![]() ![]() Fossil ages are based on diatom and mollusk assemblages. Our study incorporates geologic mapping with age control based on new radiometric ages as well as paleontology, Flows and tuffs were dated by the K-Ar method. ![]() Located just a 20-minute drive outside of Ensenada in Baja California Norte, Valle De Guadalupe is the new cool spot to visit. Recently determined radiometric ages and chemical analysis of volcanic rocks were reported by Hausback (1984) and by Sawlan and Smith (1984). Baja California Map With Top Things To See & Do: 1. The first radiometric ages of rocks from the map area were published by Gastil and others (1979).

Focus was placed on determining the distribution and age of plateau-capping basalts, and on mapping the eastern limits of Paleogene marine strata and the western limits of the nonmarine Comondu Formation. The reconnaissance geology of part of the San Isidro 1:250,000-scale quadrangle of Baja California Sur, Mexico, was mapped in 1982, 1983, and 1984 to determine the age and stratigraphic relations of Tertiary sedimentary and volcanic rocks that comprise the bulk of the Sierra de la Giganta (southern Peninsular Ranges) and Pacific coastal plain. ![]()
