文摘

Zinc ore and hematite breccias have distinct densities and magnetic susceptibilities. Uranium enrichment of zinc ore allows for gamma-ray survey integration in exploration. Gravity methods are the most effective geophysical tool for zinc exploration. Combining magnetic, gravity and gamma-ray surveys may be needed to identify zinc ore.
