Reservoir Potential in Contourites: Evidence of Coarse-grained Contourite Facies in the Mozambique Margin

Proceedings, 2018
Summary Although contourites and mixed turbidite/contourite depositional systems are significant to the oil industry, they are still relatively poorly known by this sector, and there is no present-day accepted sedimentological model for sandy contourites.

Thin Bed Contourite Seismic Imaging

Proceedings, 2013
Wavelet (Mathematical Microscope) analysis of seismic data is made fashionable for thin bed precise subsurface imaging and interpretation. 3D seismic data interpretation for subsurface imaging of thin bed contourite systems is integral part of research work .

Contour Currents and Contourite Drifts

2011
Abstract This chapter provides a current state-of-the-art on the contourite systems with a major focus on the modern systems (drifts), the processes of deposition and the diagnostic sedimentological and seismic features. A short overview of the ancient contourite problem is also provided. Firstly, the history of contourites is briefly reminded since

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 ...

Contourite Drifts and Associated Bedforms

2017
Contourites, also known as alongslope deposits, are sediments that have been deposited or significantly affected by the persistent action of contour (bottom) currents. Contourite drifts are the large-scale morphological expression of contourite deposition, up to 106 km2 in area and >1 km in thickness.

Chapter 20 Shallow-Water Contourites

2008
Publisher Summary This chapter focuses on some quaternary examples of shallow-water contourites from a wide variety of quaternary geological settings such as the outer shelf of the SE-African continental margin and the Mediterranean shallow-water contourite deposits.

Chapter 18 Abyssal Plain Contourites

2008
Publisher Summary Abyssal plain contourites are of great significance for palaeoceanographic reconstructions. Ocean basins in general and abyssal plains in particular contain extensive sheeted depositional systems characterized by many thin-bedded-distal turbidites, rare but very large-scale megaturbidites, and interbedded-hemipelagic and pelagic ...

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.

Chapter 21 Mixed Turbidite–Contourite Systems

2008
Publisher Summary Turbidity currents are energetic unsteady processes with velocities usually ranging from a few decimetres, toa few metres or a few tens of metres per second. This chapter illustrates the low-frequency contourite and turbidite alternations; high-frequency contourite and turbidite alternations; redistribution of gravity deposits by ...
