摘要
本文将原生金矿床的找矿标志归纳为矿源层(矿源岩)、岩性(建造)、岩浆岩、矿物标型、金的成色、热液蚀变、构造、地球化学和植物等9个方面.在漫长的地质历史过程中,影响金矿成矿的因素复杂多样,应用上述标志时,应根据地质条件和矿床类型全面考虑.
Exploration Guides for primary gold deposits may be sumarized as: source bed (source rock);petrographical formation; magmatite; typomorphic mineral; relative purity; hydrothermal alteration;geological structure; geochemistry, and indicator geobotany. Each exploration guide has its representativeness and limitation to a certain extent. During such a long geological history the minerogenesisof a primary gold deposit might be effected upon by many different factors. In using these guide forexploration, the geological conditions and types of the ore deposits should be taken into consideration in an all-round way.
