Figure 5

Discriminant-function multidimensional diagrams based on ln-transformed ratios of immobile trace elements for tectonic discrimination of intermediate Sierra de las Cruces magmas. The symbols are explained as inset in (a); more details are in Figure 3. The subscript “tint” in axis names refers to trace (t) element ratios for intermediate (int) magmas.
