Figure F3. Examples of XRD analyses for Site 1226. Samples from (A) a diatom-rich nannofossil ooze layer, (B) a nannofossil-rich diatom ooze layer, (C) a yellow dolomite nodule, (D) a dark speck in diatom nannofossil ooze, (E) a brown chert layer, and (F) a green porcelanite layer. A = opal-A, C = calcite, B = barite, P = pyrite, D = dolomite, Q = quartz, T = trydimite, Cr = crystobalite, V = vermiculite, K = kaolinite, He = hematite.
