| 摘 要： | 通过对东南沿海不同成因类型的花岗岩磁性特征进行统计分析,表明由于源岩物质的不同,不同成因类型花岗岩的磁性差别很大,深源物质越多,磁性越强,反之则磁性越弱.根据磁性的强弱变化来判断其成因类型,对于东南沿海地区航磁资料的地质解释以及相关的地质研究、指导找矿等都具有重要的地质意义.

| 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. |

| Keywords: | southeast coastal area of China granite type magnetic characteristics mantle material |
