| 摘 要： | 流体包裹体研究发现,成矿溶液高浓度聚集区,常是矿床的主(富)矿体赋存处。用热爆法打开包裹体提取成矿溶液,以电导度度量其相对浓度,以地质类比法通过从已知到未知的分析,将其结果用于成矿找矿试验。实践证明,该方法在以下几个方面具有应用前景:(1)查找成矿断裂,优选最佳成矿区段;(2)区分有无工业价值的含金石英脉;(3)反映矿段或矿体的贫富程度;(4)评定矿体的稳定性或矿化不均匀性;(5)评估矿脉的剥蚀程度;(6)矿脉深部成矿预测.

| Abstract: | By the studies of the fluid inclusion, it is found that the high concentrated areas of the ore-for ming solution are generally where the main (rich) orebodies occur. Open the fluid inclusion by heat explosion, extract the ore-forming solution, measure the relative density of the ore-forming solution through its electric conductivity, and apply the results to the test of mineralization and ore-search by geological analogy. It is proved that the electric conductivity of ore-forming solution can be used to seek for ore-forming fractures, to select the best mineralization section, to distinguish industrial and non-industrial auriferous quartz veins, to reflect the rich or poor levels of orebodies, to evaluate the stability of orebodies, to judge the denuding levels of ore veins, and to prospect the mineralization in depth. |
