在个旧东部矿区,过去应用原生晕推测成矿母岩——燕山期花岗岩的埋藏深度,由于使用的化探指标系非定量化的,故仅能给出一个误差颇大的深度范围.本文研究了白泥垌矿床内,成矿花岗岩沿三迭系个旧组碳酸盐类岩层层间剥离带的原生晕中,主要成矿和伴生元素Be、Bi、 In Gejiu eastern mining area, the depth of burial depth of the Yanshanian granitoid, the primary parent rock speculated ore-forming parent rock, was used in the past because the geochemical indicators used are not quantitative, so it can only give a deep error range. In the Baijiangyan deposit, the metallogenic granites along the primary sediment of the Triassic Gejiu carbonate strata, the main ore-forming and accompanying elements Be, Bi,
