文摘After studying systematically Petrology, Mineralogy, Petrochemistry, REE geochemistry and strontium, sulphur, lead isotope of the alkali-rich granite prophyry distribuled extensively the Yangtze platfrom western margin’s alkali-rich granite porphyry we point out that the alkali-rich granite porphyry have the properties of new intrusive ages, Range of the isotope age is form 36 Ma to 51 Ma, they belong to the Himalaya date, Main mineral componets of the alkali-rich granite porphyry consist of k-fcldspar(35~45x), quartz(36x±)plagioclase(15x±)and biotitc(10x±).
