摘要
中国砂金探采粒度存在一定的差异，这种粒度特征的变化是造成砂金勘探地质品位贫化的内在因素。认真研究砂金粒度特征及其对勘探地质品位的影响，是进行砂金勘探时降低勘探地质品位贫化的重要途径，尤其是在砂金“回头看”
The grain size of placer gold in various prospecting target in China are different.The characteristics of grain size have become internal factor of dilution of geological grade of placer gold prospecting.Seriously studying such characteristics and their influence on geological grade is an important approach to the lowering of grade dilution of placer gold prospecting.
