矿床品位 -吨位模型研究属于学科前沿领域 ,它是系统勘查理论的重要组成部分 .依据 1997年全国矿产储量数据库资料 ,对全国 6 80个岩金矿床建立了地质模型、品位模型、吨位模型、吨 -品位联合模型 ,以及中国石英脉型金矿床吨位序列模型 .模型类型包括频率直方图、累积频率分布图及双对数坐标表示的理论分布模型 .分别总结了我国岩金矿床的品位及吨位分布的典型数学地质特征 ,并探讨了吨位序列模型在资源预测评价中的意义和作用 .
According to the data of 1997 National Mineral Reserve Database, the geological model, grade model, tonnage model, tonnage model and so on are established for the country’s 68 rock gold deposits. - grade combination model and the tonnage sequence model of quartz vein type gold deposit in China.The model types include the frequency histogram, the cumulative frequency distribution and the theoretical model of double logarithmic coordinates.The paper summarizes the grade and tonnage distribution of the gold-gold deposits in China , And discusses the significance and role of tonnage sequence model in resource prediction and evaluation.
