摘　　要：运用地球化学块体理论,在福建省1∶20万区域化探数据基础上,利用10km×10km窗口数据,圈定了紫金山矿集区金地球化学异常,依据大型矿床地球化学定量评价模型和方法计算出金的找矿潜力。本文尝试在该块体中通过提高分级值,对紫金山矿集区区域地球化学异常进行了圈定并勾绘出内部结构的谱系树图。分析了金地球化学块体各级含量水平所对应的面积、可供金属量、浓集度等参数特征。探索金元素地球化学块体的内部结构,揭示金在地球化学块体中逐步浓集的轨迹,最终指出找矿方向。Geochemical blocks and their-inner structure of Fujian Province were analyzed in this paper. Geochemical blocks were delineated by 10km×10km window data based on 1：200000 regional geochemical surveys. Potential reserves of gold was estimated based on geochemical quantitative assessment model. The internal structure of the geochemical blocks for certain element may reveal its ways of concentration and formation in the regional geochemical anomalies. Predictive evaluation was carried out for major gold regional geochemical anomalies,which might be the potential areas for follow-up exploration.
