EVALUATION OF REGIONAL GEOCHEMICAL ANOMALIES WITH BIG-AREA,LOW-CONCENTRATION ZONING AS EXEMPLIFIED BY THE DISCOVERY OF DULENGGOU Cu-Co DEPOSIT |
| |
Abstract: | Based on the geological background of stream sediment anomalies, geological features of ore deposits and evaluation of different kinds of anomalies, this paper introduced the discovery process of the Dulanggou deposit. Aiming at the characteristics of stream sediment anomalies in the Dulanggou Cu Co deposit, the authors put the focus on the importance of evaluation of big area, low concentration zoning anomalies, and propose a new method and new thinking path for such anomalies during regional geochemical exploration. |

Keywords: | regional geochemistry concentration zoning anomaly evaluation Dulenggou Cu-Co deposit |
