Abstract: The authors have systematically studied geological and geochemical anomalies obtained by exploration of different scales of the Zimudang gold deposit and have established geochemical exploration models of three different scales for the Zimudang finely disseminated gold deposit, i.e. regional (1:200000), ore field (1:50000) and deposit (1:10000). They are of certain value for the evaluation of 1:200000 regional geochemical anomalies
