Abstract: Gold deposits are controlled by lithology, structure and alteration. The alteration may result in radioactivity difference between ore bearing structure zone and the wall rock. Therefore the gammaray spectrometry may be used in gold deposit exploration. Gammaray spectrometry survey made in the outer region Liushuhe area of Wulaga gold mine in Heilongjiang Province is taken as an example in which the ore bearing structure zone is revealed and the characteristic on the mineralization liquid at middle to low temperature is indicated. Potassium (K) and the total channels appear high anomalies on the mineralization zone while uranium (U) shows low anomalies. The overall results prove that spectrometry is effective in gold exploration in the study area. It is necessary to point out that gammaray spectrometry may be characterized differently over different exploration area and different deposit types.

Key words: gold deposit exploration, gammaray spectrometry, Liushuhe area
