摘要
祁雨沟爆发角砾岩型金矿不同成矿阶段和主成矿阶段不同标高石英中的流体包裹体具有重要的标型意义。本文从7个方面系统地总结了包裹体特征随时间演化的趋势及包裹体特征的空间变化,提取出关于矿床的岩浆热流体沸腾—爆破作用、介质物理化学性质的变化以及天水对成矿过程的影响等成因信息,提出了指导找矿的包体矿物学标志。文章还对爆裂频率曲线的标型意义进行了初步讨论。
The important typomorphic significance of the fluid inclusions in quartz of different mineralization stages and different levels of the Qiyugou explosive breccia type gold ore deposits is recognised. In this paper, the authors systematically summarize the temporal evolution trends of the fluid inclusion characteristics in seven aspects and their spatial change. Some genetic information such as the boilling-explosion of the magmatic-hydrothermal fluid, the variation of the physico-chemical nature of the metallogenic medium and the effection of meteoric water on the ore-forming process are drawn out. A couple of fluid inclusion guides for prospecting of Qiyugou type gold deposits are established. A primary discussion is made on the typomorphic significance of the explosive frequency curves of quartz.
