A coherent middle Pliocene magnetostratigraphy, Wanganui Basin, New Zealand [PDF]

, 2005
We document magnetostratigraphies for three river sections (Turakina, Rangitikei, Wanganui) in Wanganui Basin and interpret them as corresponding to the Upper Gilbert, the Gauss and lower Matuyama Chrons of the Geomagnetic Polarity Timescale, in ...

Discrete Dynamical Models Showing Pattern Formation in Subaqueous Bedforms [PDF]

, 1993
A new class of ``toy models'' for subaqueous bedform formation are proposed and examined. These models all show a similar mechanism of wavelength selection via bedform unification, and they may have applications to bedform stratigraphy. The models are also useful for exploring general issues of pattern formation and complexity in stochastically driven ...

Linking uplift, erosion, and sedimentation using landscape evolution models: Madagascar since the Late Cretaceous

Earth Surface Processes and Landforms, Volume 48, Issue 1, Page 215-229, January 2023., 2023
This paper uses a numerical landscape evolution model to reconstruct the topographic history of Madagascar since the Late Cretaceous. The model is optimised by balancing the volumes of onshore erosion and offshore sedimentation; the former is predicted with erosion laws and based on uplift history inferred from elevated planation surfaces.

Effects of Stratigraphy on Response of Energy Piles [PDF]

arXiv, 2022
Energy piles are gaining increased popularity due to a growing demand for clean energy. To further advance the understanding of soil-structure interaction in energy piles, recently-derived analytical solutions have been implemented to investigate the impact of stratigraphy on the soil-structure interaction.

Geoarchaeological characterisation of a Younger Dryas site in the Alpine uplands: Cornafessa rock shelter (Italy)

Geoarchaeology, Volume 38, Issue 1, Page 35-56, January/February 2023., 2023
Abstract The effects of the Younger Dryas (YD) fluctuation on Late Pleistocene hunter‐gatherers' settlement and subsistence systems in the southern Alps are poorly known. This is primarily due to the scarcity of archaeological sites dating from the YD, in contrast with the extensive evidence available from the lateglacial interstadial and the early ...

Biostratigraphy of the Small Shelly Fossils From the Upper Maidiping Formation (Terreneuvian) at the Fandian Section, Sichuan Province, South China

Frontiers in Earth Science, 2022
Small shelly fossils (SSFs) are a useful and critical tool for subdivision and correlation of the Cambrian Terreneuvian stratigraphy. The Maidiping Formation in southern Sichuan is a well-known Terreneuvian lithologic unit with rich SSFs. Here, the upper

Ontogeny of the malleus in Mesocricetus auratus (Mammalia, Rodentia): Systematic and functional implications for the muroid middle ear

The Anatomical Record, EarlyView.
Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...

Comparing different machine‐learning techniques to date Nile Delta sediments based on portable X‐ray fluorescence data

Geoarchaeology, Volume 38, Issue 1, Page 57-75, January/February 2023., 2023
Abstract Geomorphology generally aims to describe and investigate the processes that lead to the formation of landscapes, while geochronology is needed to detect their timing and duration. Due to restrictions on exporting geological samples from Egypt, modern geoscientific studies in the Nile Delta lack the possibility of dating the investigated ...

Revisit the Sedimentary Stratigraphic Evolution and Environmental Changes on the Outer Shelf of the East China Sea Since MIS 5

Frontiers in Marine Science, 2022
The East China Sea (ECS) is featured by the broad continental shelf, huge terrigenous sediment input and striking river-sea interaction during the Quaternary.

An integrated sequence stratigraphic, palaeoenvironmental, and chronostratigraphic analysis of the Tangahoe Formation, southern Taranaki coast, with implications for mid-Pliocene (c. 3.4–3.0 Ma) glacio-eustatic sea-level changes [PDF]

, 2005
Sediments of the mid-Pliocene (c. 3.4–3.0 Ma) Tangahoe Formation exposed in cliffs along the South Taranaki coastline of New Zealand comprise a 270 m thick, cyclothemic shallow-marine succession that has been gently warped into a north to south trending,
