The origin and evolution of the Siletz terrane in Oregon, Washington and Vancouver Island
The Siletz terrane, a predominantly mafic accreted oceanic terrane, is located in the Cascadia Forearc region of Oregon, Washington and Vancouver Island. The terrane represents a late Palaeocene – Eocene large igneous province\ud that consists of pillow lavas, massive f... View more
