Abstract Geochemical anomaly study is one of important links in geochemical exploration and is crucial for discovery of effective anomalies. In this paper, the authors made a study of the 1:50 000 soil geochemical survey data from a certain area in Xinghai County of Qinghai Province, and calculated the anomaly lower thresholds of elements so as to draw the anomaly map of single elements and the composite anomaly map by traditional model. Then the authors built complexity of the elements metrics to draw the complexity map of the elements by assigning an abnormal value to each element, and delineated seven high value areas of complexity of the elements, with which the authors analyzed the degree of erosion and made an evaluation of ore-prospecting potential according to the aspect of element combination by map of the factor score through applying factor analysis. It is found that anomaly area of the factor score map is in good agreement with that of the complexity map of the elements. In addition, it is highly consistent with the known mine. The results show that the method of the metallogenic prediction process is reasonable. In combination with anomaly characteristics and field geological survey, the authors delineated two major target areas for further prospecting.
