摘要
成矿多样性是成矿事件的根本表现 ,它不仅表现为一个矿床在成因、形态、尺度、矿石类型、矿石组合、有利及不利组分上的多样性 ,还表现在矿床、矿田、矿带、成矿省、成矿区域及成矿时期上的多样性 .成矿多样性在成矿物质基础上受矿源地质异常控制 ,在成矿物质运移上受运矿地质异常控制 ,在聚矿作用上受赋存环境地质异常控制 ,在成矿后的变化上受保矿与毁矿地质异常控制 .因此 ,可以通过地质异常背景的研究来揭示成矿多样性的具体特征 .矿床谱系在时间、空间及成因上与成矿多样性密切相关 ,它在评价与预测新类型矿床中起着极其重要的作用 .因此 ,了解成矿多样性与矿床谱系 ,对研究超大型矿床、成矿流体、区域矿化以及揭示成矿规律 ,具有十分重要的指导意义 .
Diversity of mineralization is an essential phenomenon in ore-forming process. It is represented not only in genesis, morphology, attitude, dimensions, ore types, ore combination, useful and damaging elements within one deposit, but also in ore deposits, ore fields, ore belts, ore provinces, mineralized district and metallogenic epoch. It is subject to geo-anomalies of ore source in the origin of ore materials, to geo-anomalies of ore fluid in the carrier of ore medium, to geo-anomalies of ore transformation in energy, to geo-anomalies of reservoir environment in ore accumulation, and to geo-anomalies of preservation or destruction in post-metallogenic diversification. Therefore, the characteristics and attribution of diversity of mineralization may be determined by the geo-anomaly background. The spectrum of ore deposits is related genetically with the diversity of mineralization, which may play an important role in appraising and forecasting new types of mineral deposits. So the research of diversity of mineralization and its spectrum of ore deposits is of great significance in discovering regional rules of mineralization as well as research of supper-large ore deposits, ore fluid and regional mineralization on a large scale.
