F ig . 13. Plot of factor loadings for factors 1 and 2 from the factor analysis of humus samples from the Baker-Shorty Lake area in the Lac des Iles property. The factor loadings are listed in Table 5 . The factor analysis was conducted using the Systat 10.2 computer program.

Table 2.  Character groupings delineated by principal components analysis (SYSTAT 2004). Data consisted of 34 characters measured or counted in 211 specimens representing 16 species-level taxa of Peronopora . Characters were standardized by range, and rotated (varimax) loadings were used

Cluster analysis diagrams showing overall mineral chemistry relationships among samples based on average (a) orthopyroxene, (b) plagioclase, (c) augite, and (d) orthopyroxene + plagioclase compositions. Diagrams were constructed using average mineral compositions for each sample. Numbers of analyses used to create averages appear in Table 1. Only elements detected in over 90% of analyses for a particular mineral were included in averages. Thus SiO2, FeOt, and CaO were used in all averages; MgO in orthopyroxene and clinopyroxene averages; Na2O in plagioclase and augite averages; and TiO2 in augite, MnO in orthopyroxene, and K2O in plagioclase averages. Each major-element oxide (wt. %) in a mineral average was z-scored to give it equal weight in determining similarity. Clustering used Euclidean distances and the average linkage method in SYSTAT statistical software (Wilkinson et al. 1992).

Multidimensional scaling diagram showing overall geochemical relationships among samples. Samples plotting close to one another tend to be geochemically most similar. The diagram was prepared by averaging data for Egyptian (H, Haddadin; C, Cairo–Suez; B, Bahariya; S, Southern Egypt) and Jordanian bedrock units (J, Sweimeh/Ma’in; K, Kerak). Artefacts analyses were not averaged and are Egyptian paving stones (P), vessels from Abydos (A), a spindle whorl from Maadi (D), and a selection of Levant vessels (L). Element (Rb, Sr, Ba, Y, Zr, Nb, U, Th, Ti, V, Cr, Ni, Fe) concentrations were z-scored (put on the same scale) so that each contributed equally to the assessment of similarity. Distances between “samples” were determined from a matrix of Pearson’s correlation coefficients calculated for all possible sample-versus-sample pairs. Linear multidimensional scaling in two dimensions yielded a straight-line Shepard diagram with stress decreasing smoothly from 0.178 to 0.141. Data processing used SYSTAT statistical software (Wilkinson et al. 1992, pp. 109–131). See text for discussion.

Canonical scores plot of discriminant analysis (SPSS, 2000). Data used to construct canonical scores grid represent final iteration of Systat application. See Figure 5 for enlargement of Factor 2 versus Factor 1 (left-center cell in this figure). Total points = 156. Grid layout substitutes for three-dimensional diagram and shows all possible pairings of canonical variates Factor 1, Factor 2, and Factor 3. Ellipses showing 68% confidence limits represent cross sections of ellipsoidal clouds generated by discriminant analysis. In each grid cell containing confidence ellipses, selected canonical variates comprise horizontal and vertical axes. Note resemblance of cells that share identical axes. For example, in the left-center cell, Factor 1 is represented as the horizontal axis and Factor 2 is represented as the vertical axis; in the top-center cell, Factor 2 is represented as the horizontal axis and Factor 1 is represented as the vertical axis. Cells containing frequency curves represent cross-sections of ellipses in corresponding columns. The vertical axis of each bell-curve cell represents the score frequency of the corresponding variate, analogous to univariate frequency curves (compare Equation 4). Frequency-curve cells emphasize the contribution of each canonical variate to separation of groups (U, T, D, and B). Note significant separation in Factor 1 cell (upper left) relative to Factor 2 cell (center) and Factor 3 cell (lower right). Total number of points in each group corresponds to totals listed in Table 5. Group means for each factor are shown in Table 6. Group labels (B, D, T, and U) are shown below or above the mean value for each bell curve.
