Figure F2. X-ray diffractograms for standard mineral mixtures analyzed as random bulk powders. Note the actual weight percentages of each mineral within each mixture. Peaks used for calculation of SVD (singular value decomposition) normalization factors are labeled as follows: CL = composite clay minerals, Q = quartz, P = plagioclase, CC = calcite.
