- •
Carbonate- and silicate-derived Sr records in a fluvial sequence with paleosols.
- •
Tectonic forcing climatic drying and weakened weathering at around 8.6 Ma.
- •
Steady-state geomorphic regime broken at 8.6 Ma and re-established at 7.4 Ma.
- •
Eu/Eu*, Rb/Sr and 87Sr/86Sr in silicate effectively reveal provenance and sorting.
- •
Sr in carbonate impacted by pedogenesis at section site and catchment weathering.
