Welded tuffs of Chiricahua National Monument, Arizona
Enlows HE. 1955. Welded tuffs of Chiricahua National Monument, Arizona. Geological Society of America Bulletin. 66(10):1215-1246
This document examines the weathering and geologic distribution of the welded ryolite tuffs of Chiricahua National Monument. "Chiricahua National Monument, Arizona, and much of the western part of the Chiricahua Mountains contain extensive bedded rhyolite deposits of Cenozoic age heretofore termed flows. Most of these volcanic rocks, however, are more correctly classified as welded rhyolite tuff or ignimbrite, the result of many eruptions of nuies ardentes...Study of the petrography, structure, conditions of deposition, and origin of this unusually thick section of rock permits an evaluation of features which have been termed characteristic of welded tuffs, and facilitates identification of this important rock type." Illustrations, map, and tables.
