Abstract

Geochemical data is essential for mineral exploration, and one of the main challenges is how to identify the anomaly that was related to the formation or locations of mineral deposits. Many techniques have been developed to identify geochemical anomalies in the past years, but most of these techniques are designed for univariate data. To identify geochemical anomalies from multivariate geochemical data and to get gold deposits related information, logistic regression method is used to analyze geochemical data (sixteen hydrothermal/epithermal elements are included) of this study area. The results demonstrate that the developed logistic regression model is effective for geochemical anomalies identification and gold prediction, because the model can not only identify the geochemical anomalies where there are known gold deposits, but also identify other strong geochemical anomalies where there is no known deposit. Therefore, the logistic regression method is recommended to be used to geochemical anomalies identification and mineral prediction.
- logistic regression,
- geochemical anomaly,
- gold deposit
