Geochemical anomalies of gold and tungsten in Ningdun area are dominated by the element association of

AuAsWBi. These anomalies are well coincident with the structural rifting belt. They are  characterized by

high intensity, extensiveness, and remarkable zoning, and are evidently controlled by NEtrending faults. Both

secondary and primary anomalies exist in the area, as revealed by highintensity sampling in stream sediments,

soil and rock profile survey and geological investigation across the profile. The inspection method has been proved

to be effective. Anomalies occur in places of numerous folds and rifts, where there exist granodiorite porphyries

with such highbackground elements as Au and W, abundant material sources and heat as well as excellent geological

settings for mineralization. There are four mineralized bodies of gold, but they are not consistent with the

anomalies there in intensity and dimension. In addition, oreforming elements of Au, W and Mo are as high as

associated elements of As and Bi in content in mineralized altered rocks of the rifting belt. All these features

suggest good prospects in search for Au, W and Mo in the area.
