     Granodiorite in Guangxi Fuzichong lead-zinc deposit are closely related to mineralization in spatial distribution, while the ore-bodies are mainly occurred in skarn zone between sedimentary rocks and granodior- ite. LA-ICP-MS zircons U-Pb dating of granodiorite and pegmatite in Fuzichong deposit are yielded average ages of- 228 Ma and - 248 Ma respectively, ha space, only the distribution ofpegmatite veins near the gran- odiorite, granodiorite have left in the pegmatite. Two samples of zircon REE characteristics are very similar, single zircon isotopic ages of both are basically the same, and concordance with the time of Qingzhou- Fang cheng trough starting close and beginning collision of Yangtze and Cathysia plate, which indicated that Fuzi- chong deposit was formed by magma intrusion in old stratum along Cenxi - Bobai deep fault in Hercynian - earlier Indosinian.
