This image above is from the Xigaze forearc basin in Tibet and shows a textbook example of filling an ocean basin (the rocks are tilted about 45 degrees). On the far right is a dark greenish rock called an ophiolite (ocean crust), which is overlain by a short section of red radiolarian chert, which is then overlain by a very thick section of brown-yellow turbidites.
