The　Jining　Cenozoic　basalt　province,　located　at　the　northern　margin　of　the　North　China　Craton,　is　one　of　the　major　Cenozoic　basaltic　provinces　in　northern　China　and　Mongolia.　In　order　to　constrain　the　petrogenesis　of　the　lining　basalts　and　its　implications　for　the　geodynamic　evolution　of　the　region,　four　basalt　sections　in　Jining　province,　the　Baiyinxiang,　Hanqingba,　Xin＇anzhan,　and　Chahanmiao　sections,　were　analyzed　for　Sr-Nd-Pb-Hf　isotopic　compositions.　These　basalts　are　predominantly　composed　of　alkaline　basalts　and　tholeiites.　The　tholeiites　are　overlain　by　the　alkaline　basalts　in　all　but　the　Chahanmiao　section.　In　general,　the　Jining　basalts　are　similar　to　oceanic　island　basalts　in　terms　of　their　incompatible　element　patterns.　The　epsilon(Hf)　and　epsilon(Nd)　values　of　the　Jining　basalts　range　from　+2.5　to　+9.1　and　-3.6　to　+4.7,　respectively.　They　display　an　epsilon(Nd)-epsilon(Hf)　trend　nearly　parallel　to,　but　above　the　mantle-array　defined　by　oceanic　basalts.　Their　Sr-87/Sr-86　ratios　vary　from　0.7036　to　0.7054,　Pb-206/Pb-204　isotopic　ratios　vary　from　16.9　to　18.0,　Pb-207/Pb-204　varies　from　15.3　to　15.5,　and　Pb-208/Pb-204　varies　from　37.1　to　38.1.　These　data　suggest　the　mixing　of　an　isotopically　depleted　(i.e.,　MORB-like)　mantle　component　and　an　enriched　(i.e.,　EMI-like)　component.　Our　data,　in　combination　with　studies　of　mantle　xenoliths　in　the　region,　suggest　that　the　subcontinental　lithospheric　mantle　may　not　have　made　a　significant　contribution　to　the　EMI　component　observed　in　the　Jining　basalts.　The　deviation　of　the　epsilon(Hf)-epsilon(Nd)　trend　from　the　mantle　array　may　reflect　the　involvement　of　ancient　recycled　continental　crust　in　the　enriched　component.　The　mixing　of　melts　derived　from　(a)　recycled　continental　crust　and　(b)　asthenospheric　mantle　peridotite　may　be　responsible　for　the　geochemical　variations　observed　in　the　magmatic　sequence.　This　is　not　only　so　for　the　Jining　basalts,　but　also　for　the　commonly　occurring　inter-layered　lava　flows　found　between　xenolith-bearing　alkaline　basalts　and　tholeiites　in　the　nearby　Hannuoba　region　and　many　other　basaltic　provinces.　The　upwelling　of　deep　mantle　material　may　have　been　triggered　by　the　western　Pacific　subduction　and　derived　from　above　the　barrier　of　the　stagnant　slab　at　the　similar　to　600-km　mantle　transitional　zone.　The　location　of　the　upwelling　is　likely　in　the　vicinity　of　Jining　and　Hannuoba　as　evidenced　by　the　large　magmatic　volumes　in　the　North　China　Craton　and　the　abundant　mantle　xenoliths　hosted　by　the　Hannuoba　basalts.　(C)　2012　Elsevier　Ltd.　All　rights　reserved.
