Knowledge　of　the　crustal　structure　is　important　for　understanding　the　tectonic　framework　and　geological　evolution　of　southeastern　China　and　adjacent　areas.　In　this　study,　we　integrated　the　datasets　from　the　TAIGER　(TAiwan　Integrated　GEodynamic　Research)　and　ATSEE　(Across　Taiwan　Strait　Explosion　Experiment)　projects　to　resolve　onshore-offshore　deep　crustal　seismic　profiles　from　the　Wuyi-Yunkai　orogen　to　the　Taiwan　orogen　in　southeastern　China.　Three　seismic　profiles　were　resolved,　and　the　longest　profile　was　850　km.　Unlike　2D　and　3D　first　arrival　travel-time　tomography　from　previous　studies,　we　used　both　refracted　and　reflected　phases　(Pg,　Pn,　PcP,　and　PmP)　to　model　the　crustal　structures　and　the　crustal　reflectors.　In　total,　data　from　40　shots,　2　earthquakes,　and　approximately　1,950　stations　were　used;　15,612　arrivals　were　selected　among　three　transects.　Using　these　data,　we　determined　the　complex　crustal　evolution　since　the　Paleozoic　era,　involving　the　closed　Paleozoic　rift　basin　in　central　Fujian,　the　Cenozoic　extension　due　to　the　South　China　Sea　opening　beneath　the　coastline　of　southern　Fujian,　and　the　on-going　collision　of　the　Taiwan　orogen.　The　shape　of　the　Moho,　which　also　reflects　the　crustal　evolution,　can　be　summarized　as　follows:　~　30　km　deep　to　the　west　of　Fujian,　deepening　toward　central　Fujian　(~　35　km),　becoming　shallower　toward　the　Taiwan　Strait　(~　28　km),　deepening　again　toward　the　mountain　belt　of　Taiwan　(~　42　km),　and　becoming　shallower　toward　the　Pacific　Ocean　(~　10　km).　©　2015　Elsevier　B.V.
