    The re-application of placer mineral survey data in mineral resources investigation——A case study of the Yuxian area in Hebei

    • Abstract:Natural placer mineral survey is one of the important methods of mineral investigation. It is a realistic problem how to fully extract mineralization information from placer mineral, give play to its role in mineral resources investigation. Denudation and re-deposition of heavy minerals is an important process in forming placer mineral. By giving adequate cansideration ot the natural precipitation catchment way, it is an objective explanation that the boundary of the catchment basin is the scope of the placer mineral anomalies. The research on the model of region mineralization, geochemistry and heavy mineral concentrate data are important supplements to the application of the placer mineral suruey data. This article analyses the placer muineral survey data of the Yuxian area (1:200,000) and makes some studies and attempts in respect to understanding and evaluating anomalies, using the investigation method, applying the software platform, looking for unknown mineral resources in areas where the level of mineral exploration and exploitation is relatively high.
