... dispersions. Spatter-dikes at the Castle Butte Trading Post volcanic complex (Hopi Buttes volcanic field, Arizona, USA), exposed ∼150 m below the paleosurface, present an outstanding record of this transition. They record pulsatory magma rise and eruption, fissure extension, vent stepping, and conduit wall...

.... The third phase deposited fine-grained material as flow waned in medial localities and was the only flow phase to reach the most distal sites. Newkirk (2009) returned to the Hopi Buttes to describe the lithosedimentary facies in a new area, Triplets Buttes, and to sample both his field area and Wood...

New U-Pb geochronology of variably deformed igneous and metasedimentary rocks constrains several periods of deformation at ca. 1.68 Ga, 1.66 Ga, and 1.49–1.45 Ga in the Four Peaks area of central Arizona. Detrital zircon analyses and field relationships indicate...

..., and geophysical study of the area indicates that the Solfatara volcano is a maar-diatreme structure previously not recognized within the Campi Flegrei caldera. It is characterized by a crater cut into earlier volcanic deposits, a small rim of ejecta, and a deep structure (down to 2–3 km). This maar-diatreme has...
