Stratigraphy
Geological group: | Peninj | Formation: | Humbu | Member: | Middle Zone |
Stratigraphy comments: ETE dating method: absolute, ETE age comment: Was-Mbugu olivine basalt smpls(1964&1969 Isaac) radiometric intage_max, radiometric intage_min
Was originally under Hubu Formation. Base of formation is about ~1.75Ma, the Main Tuff is ~1.19+/-0.03Ma. The top of the Peninj Group is about 1.01+/-0.03Ma, therefore, the upper dsands are ~1.2-1.1Ma (Deino et al. 2006) |
