Fossil Contourites in Lower Niesenflysch, Switzerland

SEPM Journal of Sedimentary Research, 1972
ABSTRACT The lower part of the Maastrichtian-Paleocene Niesenflyseh near Adelboden, Switzerland, consists of shale and shale--sandstone alternations. The sandstone beds normally are 4 to 5 cm thick, have distinct upper and lower bedding planes and are rather well sorted.

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.

Contourite Anticlines as Exploration Objectives: ABSTRACT

AAPG Bulletin, 1979
Regional seismic profiles off the east coast of the United States gathered by the University of Texas Marine Science Institute and Woods Hole Oceanographic Institute have crossed three types of contourite anticlines. They are symmetric, asymmetric, and half-anticlinal forms and have up to 3,000 ft (1,000 m) of relief.

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 ...

Chapter 9 The Nature of Contourite Deposition

2008
Publisher Summary Contourites occur closely interbedded with the other deep-water facies. They range from very fine-grained to relatively coarse-grained deposits and include siliciclastic, bioclastic, volcaniclastic, and chemogenic compositional varieties. This chapter reviews the depositional mechanisms of contourites at the large, intermediate, and

Chapter 3 Methods for Contourite Research

2008
Publisher Summary This chapter illustrates the range of techniques that can be employed to investigate contourite sedimentation in the deep sea using hydrographic, geophysical, and sedimentological studies. The range of processes contributing to current-influenced sedimentation in the deep sea can be extremely diverse and at a variety of scales from ...

Chapter 23 Economic Relevance of Contourites

2008
Publisher Summary This chapter discusses the economic relevance of contourites. The recognition of the economic significance of contourites is pushed forward due to the continuous advance of hydrocarbon exploration toward deeper waters and the need to better determine the origin of some reservoir deposits lacking “typical” turbidite signature.

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 ...

Chapter 10 Traction Structures in Contourites

2008
Publisher Summary This chapter reviews the traction structures in contourites that are formed in deep marine systems under the influence of oceanic bottom currents. Some general and theoretical constraints on the range of likely processes forming primary sedimentary structures in contourites are established.
