Geosphere, October 2011, v. 7, p. 1102-1133, doi:10.1130/GES00669.1, Supplemental Figure File - PDF file of four figures. The figures include a ternary AFM plot and an orthogonal plot of agpaitic index versus alumina saturation index for samples of the Ancestral Cascades arc as well as average chondrite-normalized REE patterns for each volcanic rock age group and for 25-18 and 17-8 Ma plutonic rocks of the Ancestral Cascades arc.
