The Zuni-Bandera Volcanic Field, west central New Mexico is a Quaternary aged volcanic field located in the transition zone between the Colorado Plateau and the Basin and Range. The field consists of a sequence of tholeiite and alkali basalt lava flows, spatter ramparts, scoria cones, shields, maars, and collapse pits erupting through Proterozoic continental crust. Basalts analysed in the area classify as basanite, trachybasalt/hawaiite, basalt, and basaltic andesite. Rocks belonging to the tholeiitic series are believed to be sourced from spinel-facies mantle whereas the alkaline series rocks were sourced from garnet-facies mantle. Geochemical data including whole rock major and trace element, Sr-Nd isotopic can be found in Menzies and Kyle (1991) and Peters et al. (2008).
