| Three-dimensional Modeling and Comprehensive Metallogenic Prediction of the Zaozigou Gold Deposit, Gansu Province |
| The Zaozigou gold deposit in the west Qinling metallogenic belt of Gansu Province is a typical representative of large-sized tectonic-altered lithologic gold deposit with high degree of studies. To investigate the prospecting direction and metallogenic potential in the depth of the Zaozigou gold deposit, the authors adopted the three-dimensional geological modeling method and the method of extracting favorable information for mineralization to carry out the three-dimensional modeling and comprehensive metallogenic prediction based on the ore-prospecting geological model. The results show that the Zaozigou gold deposit is suitable for the utilization of comprehensive geological prospecting model of ore-controlling fault + favorable rock mass + favorable wall rock alteration + equidistant ore-controlling. The results of quantitative analysis and extraction of geological anomaly variables are well confirmed in geological understanding. The comprehensive mineralization prediction results show that the enrichment of this deposit was obviously attributed to the superimposed mineralization controlled by multi-stage structure, and the main orebodies such as Au1, Au9, Au30 and M16 have good prospecting potential in the depth. |
