According to the soil geochemical survey result of 20 km2range in Jinshan mineralization zone��u- sing cluster and factor analyses��the authors concluded that Au has better positive relevance with Ag��As and Sb than other elements�� These elements can be as the good indicators for gold mineralization prospecting�� By measur- ing the background value and anomaly threshold of each element��there are 9 anomalies of Au and 35 anomalies of other elements delineated�� The gold ore bodies in sulfurous altered rock type and quartz vein type are mainly devel- oped within the zone�� North-west fracture is the most important ore-controlling structure�� Integrating the geological conditions with the abnormal characteristics of elements��we extracted three prospecting targets with �� level and two target sections with �� level��and with the surface trenching engineering work in �� level target sections��14 ore bodies were delineated��
