Figure F3 (continued). B-D. Compositional map: (B) Mg, (C) Ca, and (D) Al. Ol = olivine, Plag = plagioclase, CPlag = calcic plagioclase, LCPlag = less calcic plagioclase, Opx = orthopyroxene, Amp = amphibole. Scale bars = 200 µm. Calcic plagioclase and amphibole are not distinguished in (C) due to their similar Ca contents. Note the calcic and less-calcic plagioclase grains within the vein and their irregular-shaped boundary (C) and (D).
