Integrated Ichnofacies models for deserts: Recurrent patterns and megatrends [PDF]

Earth-Science Reviews, 2016
Abstract Although it is commonly assumed that the trace-fossil record of eolian dunes and associated environments is invariably poor, a systematic review of the available information indicates that this is not necessarily the case. A model involving five main phases of colonization of desert environments through the Phanerozoic is proposed in this ...

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

The Depositional Record
Integrating sedimentological and ichnological data from the uppermost unit of the Mobarak Formation (early Viséan, Northern Iran), deposited in a distally steepened ramp, provides insights into deep‐water muddy gravity flows in mud‐rich slope settings ...

Firmground ichnofacies recording high-frequency marine flooding events (Langhian transgression, Vallés-Penedés Basin, Spain) [PDF]

Geologica Acta, 2005
The decapod burrow Spongeliomorpha sudolica occurs associated with transgressive firmgrounds in the transition between Aragonian continental red beds and Langhian marine units in some of the inner sectors of the Vallès-Penedès Basin.

Use of Lithofacies and Ichnofacies in Interpreting the Nise Formation

, 2020
Niseformasjonen ble avsatt på den midt-norske kontinentalsokkelen fra Santon til Campan. Niseformasjonens avsetningsmiljø har lenge vært preget av ulike tolkninger, som har plassert formasjonen fra “åpen sjø” til dypere bassenggulv. Tolkningene varierer selv om de samme geologiske strukturene har blitt betraktet.

Distinguishing between Deep-Water Sediment Facies: Turbidites, Contourites and Hemipelagites

Geosciences, 2020
The distinction between turbidites, contourites and hemipelagites in modern and ancient deep-water systems has long been a matter of controversy. This is partly because the processes themselves show a degree of overlap as part of a continuum, so that the

Lithofacies and ichnofacies of turbidite deposits, West Java, Indonesia [PDF]

Fossil Imprint, 2021
This study focuses on the analysis of sedimentary facies and ichnogenus variations to determine the palaeogeographic setting of turbidite deposits that are clearly exposed in the surroundings of Majalengka area, West Java, Indonesia. Lithofacies variation in turbidite deposits, identified from detailed stratigraphic sections, were visually presented as

Unconformity generation and the shift from storm‐dominated to tide‐dominated processes in a Jurassic retroarc foreland basin: Insights from ichnology

The Depositional Record, 2023
An enigmatic transition from the storm‐dominated, offshore to lower shoreface deposits of the Redwater Shale Member (Sundance Formation) to the overlying mixed tidal and aeolian Windy Hill Sandstone (Morrison Formation) in the Oxfordian of the North ...

Aptian–Albian deposits of the Ait Ourir basin (High Atlas, Morocco): New additional data on their paleoenvironment, sedimentology, and palaeogeography

Open Geosciences, 2020
This sedimentological and palaeontological analysis of the Aptian–Albian sedimentary succession of the Ait Ourir basin in the High Atlas Mountains of Marrakesh in Morocco provides new data from a previously poorly understood basin.
