宝兴沟金矿床位于大兴安岭北部，是近年来通过土壤地球化学测量查证小比例尺水系沉积物测量异常时发现的金矿床。通过土壤测量，成矿元素地球化学特征显示：Au丰度值高，变异强度大，为主要成矿元素，与As、Sb相关性好， Au元素所形成的异常是金矿找矿的直接标志， As、Sb异常可作为间接找矿标志。通过后期地表槽探工程查证土壤测量所圈定的异常，发现2条金矿化蚀变带，并显示出较好的找矿潜力。土壤测量找矿方法在宝兴沟金矿区得到了较好的应用，也证明了该方法在大兴安岭北部森林沼泽景观区找矿是有效的。
Baoxinggou Gold Deposit is located in the northern Great Khingan Mountains. The deposit is recently discovered when the anomalies of small-scale stream sediment survey were verified by soil geochemical survey. The soil geochemical characteristics show abundance value of Au, the main ore-forming element, is high and the variation strength is great;Au is associated with As and Sb,which can be used as indirect signs of prospecting;anomalies asso-ciated with Au are direct signs of gold prospecting; Through verifying anomalies of soil survey by trenching works, 2 gold mineralization alteration zones are found with good potentials for mineralization. The application of soil survey prospecting method in Baoxinggou Gold District proves effective in the prospecting in forest and swamp landscapes in northern Great Khingan Mountains.
