Correlation of ignimbrites using paleomagnetism and 40Ar/39Ar dating
William C. McIntosh New Mexico Bureau of Mines and Mineral Resources, Socorro, NM, 87801 Paleomagnetic studies and 40Ar/ 39Ar dating are powerful, reliable techniques for correlation of Oligocene ignimbrites (ash-flow tuffs) in the Mogollon-Datil volcanic
