Abstract: According to the 1:50000 scale high precision aeromagnetic anomaly survey and geological features for area selection, combined with the 1:20000 integrated geophysical-geochemical exploration and verification technology, the skarn-type Zn polymetallic deposit is found in the aeromagnetic anomaly area of Yichun, Xiaoxinganling Mountains, reflecting the applicability of aeromagnetic survey technology in such prospecting. The verification results indicate that the aeromagnetic anomaly area in the contact between the Lower Cambrian marble strata and intrusions is an important target for skarn type polymetallic deposits. The host area shows the geophysical characteristics of low resistivity and high polarization. Pedogeochemically, the element association anomaly of Ag, As, Sb, Mo, W, Bi, Pb, Cu and Zn occurs in the contact area, with well coincidence. The high Sb anomaly value appears in inner zone, while Zn commonly in the middle zone.
