Modern and ancient tidal sedimentary systems in the era of energy transition: Introduction to the special volume of The Depositional Record

The Depositional Record, EarlyView.
This volume examines tidal sedimentary systems through 11 articles, spanning ancient and modern tidalites, technological advances and implications for human management. Highlighting contributions from Tidalites 2022 and beyond, it underscores tidalites' significance in sedimentology, environmental forecasting and energy transition, reflecting decades ...

Gold and palladium as indicators of an extraterrestrial component in the Cetaceous/Tertiary boundary layer at Woodside Creek and Chancet Quarry, Marlborough, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Earth Sciences at Massey University [PDF]

, 1998
It is widely believed that a large meteorite approximately 10 km in diameter impacted Earth at the termination of the Cretaceous Period with cosmic velocity, vaporising itself, along with a greater mass of the terrestrial target rocks into a cloud of hot

Fifty years of research on the Joulters ooid sandbody—Impact on carbonate sedimentology and diagenesis and lessons learned from an invaluable analogue

The Depositional Record, EarlyView.
The Joulters ooid sandbody of northern Great Bahama Bank is a vast expanse of muddy ooid sands partly rimmed by clean ooid sands and formed into a relatively thick layer of significant extent. Knowledge of the development of depositional and diagenetic patterns in the Joulters example has forwarded our general understanding of carbonate sedimentology ...

Late Maastrichtian carbon isotope stratigraphy and cyclostratigraphy of the Newfoundland Margin (Site U1403, IODP Expedition 342) [PDF]

, 2018
Earth’s climate during the Maastrichtian (latest Cretaceous) was punctuated by brief warming and cooling episodes, accompanied by perturbations of the global carbon cycle.

Bahaman patch reefs: Numerous and neglected

The Depositional Record, EarlyView.
Abstract Phanerozoic patch reefs are extensively studied because they are abundant and are potential reservoirs for valuable fluids. In contrast, geologic studies of modern reefs have largely focused on platform margins, leaving patch reefs comparatively neglected. What conditions favour patch‐reef development?

A reappraisal of the Italian record of the Cretaceous pachycormid fish Protosphyraena Leidy, 1857 [PDF]

, 2017
The genus Protosphyraena is known mainly from partial remains, consisting of isolated blade-like teeth, conical rostra and scythe-like pectoral fins. This paper provides a new insight into partial specimens of the genus Protosphyraena from the Cretaceous

Water pathways and ancient lakes: Flowing towards new models to unravel the past

The Depositional Record, EarlyView.
Abstract Significant progress has been made in understanding lake basin evolution through climatic and tectonic changes using sedimentology, sequence stratigraphy, geochemistry, hydrology and watershed characteristics to interpret three main lake basin types: overfilled, balanced‐fill and underfilled, including fluvio‐lacustrine systems.
