Figure 3. N-MORB normalized multi-element patterns for the (a) MORB-, (b) OIB- and (c) SSZ-type basaltic lavas from the Tethyan suture zone in western Turkey. Average E-MORB and OIB compositions are shown by grey and dark heavy lines, respectively. E-MORB, OIB compositions and N-MORB normalizing values are from Sun & McDonough (1989).
