Abstract: The Fozichong lead-zinc ore field is located in Cenxi County, Guangxi Province. From south to north, there occur Guyi, Hesan and Longwan ore deposit. Three periods of granitic rock and two periods of volcanic rock develop in the ore field. Among them, the monzogranitic porphyry played very important role in the mineralization, and has been researched in this paper. It crops out as stock and dyke along NNE-extending to SN-extending faults.To determine the petrogenesis of the monzogranitic porphyry, the metallogenic intrusion and structures of the Fozichong ore field, geologic features, petrography and geochemistry of the monzogranitic porphyry have been involved. The LA-ICP-MS zircon U-Pb dating of monzogranitic porphyry from the three ore deposits reveals that the monzogranitic porphyry in Hesan, Guyi and Longwan simultaneously emplaced at late period of Early Cretaceous, with the duration of (104.2~105.2) Ma. Its geochemical characteristics indicate that the monzogranitic porphyry is high-K, calc-alkaline, metaluminous I-type monzogranitic.The value of εSr(t) varies from 77.98 to 162.66, and that of εNd(t) from -10.4 to -8.3. The depleted mantle model age of monzogranitic porphyry is 1.424~1.672 Ga. The isotope trace suggests that the magma was resulted from the partial melting of Meso-proterozoic meta-igneous rock in middle crust, which implies that the Fozichong ore field has same Precambrian basement as the adjacent Yunkai blok.The Fozichong ore field maybe the part of Yunkai block.The monzogranitic porphyry was induced by the subduction of Pacific Ocean plate to Euro-Asia plate. Besides, Hesan and Longwan ore deposits are skarn-type related to monzogranitic porphyry and carbonate rock. The Guyi deposit belongs to hydrothermal-type related to marble and the‘green rock',a kind of skarn too.The monzogranitic porphyry is not only the ore-forming materials source but also the dynamic source of ore-forming process, composing a typical metallogenic system from skarn-type to hydrothermal-type.

Key words: Fozichong ore field, monzogranitic porphyry, chronology, geochemistry characyeristic, ore-forming process
