摘要
本文应用灰色系统的关联度分析，对全国花岗岩型金矿成矿有关的７８个地质变量（因素），在１６０８个预测单元中，计算出每个单元与胶东金矿之间的关联度，通过趋势分析绘制了残差值的等值图，圈定了异常，指出了全国金矿床的找矿方向。
This paper calculates the relational grade between each unit and gold deposit inJiaodong among the l 608 prediction units of the national granite-type gold deposits concerning78 geologic variants(factors)with the relational grade analysis of the grey system. The isopleth ofthe residual value is drawn through trend analysis and anomaly is outlined.The way for oreprospecting of national gold deposits is pointed out.
