Biogeography of benthic foraminifera in contourite drift systems

2021
<div> <p><span>Benthic foraminifera colonize a wide range of marine environments, including contourite drift systems (CDS). CDS are characterized by sustained bottom currents and cover large areas on the seafloor, e.g., in the North Atlantic.

Identification of fossil contourite drifts in the Delaware Basin, U.S.A.

Journal of Sedimentary Research, 2022
ABSTRACT Carbonate contourite drifts formed by bottom currents are common on modern sea floors but are rarely defined in the rock record. Regional subsurface well-log mapping in the northern Delaware Basin in southeast New Mexico, USA, reveals early Permian carbonate-dominated elongate, mounded accumulations along the slope of the ...

Characteristics of modern carbonate contourite drifts

Sedimentology, 2019
AbstractCarbonate environments inhabit the realm of the surface, intermediate and deep currents of the ocean circulation where they produce and continuously deliver material which is potentially deposited into contourite drifts. In the tropical realm, fine‐grained particles produced in shallow water and transported off‐bank by tidal, wind‐driven, and ...

Seismic features diagnostic of contourite drifts

Marine Geology, 1999
Abstract The sedimentary construction of oceanic margins is most often carried out by the combined action of gravitational processes and processes related to bottom (contour) currents. One of the major difficulties encountered in the interpretation of seismic profiles crossing such margins is the differentiation of these two types of deposit ...

The Lofoten contourite drift off Norway

Marine Geology, 1999
Abstract Based on high-resolution and multichannel seismic data, a contourite drift, the Lofoten Drift, has been identified below ca. 1000 m water depth on the continental slope off Norway. The Lofoten Drift has a maximum thickness of about 360 m. Correlation to published seismic stratigraphy implies a Neogene age.

Contourite Drifts in the Tartar Strait, Sea of Japan

Doklady Earth Sciences, 2020
Contourite drifts were first detected in the Tatar Strait in the framework of the Sakhalin Slope Gas Hydrates International Project (2012–2015). The number of unconformities observed inside the drifts indicates variations in the hydrological regime and sedimentary supply over at least 1 Ma.
