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 ...

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 19 Continental Slope Contourites

2008
Publisher Summary Contourite systems are common on many slopes and show both depositional and erosional features. This chapter summarizes key case studies in different slope settings and discusses general and specific characteristics of different types of slope contourites.

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.

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.
