FIG. 6. Geochemical plots showing the relationship between Au and Cu enrichment and enrichment in Ce and La in the host volcanic rocks and the mineralized breccias. A. Log-log plots: A. Ce (ppm) vs. Au (ppm). B. La (ppm) vs. Cu (wt %). Plots illustrate the strong correlation of REE with Au and Cu and hence the likelihood that monazite is related to Cu-Au mineralization.
