Discovery of Late Holocene‐aged Acropora palmata reefs in Dry Tortugas National Park, Florida, USA: The past as a key to the future?

open access: yesThe Depositional Record, EarlyView.
Emblematic of global coral‐reef ecosystem decline, the coral ecosystem‐engineer Acropora palmata is now rare throughout much of the western Atlantic. We report for the first time, a significant record of late‐Holocene A. palmata populations that existed from ~4500 to 375 years before present in the Dry Tortugas, FL, USA.

The role of refluxing deep hypersaline brines and evaporite precipitation dynamics in the Castile Formation and marginal carbonate strata (Delaware Basin, USA)

open access: yesThe Depositional Record, EarlyView.
The Upper Permian Castile Formation of the Delaware Basin, a 515.3 m (1690.6 ft) thick deep‐water evaporitic sequence dominated by anhydrite and halite, is the focus of this study. This study's sedimentological and geochemical analysis of cores from the basin's centre and margin reveals that dynamic reflux of deep hypersaline brines significantly ...

Lacustrine and fan‐delta sediments in syn‐rift lake basins

open access: yesThe Depositional Record, EarlyView.
A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...
