Geochronology of the pre-KBS Tuff sequence, Omo Group, Turkana Basin
The Omo-Turkana Basin of northern Kenya and southern Ethiopia developed in the northern Kenya Rift about 4.3 Ma ago in the Early Pliocene. Nearly 800 m of sediments, included within the Omo Group, crop out in the basin. Numerous rhyolitic tuffs in the sequence not only have facilitated secure correlations between the formations of the Omo Group but also have provided material for precise40Ar/39Ar age measurements. Here we report ages on alkali feldspar crystals from pumice clasts within tuffs...[Show more]
