The volcanic geology of the Pahranagat Range and certain adjacent areas, Lincoln County, southeastern Nevada

Extended reconnaissance over 700 square miles of the Pahranagat, Alamo and Hiko Ranges has revealed that more or less continuous emission of fissure type nuees ardentes has been punctuated by periods of fluvio-lacustrine deposition of reworked volcanic ejecta. Use of the exceptional value of ignimbr...
