North Atlantic contourite sand channels

Geological Society, London, Special Publications, 2007
Abstract Two sand-rich channelized depositional systems, formed by strong contour currents, were studied west of the Faeroe Bank Channel and in the Gulf of Cadiz. Both are areas beyond the exit of constrictions where water overflows from the Norwegian Sea and the Mediterranean Sea, respectively.

Contourite facies model: Improving contourite characterization based on the ichnological analysis

Sedimentary Geology, 2019
Abstract The calcareous contourites from the Late Oligocene and Early Miocene in the Petra Tou Romiou type section (southern Cyprus) have been studied in detail, being regarded as outstanding examples of fossil bioclastic contourites and representative of the standard facies model of contourite bigradational sequence. These bigradational sequences of

Fossil contourites: a critical review

Sedimentary Geology, 1998
Abstract Despite three decades of study, there is still great controversy over the recognition and interpretation of fossil contourites exposed in ancient series on land. In order to best examine this problem, we briefly review the evidence from modern systems, including the many examples of Cenozoic contourites that have been recovered from DSDP/ODP

North Atlantic contourites: an overview

Geological Society, London, Special Publications, 1984
Summary We present a brief overview of known bottom circulation and Tertiary to Recent sediment drifts in the North Atlantic Ocean, and outline the distinctive features of contourite sediments recovered from these drifts. There is a gradation of structural and textural characteristics between the finer-grained clayey and muddy contourites and

Contourites in Lake Superior

Geology, 1980
Contour currents influence sedimentation in an area 15 km wide and 65 km long at the base of the slope off the Keweenaw Peninsula in Lake Superior, northwestern Michigan. Seismic-reflection profiles (3.5 kHz) from this area show distinct wavy reflectors in a scoured trough at a depth of 200 m at the base of the slope, hyperbolic echoes adjacent to the ...

Contourites in the Fram Strait

Sedimentary Geology, 1993
Abstract Multichannel seismic reflection profiles from the Fram Strait show many features that can be attributed to bottom-current influence on the sediments, by comparison with well-known contourite sequences elsewhere. A greater than 2 km thick contourite drift with a smooth internal reflection pattern is observed northwest of Svalbard.

Identification of ancient sandy contourites

Geology, 1981
Proposed criteria for the identification of ancient sandy contourites include occurrence (thin beds, reworked sandy turbidites, coarse lag), structure (bioturbated, no regular vertical sequence, orientation of cross-lamination perpendicular to regional downslope paleocurrents), grain size (silt or sand, little mud, low or negative skewness), fabric ...

Muddy contourites in the Baltic Sea: an example of a shallow-water contourite system

Geological Society, London, Memoirs, 2002
Abstract Bottom currents in the Baltic Sea have had a pronounced effect on the nature and distribution of sediments throughout the Holocene. Due to the intermittent nature of water exchange between the North and the Baltic Seas, the flow of bottom currents is impermanent.

Chapter 22 High-Latitude Contourites

2008
Publisher Summary This chapter provides an overview of the best-known Neogene and Quaternary glacigenic contourite deposits in both hemispheres. The Antarctic continental margin and the northern North Atlantic Margin are considered. In mid- to high-latitude areas, an ice-rafted component is commonly presentwithin sedimentary drifts deposited or ...
