Figure F3. X-ray diffractograms for standard mineral mixtures analyzed as oriented clay aggregates (<2 µm). Note the actual weight percentages of each mineral within each mixture. Peaks used for calculation of SVD (singular value decomposition) normalization factors are smectite (001), illite (001), chlorite (002), and quartz (100).
