Figure F8. X-ray diffractograms for (A) bulk sediment, Section 198-1210B-6H-1. Curves are shown for three preparation treatments: acid-leached only (red), glycolated (blue), and heated (green). Peaks for clay minerals identified from diffractograms are superimposed on the data. (Continued on next page.)
