The authors hold that the joint actions of numerous factors such as the upper mantle uplifted zone ( the mantle thinned zone of lithosphere ), the upper mantle anomalous area ( relatively low - velocity area ), the uplifted zone of intracrustal high - conductivity layer, the deep fault ( shear zone of lithosphere ), the margin of the crust - upper mantle uneven masses, the basement uplifted area reflected by gravity high, the magmatic belt and tectonic intersection reflected by skipped magnetic field, control the distribution of auriferous skarn deposits and copper ( associated with gold ) skarn deposits
