Ophiolites - Volcano World - Oregon State University
Ophiolites are pieces of oceanic plate that have been thrusted (obducted) onto the edge of continental plates . They provide models for processes at mid-ocean ridges. Ophiolites are an assemblage of mafic and ultramafic lavas and hypabyssal rocks found in association with sedimentary rocks like greywackes and cherts. volcano.oregonstate.edu
