Figure F4. (A) Primitive mantle-normalized trace element concentration diagrams and (B) C1 chondrite-normalized REE abundances patterns for basement rocks from Site U1414 (Hole U1414A). Data for primitive mantle and C1 chondrite are from Sun and McDonough (1989). Data for normal mid-ocean-ridge basalt (N-MORB), enriched mid-ocean-ridge basalt (E-MORB), and ocean island basalt (OIB) are from Niu and O’Hara (2003).
