According to the study of the relationship between rock-forming elements and geophysical properties (such as the density, susceptibility, resistivity and chargeability) of sedimentary rocks, volcanic rocks,intrusive rocks and metamorphic rocks,it is known that the correlativity between petrophysical and petrochemical data varies in accordance with petrogenetic factors and parameters.Geophysical prospecting and geochemical prospecting describe a geological body in different directions.Prospecting methods can be combined properly to make geological survey informative.
