Fig. 6. Compositional fields for olivine in the Rio Boba mafic-ultramafic plutonic sequence. Fields of olivine compositions: Omán mantle peridotites (Gelbert-Gallard, 2002; Bodinier and Godard, 2007), Cabo Ortegal mantle peridotites (Santos et al., 2002), SSZ mantle pyroxenites from Solomon Islands (Berly et al., 2006), and lower crustal gabbronorites in Talkeetna arc (Green et al., 2006). Grey fields: olivine in Puerto Plata and La Cuaba harzburgites (Escuder-Viruete et al., 2014; Escuder-Viruete and Castillo-Carrión, 2016). Arrows reflect olivine differentiation trends in the Caribbean mantle and crustal rocks.
