Time
Period:Neogene Epoch:Miocene
10 m.y. bin:Cenozoic 5
Key time interval:Burdigalian - Langhian
Age range of interval:20.44000 - 13.82000 m.y. ago
Age estimate:16.33 ± 0.11 to 15.43 ± 0.09 Ma (Sr isotope)
Stratigraphy
Formation:Castilletes
Local section:Patajau Sur (430103) Local bed:80 m
Local order:bottom to top
Stratigraphic resolution:bed
Stratigraphy comments: Stratigraphic section Patajau Sur (430103) of Moreno et al (2015).
A mean age of 16.2 Ma (range of 16.33 ± 0.11 Ma–16.07 ± 0.10 month year) is calculated
for beds in the Patajau Valley near the base of the formation, on the basis of 87Sr/86Sr ratios. Beds in the middle part of the formation near Makaraipao yielded a mean 87Sr/86Sr ratio-derived age of 15.30 Ma (range of 15.14 ± 0.13 Ma–15.43 ± 0.09)
