The　detrital　zircons　have　become　one　of　the　major　tools　for　the　study　of　regional　geological　evolution.　In　this　paper,　the　authors　conducted　the　LA-MC-ICP-MS　U-Pb　dating　and　Hf　isotopic　analysis　for　the　detrital　zircons　from　the　conglomerate-bearing　quartz　sandstone　occurring　in　the　basal　part　of　the　Shanghang　basin　in　Cathaysia　Block.　It　is　shown　that　these　detrital　zircons　are　magmatic　in　origin.　The　age　data　obtained　from　these　detrital　zircons　range　from　3　403　Ma　to　328　Ma,　which　document　at　least　10　magmatic　events　in　the　region,　indicating　a　long　and　complex　geological　evolution.　Similar　to　ages　of　the　detrital　and　captured　zircons　in　other　regions　of　the　Cathaysia　Block,　the　ages　of　the　detrital　zircons　from　the　Shanghang　basin　reveal　the　global　events,　such　as　the　Neoarchean-Paleoproterozoic　crustal　growth　event,　the　assembly　and　breakup　of　supercontinents　Columbia　and　Rodinia,　and　the　assembly　of　Gondwana　as　well　as　regional　events,　such　as　the　Early　Paleozoic　intense　intraplate　orogeny　(Wuyi-Yunkai　orogeny)　with　the　characteristics　of　the　Cathaysia　Block.　The　most　prominent　450　Ma　peak　indicates　that　the　Caledonian　orogeny　(locally　called　Wuyi-Yunkai　orogeny　or　Kwangsian　orogeny)　is　the　most　important　event　in　the　region.　The　in　situ　Hf　isotope　compositions　give　a　large　range　of　εHf(t)　values　(-27.2　to　19.8)　with　two-stage　model　ages　(tDM2)　of　1　124~3　979　Ma　(peak　of　1　800~　1　900　Ma).　The　Hf　data　suggest　that　the　early　magmatism　was　mainly　associated　with　the　large　scale　crustal　growth,　while　the　late　one　was　related　to　the　reworking　of　the　early　crust,　involving　the　recycling　of　older　crustal　components　with　less　juvenile　crustal　growth.　©　2016,　Science　Press.　All　right　reserved.
