石英热释光测定结果的研究,发现石英热释光的发光曲线类型可以作为区分矿与非矿的评价标志:无峰型热释光曲线形态的石英脉含矿性较差;而单峰或双峰热释光曲线形态的石英脉一般为含金石英脉,是工业矿化的标志,三峰形态的石英脉含矿性最好。热释光方法作为找金矿的一种辅助手段有重要的应用意义。

Shaanxi shi-ying tian xiaoqinling gold vein type gold deposit Quartz thermoluminescence characteristics and prospecting significance

the polyphyly of underground mining information to the geological prospecting exploration techniques and methods of the research provides a broad space. Article according to the shaanxi shi-ying tian vein type gold deposits in xiaoqinling gold 42 pieces of quartz vein and mineral fossils in the vein quartz thermoluminescence determination results of research, found that quartz thermoluminescence glow curve type can be used as the evaluation marks to distinguish between mining and mining:have no the thermoluminescence peak type curve form of quartz vein ore is poorer; And unimodal or bimodal curve shape of thermoluminescence of quartz vein is commonly contain gold quartz vein, is the sign of industrial mineralization, quartz vein ore containing the best of three peaks form. Thermoluminescence method as an auxiliary means to find gold mine has important application significance.
