Manual hierarchical clustering of regional geochemical data using a Bayesian finite mixture model
... In cluster 1, the enriched elements include Mo, As, Cd, Sb, S, Bi, Li, Cr, Ni, V, Cu, Zn, Sc, Co, Fe, and P ( Fig. 5 a). These elements are all commonly enriched in shales and other fine-grained marine sedi- mentary rocks ...
