• Choosing the atomic absorption spectrometry as a basic analytic method and icp / ms as a contrast method and using the sequential selective extraction schedule , the characteristics of weak geochemical signals from deeply concealed deposits were studied in loess covered jiaolongzhang polymetallic deposit and zhangquanzhuang gold deposit
  本文采用原子吸收法作为基本分析方法，并以icp ms为比较方法，通过选择性循序提取试验，研究了甘肃蛟龙掌多金属矿和河北张全庄金矿黄土覆盖条件下，地表黄土中地球化学弱信息特征。
