Confined Turbidite Systems
This publication reflects a growing appreciation of the extent to which turbidite depositional system development is fundamentally affected by basin-floor topography. In the many turbidite and turbidite hydrocarbon reservoirs, depositional patterns have been moderately to strongly confined by pre-existing slopes; thus ‘submarine fans’ may be far from fan-shaped where constrained by significant bathymetric features. This volume examines aspects of sediment dispersal and accumulation in deep-water systems where sea-floor topography has exerted a decisive control on deposition, and explores the associated controls on hydrocarbon reservoir architecture and heterogeneity.
The papers presented here offer a global perspective, which is wide-ranging in terms of approach as well as location, including contrasting reviews and case studies of outcrop, subsurface, modern and experimental systems. This book will be of use both to academic geologists and to geoscience professionals in industry dealing with characterization and modelling of deep-water clastic reservoirs.
Submarine fans within small basins: examples from the Tertiary of New Zealand
Published:January 01, 2004
This study uses the example of two small sedimentary basins to draw lessons for the stacking patterns of submarine fan facies in restricted basins. The Te Anau and Waiau basins are located in southwest New Zealand. They developed from the Middle Eocene onwards close to and under the direct influence of the evolving Australia-Pacific plate boundary. Although never more than a few tens of kilometres wide, both basins accumulated sedimentary successions more than 6 km thick. We discuss the scale, nature and composition of submarine fans within the basins. Sediment stacking patterns are characterized by rapid lateral and vertical...
