Based　on　analyses　of　SIMS　U-Pb　ages　and　Hf　and　0　isotopes　of　magmatic　zircons　from　various　rocks　in　the　Zijinshan　area,　Fujian　Province,　the　magmatic　evolution　series,　source　characteristics,　and　crust-mantle　interaction　of　these　rocks　have　been　discussed　in　this　paper.　Results　show　that　there　are　at　least　five　epochs　of　intrusions,　including　Middle　Proterozoic,　Simian,　late　Early　Paleozoic,　Late　Trias　sic,　and　Late　Jurassic,　with　zircon　U-Pb　ages　varying　from　151　Ma　to　1514　Ma.　The　zircon　Hf　two-stage　depleted　mantle　model　ages(tDM2),　which　are　Early　Proterozoic　and　zircon　ϵHf(t)　values,　which　are　plotted　the　line　of　mafic　crustal　evolution　indicate　that　the　Early　Proterozoic　crust　could　be　the　main　source　of　intrusive　rocks　with　ages　varying　from　Middle　Proterozoic　to　Late　Jurassic　in　the　study　area.　ϵHf(t)　and　δ18O　values　of　zircons　show　the　Middle　Proterozoic　and　Sinian　magmatic　rocks　were　sourced　from　both　mantle　and　Early　Proterozoic　crust　;　while　the　Early　Paleozoic,　Late　Triassic　and　Late　Jurassic　magmatic　rocks　were　mainly　sourced　from　the　crust,　with　more　influence　of　depleted　mantle　material　to　the　Late　Jurassic　magmatic　rocks.
