Integrated Stratigraphy and Fluvial Cyclicity of the Westphalian B in the southern North Sea Basin

ZHANG, LINZHI (author)

The upper Carboniferous in the southern North Sea, especially the Westphalian B and lower Westphalian C stage is characterized by the deposited cyclothems that are a series of coarsening-upward fluvial sediments cycles. These cyclothems are often coal-bearing and no more than 15 m. Studying the fluvial cyclicity has a good potential for improved...

Early post-rift depositional systems of the Central Atlantic: Lower and Middle Jurassic of the Essaouira-Agadir Basin, Morocco

Duval-Arnould, Aude (author), Schröder, Stefan (author), Charton, R.J.G. (author), Joussiaume, Rémi (author), Razin, Philippe (author), Redfern, Jonathan (author)

Passive margins are traditionally regarded as tectonically quiescent, however the increasing recognition of significant post-rift tectonic uplift along their flanks offers an important control on sediment delivery. The most extensive record of the early post-rift succession of the Central Atlantic Margin (CAM) is found in the Lower and Middle...

Long-eccentricity regulated climate control on fluvial incision and aggradation in the Palaeocene of north-eastern Montana (USA)

Noorbergen, Lars J. (author), Turtu, Antonio (author), Kuiper, Klaudia F. (author), Kasse, Cornelis (author), van Ginneken, Sverre (author), Dekkers, Mark J. (author), Krijgsman, Wout (author), Abels, H.A. (author), Hilgen, Frederik J. (author)

Aggradation and fluvial incision controlled by downstream base-level changes at timescales of 10 to 500 kyr is incorporated in classic sequence stratigraphic models. However, upstream climate control on sediment supply and discharge variability causes fluvial incision and aggradation as well. Orbital forcing often regulates climate change at...

Evaluating alluvial stratigraphic response to cyclic and non-cyclic upstream forcing through process-based alluvial architecture modelling

Wang, Y. (author), Storms, J.E.A. (author), Martinius, A.W. (author), Karssenberg, Derek (author), Abels, H.A. (author)

Formation of alluvial stratigraphy is controlled by autogenic processes that mix their imprints with allogenic forcing. In some alluvial successions, sedimentary cycles have been linked to astronomically-driven, cyclic climate changes. However, it remains challenging to define how such cyclic allogenic forcing leads to sedimentary cycles when...

The key role of crevasse splays in prograding river systems: Analysis of evolving floodplain accommodation and its implications for architecture and reservoir potential

van Toorenenburg, K.A. (author)

A generic life cycle applies to crevasse splays in non-degradational fluvial systems, typically ending in healing and abandonment. Crevasse-splay channels adjust to a graded equilibrium profile through proximal erosion and distal deposition, with their distal termini acting as a (prograding) local base level. When proximal incision advances to...

The Eridanos Delta: A Sequence Stratigraphic Study of the North Sea Upper Section with Focus on Shallow Gas Potential

Aljamed, Majid (author)

The Late Cenozoic Eridanos River brought vast amount of sediments to the North Sea Basin accumulating more than 1000m of deltaic deposits in less than 3.5 Ma. Since the gas discoveries in the shallow sediments were made, more attention is being paid to these deltaic deposits and that resulted in more data availability. <br/>This study...

Semi-automatic fold detection in geological outcrops using Laser Scanning data: Applied to a limestone-marl sequences in the Vocontian Basin, France

Roebroeks, Joppe (author)

Geological surveying is a common practice performed by geologists nowadays. Determining layer orientation parameters and identifying folds are examples of features needed in order to create a geological map or model of the (sub) surface. Surveying is expensive and time consuming, therefore such survey is recently being investigated and...

Influence of Mechanical Contrast and Confining Pressure on Fracture Behaviour in Layered Rocks

Regelink, Jaap (author)

A rock fracture is a mechanical break or discontinuity that separates a rock body into two or more parts. The continuity or cohesion of the rock body is lost across a fracture. Fractures are formed in response to stress on a rock. A rock breaks and forms a fracture when the applied stress reaches the rock strength. Vertical fractures improve...

Sequence stratigraphic analysis of Eridanos deltaic shallow gas-bearing deposits in North Sea: An insight into the shallow Dutch subsurface

Papatrecha, Natalia (author)

Growing interest has been expressed the last decades regarding the Late Cenozoic, gas-bearing sediments of Southern North Sea Basin. Comprising the shallow subsurface of the Dutch offshore sector, these sediments have<br/>been deposited by Eridanos fluvio-deltaic system, draining the Fennoscandian and Baltic shield through the present Baltic Sea...

A conceptual model for spatial Grain size variability on the surface of and within beaches

Gallagher, Edith (author), Wadman, Heidi (author), McNinch, Jesse (author), Reniers, A.J.H.M. (author), Koktas, Melike (author)

Grain size on the surface of natural beaches has been observed to vary spatially and temporally with morphology and wave energy. The stratigraphy of the beach at Duck, North Carolina, USA was examined using 36 vibracores (~1-1.5 m long) collected along a cross-shore beach profile. Cores show that beach sediments are finer (~0.3 mm) and more...

On the origin of crevasse-splay amalgamation in the Huesca fluvial fan (Ebro Basin, Spain): Implications for connectivity in low net-to-gross fluvial deposits

van Toorenenburg, K.A. (author), Donselaar, Rick (author), Noordijk, Niels (author), Weltje, G.J. (author)

Floodplain deposits are abundant in low-gradient dryland river systems, but their contribution to connected reservoir volumes has not yet been fully acknowledged due to their poor detectability with typical wireline log suites and relatively-lower reservoir quality. This study presents an analysis of stacked crevasse splays in the distal part of...

Geological characterisation of thin-bedded crevasse splay sandstones; outcrop-analogue studies for tough gas reservoir potential

Noordijk, N.A. (author)

Crevasse splay complexes in floodplain sequences are potential low net-to-gross tough gas reservoirs. The porosity and permeability of these reservoirs is low, but lateral amalgamation by compensational stacking can create extensive lobe-shaped sediment bodies with reservoir potential. The aim of this thesis is to characterize the development of...
