Sedimentological characterisation is a necessary prerequisite for interpretation of stable carbon isotope ratios of bulk sediment from reefal settings

Sedimentology, EarlyView.
ABSTRACT For most of Earth history, carbonate sediments deposited in shallow marine settings are the only remaining archive of changing biogeochemical cycles. All deep‐sea sediments older than >200 Ma have been subducted and are therefore lost from the record. Stable carbon isotope (δ13C) values of shallow marine carbonates are available for older time

Facies mosaic distribution and stratigraphic disorder of a mixed carbonate–siliciclastic tidal succession

Sedimentology, EarlyView.
ABSTRACT Complex stratigraphic arrangements may be generated through lateral facies transitions from the strata of aeolian depositional systems into bordering peritidal deposits. In such scenarios, sedimentary architectural complexity and associated facies heterogeneities are governed by the interplay between autogenic processes inherent to tidal ...

Aligned hydrothermal fluid‐flow pathways in Middle Permian near‐shore marine sediments beneath a basaltic lava flow

Sedimentology, EarlyView.
ABSTRACT Tubular and curviplanar structures, outlined by the occurrence of haematite/goethite, chlorite, quartz and albite, are developed in the Middle Permian Broughton Formation in the southern Sydney Basin, New South Wales, Australia. These structures are interpreted as fluid‐flow pathways resulting from the ejection of heated pore fluids as a thick

Microbially generated ferruginous crusts: A potential biosignature of continental input in coastal settings

Sedimentology, EarlyView.
ABSTRACT Thin ferruginous sandy crusts are common on top of sandstone beds in the Early Permian post‐glacial deposits of the Paraná Basin in southern Brazil. These crusts usually preserve wrinkle structures, suggesting that they might be a product of microbial mediation.
