摘　　要：流体包裹体爆裂法作为一种辅助找矿手段,可用于找矿勘探实践中。本文主要通过对胶东金矿矿集区内不同金矿的花岗岩围岩、蚀变岩石和含金石英脉等进行系统采样,从中挑选出符合爆裂法测温要求的石英单矿物,并对其进行了爆裂测试,重点分析了石英中流体包裹体爆裂曲线的判读要素及其地质意义,为爆裂测试结果的合理科学解释和将石英中流体包裹体爆裂法测温应用到金矿找矿勘查实践中奠定基础。As an auxiliary prospecting method,the fluid inclusion burst method can be used in the practice for ore exploration.In this paper,through systematic sampling of granite surrounding rocks,altered rocks and gold-bearing quartz veins of different gold deposits in Jiaodong gold deposit concentration area,quartz single minerals that meet the temperature measurement requirements of the burst method have been selected,and burst testing has been carried out on them.The interpretation elements and geological significance of the burst curve of fluid inclusions in quartz have been analyzed mainly.It will lay the foundation for reasonable and scientific interpretation of the burst test results and the application of the fluid inclusion burst temperature measurement method in quartz to the practice of gold ore exploration.
