磨刀坑金矿地质特征及成因初探

Primary Investigation on the Geological Features and Formation Factors of MoDaoKeng gold mine

本文在野外地质调查和前人资料研究基础上,通过对含金断裂破碎带、矿体地质特征及矿石特征分析研究,磨刀坑为变质热液＋岩浆热液（叠加）型金矿。区内F5是金矿成矿的必要条件,即是导矿构造也是容矿构造,为矿质的运移和储存提供了良好的场所。

In this paper, on the basis of field geological survey and the predecessors＇ research, fracture fracture zone of gold orebody geological characteristics and ore features analysis and study, sharpen the pit of metamorphic hydrothermal ＋ magmatic hydrothermal type （stack） gold zone F5 is the necessary condition of gold mineralization is lead ore structure and ore, for ore migration and storage provides a good place
