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) |
