Multivariate Analysis, Mass Balance Techniques, and Statistical Tests as Tools in Igneous Petrology: Application to the Sierra de las Cruces Volcanic Range (Mexican Volcanic Belt)
Figure 7
Discriminant-function multidimensional diagrams based on ln-transformed ratios of immobile major and trace elements for tectonic discrimination of acid Sierra de las Cruces magmas. The symbols are explained as inset in (a); more details are in Figure 6. The subscript “mtacid” in axis names refers to major (m) and trace (t) element ratios for acid (acid) magmas.
