    河南栾川县马丢大型萤石矿矿床地质特征及其找矿潜力预测

    Geological characteristics and prospecting potential of the Madiu large–scale fluorite deposit in Luanchuan County, Henan Province

      摘要
    • 摘要:
      研究目的 萤石矿是现代工业必须的重要矿产资源，河南省把萤石矿的找矿列为非金属矿产的重中之重。近年来，河南省多个地勘单位均在栾川县合峪地区从事萤石矿找矿工作，马丢萤石矿是第一个探明的大型矿床，估算萤石矿矿石量884万t、CaF2矿物量476万t，CaF2平均品位53.83%，矿体沿走向东西两端均未封闭。总结马丢萤石矿矿床地质特征对指导该区找矿具有重要意义。
      研究方法 通过近5年来对马丢萤石矿的普查—详查工作，对矿床成矿地质条件、矿床地质特征、质量特征、找矿标志等进行系统总结。
      研究结果 马丢萤石矿床目前是河南省及其周边省份资源量规模最大的萤石单矿体。矿脉数量多，规模大小不一，具有沿倾向等间距分布，沿走向近平行展布的特征，在其周边还分散着众多的萤石矿体。
      结论 马丢萤石矿成矿与花岗岩体和北西向构造有关，矿床类型为硅酸盐岩石中的裂隙充填中—低温脉状矿床。

       

      Abstract:
      This paper is the result of mineral exploration engineering.
      Objective Fluorite is an important mineral resource in modern industries, and it is listed as the top priority of nonmetallic mineral prospecting in Henan Province. In recent years, several geological prospecting units in Henan Province have been engaged in prospecting fluorite in the Heyu area of Luanchuan County, and the Madiu fluorite deposit is the first proven large deposit, with an estimated amount of 8.84 million tons of fluorite ore and 4.76 million tons of CaF2 mineral. The average grade of CaF2 is 53.83%. The east–west ends of the ore body are not closed along the strike. Therefore, summarizing the geological characteristics is of great significance for guiding the prospecting activities in this area.
      Methods Based on the general and detailed investigation of the Madiu fluorite deposit in the last five years, the metallogenic geological conditions, geological characteristics, quality characteristics, and prospecting indicators are systematically summarized.
      Results The Madiu fluorite deposit is the largest single fluorite ore body in Henan and its surrounding provinces. There are many ore veins of different sizes, which are equal spaced along the trend and are nearly parallel along the strike. There are also many fluorite ore bodies scattered around.
      Conclusions The Madiu fluorite mineralization is related to granites and NW–trending structures, and the deposit type is medium–low temperature vein deposit with fissure filling in silicate rock.
