Abstract The Neoproterozoic Sete Lagoas Formation ( ca 610 Ma) of the São Francisco Basin, Brazil, is a succession siltstone, limestone and phosphorite. Phosphorite forms part previously unrecognized 150 to 200 m thick, unconformity bounded depositional sequence. Lithofacies stacking patterns indicate that deposition was punctuated by higher order fluctuations in base level produced aggradational parasequences. These shallowing‐upward cycles record progradation phosphate‐rich intertidal...
