The Beal Hornfels Deposit: A New Type of Disseminated Gold Mineralization

比尔存款的发现和开采表明，角岩矿化作为金的来源和勘探目标可能变得越来越重要。然而，含金角岩在很大程度上不为科学界所知。该研究将首先建立蚀变矿物学和容矿岩石地层学的描述基础。然后，通过对比比尔硅酸盐和钙硅酸盐矿物学与非矿化角岩晕，建立了金角岩矿化的产状模式。流体包裹体和稳定同位素分析将限制成矿溶液的流体来源、成分和温度，并允许制定具有预测能力的其他角岩系统的整体成因模型。

The discovery and mining of the Beal deposit suggests that hornfels mineralization may become increasingly important as a source of gold and as an exploration target. However, gold-bearing hornfels are largely unknown to the scientific community. The research will first establish the descriptive base of alteration mineralogy and host rock stratigraphy. Then, by comparing the Beal silicate and calc- silicate mineralogy to non-mineralized hornfels aureoles, an occurrence model for gold hornfels mineralization will be developed. Fluid inclusion and stable isotope analyses will constrain the fluid source, composition, and temperature of the mineralizing solutions and allow formulation of an overall genetic model with predictive power for other hornfels systems.
