- •
The Nobres Fm. is characterized by shallowing upward cycles from arid tidal flats.
- •
The cyclicity patterns suggest accommodation by sea-level changes and subsidence.
- •
Carbonate production was eliminated by terrigenous input.
- •
Our data do not support the pre-glaciation Gaskiers influence within the Nobres Fm.
