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

open access: yesThe 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 ...

Bahaman patch reefs: Numerous and neglected

open access: yesThe 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?

Newly Discovered Triassic Lithium Deposits in the Dahongliutan Area, NorthWest China: A Case Study for the Detection of Lithium-Bearing Pegmatite Deposits in Rugged Terrains Using Remote-Sensing Data and Images

open access: yesFrontiers in Earth Science, 2020
Rare metals, such as lithium and cobalt used in rechargeable batteries, have increased in value as demands for them escalates. Concentrations of lithium-bearing minerals are found in closed-basin brines, granitic pegmatites, and associated granitic rocks

A bird-like skull in a Triassic diapsid reptile increases heterogeneity of the morphological and phylogenetic radiation of Diapsida [PDF]

open access: yesRoyal Society Open Science, 2017
The Triassic Period saw the first appearance of numerous amniote lineages (e.g. Lepidosauria, Archosauria, Mammalia) that defined Mesozoic ecosystems following the end Permian Mass Extinction, as well as the first major morphological diversification of ...

The stratigraphy of the Penarth Group (Late Triassic) of the East Devon coast [PDF]

open access: yes, 2008
The cliff and foreshore exposures in the Devon part of the Dorset and East Devon Coast World Heritage Site expose an unbroken late Triassic to early Jurassic succession.

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

open access: yesThe 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.

A new stem group echinoid from the Triassic of China leads to a revised macroevolutionary history of echinoids during the end-Permian mass extinction [PDF]

open access: yesRoyal Society Open Science, 2018
The Permian–Triassic bottleneck has long been thought to have drastically altered the course of echinoid evolution, with the extinction of the entire echinoid stem group having taken place during the end-Permian mass extinction. The Early Triassic fossil

Ichnological discrimination of hemipelagic‐dominated slope versus basin‐floor mudstones: Insights from early Viséan successions of a distally steepened ramp, northern Iran

open access: yesThe Depositional Record, EarlyView.
This study integrates sedimentological and ichnological data to reveal the depositional processes and environmental conditions of deep‐water muddy gravity flows in the Mobarak Formation. It highlights distinct ichnocoenoses and bioturbation patterns, offering insights into basin‐floor versus slope mudstones and their implications for hydrocarbon ...

Black shale deposition during the Early Jurassic: Geochemistry of Pliensbachian and Toarcian sedimentary rocks of the Hunzen Well, Hils Syncline, Northwest German Basin

open access: yesThe Depositional Record, EarlyView.
Our research uses a multidisciplinary approach, including organic and inorganic geochemistry, biostratigraphy, carbon isotope geochemistry and organic petrography to reconstruct depositional conditions and organic matter accumulation during the Pliensbachian and Toarcian.

A Triassic land-surface [PDF]

open access: yesTransactions of the Edinburgh Geological Society, 1894
1. There are few subjects in Geology more fascinating than the study of the physical features of the earth's surface in remote periods of its history. Such studies are perhaps usually successful when pressed no further back than Post-Tertiary or Pliocene time, since which in our islands, the development of their scenery has proceeded continuously on ...
