A thick sequence of bedded pyroclastic-surge deposits is exposed in the vertical western wall of La Joya Prieta maar in the Santo Domingo volcanic field in the southern Basin and Range province in the state of San Luis Potosí.  The Santo Domingo field contains a group of four maars, the largest of which is the 750 x 1000 m wide La Joya de los Contreras maar, along with several alkalic cinder cones and associated lava flows.  The Santo Domingo maars are the source of mantle-derived spinel-lherzolite xenoliths and deep-crustal granulite xenoliths. Photo by Jim Luhr, 1987 (Smithsonian Institution).
