Correction to: Using the catchment-based fractal model to delineate geochemical anomalies associated with Cu-W polymetallic deposits in the Zhuxi, Jiangxi Province

In this paper, a concentration-area (C-A) fractal method based on catchment basin, rather than regular grid, is performed to identify stream-sediment geochemical anomalies. First, a catchment basin determined by drainage divides is derived from the digital elevation model (DEM) after filling sinks on a GIS platform. Second, the log-log plot of concentration against areas is used to obtain threshold values to separate stream-sediment geochemical anomalies from background. Finally, a comparison between the results generated by C-A fractal model based on irregular catchment basin and regular grid is made. There are some similarities for geochemical anomalies between the regular grid and the catchment-basin models. However, the C-A fractal model based on catchment basin shows an advantage in identifying high-value anomalies, especially for univariate geochemical element, which can be used for field verification. Additionally, Cu mineralization has been found in the three target areas through field verification. This research can provide important information for the prospecting of Cu-W deposits in this region.
