Location prediction of blind ore-bodies in Shuijingtun Gold Mine, Zhangjiakou, China

Abstract

By analyzing the metallogenic conditions and prospecting marks of F₈ fault belt in Shiujingtun Gold Mine, the geochemical samples were collected along F₈ fault belt and prospecting profile normal to the F₈ fault belt. Gold and its indicator elements were tested with X-ray fluorescence spectrometry and the content distribution diagram of Au, Ag, Hg and As along the F₈ fault belt was performed. The geochemical primary halo model and the Grey system model of F₈ fault belt are established. With these element distribution features and models, the blind ore bodies in the F₈ fault belt were predicted. Engineering prospect shows that the industrial orebodies have been discovered and the prediction results are dependable.
