摘要
目前流行的岩金矿床分类方案是依据地表已遭受一定剥蚀的矿床地质特征和成因理论而建立的 ,为了有效地开展隐伏岩金矿体定位预测工作 ,必需重新认识和划分矿床类型 ,弄清哪些特征真正具有可比性。文中分析了现有分类方案中几个亟待解决的问题 ,结合金矿的“特殊性” ,提出应简化矿床类型、将成矿区带作为分类的目标 ,将成矿系统作为分类的基础。
The popular classification schemes of lode gold deposits have been established basically according to the geological characteristics and genetic theories of those partly denudated lode gold deposits. In order to proceed effectively with the positioning prognosis of concealed lode gold deposits, it is necessary to re understand and re classify the types of ore deposits and to reveal those real comparable properties among ore deposits. The paper analyzes several urgently settled issues in relation to the existing classification schemes of lode gold deposits. In combination with the peculiarities of gold deposits, the paper suggests that the types of ore deposits should be simplified, the metallogenic zones and belts should be considered as the objects of classification and the metallogenic system should be taken as the basis for classification.
