Stratigraphy
Formation: | Maboko | ||||
Stratigraphy comments: ETE dating method: composite, ETE age comment: Max age = ~17 Ma based on biostratigraphy. Min age = 11.8 +/- 1.0 my (K/Ar date on Majiwa phonolite) radiometric intage_min
From Mayr et al. 2014: The Maboko Formation originated about 14-15 million years ago (Feibel and Brown, 1991; Retallack et al., 2002; Geraads et al., 2012); its age thus corresponds with the level MN5 of the European mammalian stratigraphy (Daams et al., 1999). |
