地质

However, the mathematical study of the geology of this area is still lacking. On the basis of geological field survey, we have made systematic sampling and geochemical analyses of the rocks, and systematically studied the relationship between the Cu-Ni variable and the rock-forming element variables by the method of multi-variate...
