Abstract A statistical analysis of magnetic characteristics of genetically different granites shows that different types of granites composed of different mantle source materials have different magnetic characteristics: the more the deep source materials in the granite, the stronger the magnetism. The judgment of the genetic type of the granite on the basis of the intensity of magnetism is of important geological significance in geological interpretation of the magnetic surveying data obtained from the southeast coastal area of China as well as in the related geological researches and ore-prospecting work.
