Metallogenic Fingerprints of the Congo Shield with Predictions for Mineral Endowment Beneath the Congo Basin - Geology and Resource Potential of the Congo Basin - page 387

Fig. 19.6 Mineral diversity in
Congo Basin, as shown by
plotting the (natural log, Y-axis)
spatial coeffient (ln r ij ) of the five
element groups (and the total of
these groups [lower most plot]).
Confidence intervals

Standard Error. Note how each
geologic domain has a unique
combination of elements that we
term their ' Metallogenic
fingerprint ' . Note that if the
confidence interval include 0, the
fingerprint is classed as random
