萤石矿自然重砂矿物组合规律及其找矿意义

    Combination features and exploration significance of natural heavy minerals from fluorite deposits

    • 摘要: 为探究不同类型的萤石矿所反映的自然重砂矿物组合所携带的对各类型萤石矿的指示特征,统计了浙江、湖南、湖北、青海、广西、福建、安徽、新疆、甘肃、河北共计10个地区23个典型萤石矿床的自然重砂矿物报出情况,计算各重砂矿物报出率,分析得出热液型矿、后期热液型及热液充填型3种类型萤石矿床各自对应的自然重砂矿物组合和标型矿物组合。结果显示,各类型矿床自然重砂矿物组合既有相同之处也有显示各自的特点。因此,按照矿床类型建立的自然重砂矿物组合及其含量变化,对于新一轮的矿产资源勘查具有重要的意义。

       

      Abstract: To investigate different types of natural fluorite ore deposits reflected by heavy minerals from various types of fluorite ore deposits, the authors summed up the statistics of the frequencies of occurrence of heavy minerals in 23 typical fluorite deposits in Zhejiang, Hunan, Hubei, Qinghai, Gguangxi, Fujian, Anhui, Xinjiang, Gansu and Hebei, analyzed characteristics of late hydrothermal fluorite ore deposits, hydrothermal type fluorite ore deposits and hydrothermal filling type fluorite ore deposits. It is shown that three types of ore deposits have their respective natural heavy mineral assemblages and typomorphic mineral combinations. The results achieved by the authors show that the establishment of natural heavy mineral assemblages based on ore deposit types are of important significance for the new-round mineral exploration.
