In a method for determining metallogenic potential of a porphyry by using trace elements and a B isotope of tourmaline, redox properties of magma is determined with Fe/(Fe+Fe) of tourmaline; then a water content and a content of metal Cu of the magma are determined with contents of HO and Cu in the tourmaline; and a source of the magma is determined with a B isotope of the tourmaline, the water content, oxygen fugacity and metal content and source of the magma are finally determined, and finally, whether the magma has metallogenic potential of a porphyry is comprehensively determined. The present disclosure determines a key control factor of porphyry copper with a mineral of the tourmaline, and overcomes the difficulties in low efficiency, a long period and high cost of a traditional method for determining metallogenic potential.
