Permian　marine　strata　have　gradually　become　a　research　focus　in　the　world.　The　marine　strata　of　the　Late　Permian　Dalong　Formation　(P3d)　in　the　Fenghai　area,　Fujian　Province,　have　become　more　and　more　important　as　their　geochemical　characteristics　record　important　geological　information　and　are　a　good　indicator　for　recovering　and　reconstructing　the　paleo-sedimentary　environments　and　tectonic　attributes.　The　major　elements,　trace　elements　and　rare　earth　elements　were　analyzed　by　XRF　and　ICP-MS,　respectively.　Based　on　the　results　of　detailed　field　geological　surveys,　profile　measurements　as　well　as　typical　sample　collection,　the　tectonic　setting　and　provenance　of　Permian　marine　mudstone　were　comprehensively　discussed.　The　results　showed　that　the　Dalong　Formation　(P3d)　was　deposited　in　an　active　continental　margin　tectonic　environment　as　revealed　by　the　relation　between　Fe2O3　+　MgO　and　TiO2　and　Al2O3/SiO2.　The　fingerprint　characteristics　of　Mn,　Fe,　Co,　Ni　and　REE　and　the　ratio　of　U/Th,　V/Cr,　Sr/Ba,　(La/Yb)N　and　V/(V　+　Ni)　indicated　that　the　sedimentary　provenance　was　mainly　derived　from　potassium　feldspar,　followed　by　muscovite.　Sedimentary　water　bodies　showed　a　gradually　decreasing　depositional　rate　trend,　water　depth　gradually　shallowing　and　paleo-salinity　and　productivity　gradually　increasing.　Moreover,　since　transient　delamination　occurred　during　sedimentary　processes,　sedimentary　water　bodies　showed　obvious　neritic　characteristics.　It　was　consistent　with　the　results　revealed　by　lithological　and　geochemical　characteristics.　Calcareous　mudstone　and　siltstone　transitioned　into　fine　sandstone　from　bottom　to　top,　indicating　paleo-water　bodies　became　shallow.　The　research　results　provided　good　reference　and　guidance　for　understanding　Permian　paleo-sedimentary　environments　and　tectonic　attributes　of　the　Yong’an　area,　Fujian　Province,　southeastern　China.　©　2019,　The　Author(s).
