Abstract
AbstrcatThe main purpose of geochemical anomaly evaluation is to discriminate ore causing anomaly from the false ones in order to propose the prospective prediction area. Some geochemical characteristics concerned about geochemical anomaly evaluation were discussed including the combination and scale of anomaly elements, geochemical anomaly zoning and supergene geochemical behavior of element, geochemical field and geological background when anomaly occurs, so as to carry out geochemical evaluation from various aspects and find the value of anomalies more completely, scientifically and realistically to achieve better geological result.
