Comparing Aggradation, Superelevation, and Avulsion Frequency of Submarine and Fluvial Channels

open access: yesFrontiers in Earth Science, 2020
Constraining the avulsion dynamics of rivers and submarine channels is essential for predicting the distribution of sediment, organic matter, and pollutants in alluvial, deltaic, and submarine settings.

An early Proterozoic metagreywacke-slate turbidite sequence: The Tampere schist belt, southwestern Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1986
The metasedimentary sequence of the Tampere Schist belt, where it has undergone only slight metamorphism, clearly consisted of graded graywackes, siltstones and mudstones.

A workflow for turbidite reservoir characterization—a case study of the Macedon member, Northern Carnarvon Basin, NW Australia

open access: yesFrontiers in Earth Science, 2023
Deep-water turbidite systems on passive continental margins are of interest for oil and gas exploration. However, their complexity poses challenges for reservoir characterization.

Effective techniques for seismic description of reservoirs in Jiyang Depression, Bohai Bay Basin

open access: yesShiyou shiyan dizhi, 2021
A series of 3D seismic descriptions for five reservoir types in the Jiyang Depression of Bohai Bay Basin was proposed based on the comparison and analysis of a large amount of drilling and seismic data. The effective techniques for seismic description of

Superposed Sedimentary and Tectonic Block-In-Matrix Fabrics in a Subducted Serpentinite Mélange (High-Pressure Zermatt Saas Ophiolite, Western Alps)

open access: yesGeosciences, 2019
The primary stratigraphic fabric of a chaotic rock unit in the Zermatt Saas ophiolite of the Western Alps was reworked by a polyphase Alpine tectonic deformation.

Architectural Diversity of Submarine Lobate Deposits

open access: yesFrontiers in Earth Science, 2021
Lobate deposits in deep-water settings are diverse in their depositional architecture but this diversity is under-represented in the literature. Diverse architectures result from multiple factors including source material, basin margin physiography ...

Impact of turbulence on magnetic alignment in sediments

open access: yesFrontiers in Earth Science, 2022
Rapidly deposited layers (RDL) such as turbidites or hyperpycnites are mostly studied for their sedimentological properties, but are carefully avoided in paleomagnetic studies due to the disturbances caused by such sudden and rapid sediment accumulation.
