Abstract The structural characteristics of the regional geochemical field is an important factor in the appraisal of geochemical anomalies. Based on background content of elements and degree of anomaly development in the region, this paper puts forward the simple and clear method for classification of the structures of geochemical fields, divides the regional geochemical field into four basic structural types and, exemplified by Guangdong Province, and tentatively discusses the ore-prospecting significance of the major combinational types. Utilizing the background-anomaly structural classification, we can observe carefully the structural characteristics of regional geochemical field in relation to mineralization. The method is simple and practical, and hence serves as an effective means for rapid delineation of ore perspective areas or ore-prospecting targets.
