Appendices 1-10. X-Ray Diffractograms of powdered samples from 1) A depositional unit; 2, 3) B depositional unit; 4) C depositional unit; 5, 6) D depositional unit; 7) E depositional unit; 8, 9) F depositional unit; 10) G depositional unit. Peak positions that were used for mineralogical identification are marked by dashed lines. Spacing (for Cu-Ká given in angstroms) is given above the dashed lines. 1-CH-93-22-unit 18) peaks near 18.4 Å and peak near 7.1 probably indicate the d (001) of 2:1 phyllosilicate smectite and 1:1 phyllosilicate kaolinite, respectively. Other peaks in the diffractogram correspond to other d (hkl) indices for smectite and kaolinite not discussed here; 2-CH-93-28-unit 24) peak near 15.9 Å probably indicate the d (001) of 2:1 phyllosilicate smectite. Peaks near 3.1, 3.2 and 3.7 probably indicate d (001, 002) of plagioclase feldspar albite. Other peaks in the diffractogram correspond to other d (hkl) indices for smectite and albite not discussed here; 3-CH-89-24-unit 18) peaks near 3.3 and 9.3 and 7.2 and 3.5 Å probably indicate the d (001, 002) of the 2:1 interstratified clay mineral Illite-smectite and Kaolinite-smectite, respectively. Other peaks in the diffractogram correspond to other d (hkl) indices for illite-smectite and kaolinite-smectite not discussed here; 4-CH-79-65-unit 20) peak near 15.7 Å probably indicate d (001) of 2:1 phyllosilicate smectite. Peaks near 3.1 and 3.2 Å probably indicate d (001, 002) of plagioclase feldspar anorthite. Other peaks in the diffractogram correspond to other d (hkl) indices for smectite and anorthite not discussed here; 5-CH-93-4-unit 4). Peaks near 14.4 and 7.1 Å probably indicate d (001) of 2:1 phyllosilicate smectite and 1:1 phyllosilicate kaolinite, respectively. Other peaks in the diffractogram correspond to other d (hkl) indices for smectite and kaolinite not discussed here; 6-CH-79-67-unit 24) peaks near 15.3 and 2.86 and 6.45 probably indicate the d (001) and d (001, 002) 2:1 phyllosilicate smectite and tectosilicate mesolite, respectively. Other peaks in the diffractogram correspond to other d (hkl) indices for smectite and mesolite not discussed here; 7-CH-93-26-unit 22). Peaks near 16.8 and 7.2 and 3.5 Å probably indicate d (001) of 2:1 phyllosilicate smectite and d (001, 002) of the 2:1 interstratified clay mineral Kaolinite-smectite, respectively. Other peaks in the diffractogram correspond to other d (hkl) indices for smectite and kaolinite-smectite not discussed here; 8-CH-89-1-unit 1) peaks near 7.1 Å probably indicate d (001) of 1:1 phyllosilicate kaolinite. Other peaks in the diffractogram correspond to other d (hkl) indices for kaolinite not discussed here; 9-CH-89-23-unit 17) peaks near 16 and 2.7 Å probably indicate d (001) of 2:1 phyllosilicate smectite and iron carbonate siderite, respectively. Other peaks in the diffractogram correspond to other d (hkl) indices for smectite and siderite not discussed here; 10-CH-89-13-unit 12) peak near 15.7 a d 7.1 Å probably indicate d (001) of 2:1 phyllosilicate smectite and 1:1 phyllosilicate kaolinite, respectively. Other peaks in the diffractogram correspond to other d (hkl) indices for smectite and kaolinite not discussed here.
