Recognizing OIB and MORB in accretionary complexes: A new approach based on ocean plate stratigraphy, petrology and geochemistry

“…5). The age of the terrigenous succession, which is dominated by siliceous mudstone and land-derived siliciclastic sandstone overlying the cherts (OPS Type 2), is earliest Late Permian (Sano et al, 1987). The two successions, which probably formed at seamount base and on oceanic floor (pelagic facies), represent pelagic-hemipelagic-trench OPS (Type 1).…”
