Abstract Tunnel valleys are elongated incisions that commonly interpreted as being the result of erosional processes by subglacial meltwater occurring under continental ice sheets. The abundance, size and primarily coarse-grained infill these features have made tunnel important hydrocarbon groundwater reservoirs. Although numerous been described over last century, their formation remain poorly understood. This review summarizes discusses current knowledge valleys, providing an overview...
ABSTRACT In the middle Green River Formation of central Nine Mile Canyon, Uinta Basin, Utah, several lacustrine-dominated intervals 10 m thick comprise aggradational carbonate parasequence sets and a progradational clastic parasequence. Maximum flooding surfaces are best identified within profundal oil shale that caps some parasequences. These lacustrine transgressive systems tracts therefore exhibit stacking patterns unlike typical marine sequences. Two types sequence boundary identified....
Abstract Two Palaeogene fluvial fan systems linked to the south‐Pyrenean margin are recognized in eastern Ebro Basin: Cardona–Súria and Solsona–Sanaüja fans. These had radii of 40 35 km were 800 600 2 area respectively. During Priabonian Middle Rupelian, fans built into a hydrologically closed foreland basin, shallow lacustrine persisted basin centre. In studied area, both part same upward‐coarsening megasequence (up m thick), driven by hinterland drainage expansion propagation Pyrenean...
Abstract The southern North Sea is a shallow epicontinental sea that was glaciated several times during the Quaternary. area known for its remarkable record of tunnel valleys, age and origin which are debated. recent availability continuous three-dimensional seismic data between coasts Britain Netherlands provides opportunity to establish new interpretation workflow adapted intracratonic glaciogenic successions. By analysing geomorphology buried basal unconformity, four distinct major ice...

Abstract Glaciogenic reservoirs host important hydrocarbon and groundwater resources across the globe. Their complexity importance for exploration palaeoclimate reconstruction have made glaciogenic successions popular subjects study. In this paper we provide an overview of palaeoclimatic tectonic setting Earth glaciation a chronological account deposits since c. 750 Ma, with particular emphasis on their reservoir potential associated systems. Hydrocarbon accumulations within occur...
Abstract Alluvial fans and fluvial are the most common depositional landforms along margins of continental sedimentary basins. Their occurrence is determined by area, relief hydrology catchment, which ultimately control relative ratios sediment v. flow discharge runoff regimes. Fundamental morphological process distinctions exist between these two kinds deposystem, seen as essentially different facies associations internal architectures for corresponding deposits. commonly develop over short...
The Messinian Qawasim and Abu Madi formations are the main hydrocarbon exploration targets in onshore Nile Delta. Formation constitutes prograditional deltaic system from prodelta distal delta‐front (distal facies) to proximal delta‐plain (proximal facies). sediments on other hand change upward continental subaerial gravity‐flow fluvial facies marginal‐marine estuarine facies. seismic attribute (RMS amplitude) petrophysical analyses revealed that solely define potential reservoir targets....
Abstract A Quaternary interglacial lake sediment record from the Piànico‐Sèllere Basin (northern Italy) consists of biochemical calcite varves with intercalated detrital layers. At end Piànico Interglacial, continuous varve formation was replaced by predominantly sedimentation. However, 427 varve‐years before this shift, an abrupt increase in frequency and thickness layers occurred. Microfacies analyses reveal a total 152 layers, ranging 0·2 to 20·15 mm thickness, deposited during last 896...
Tunnel valleys are elongated incisions formed by meltwater underneath ice sheets that rest on unlithified bed materials. The formation of tunnel is commonly believed to be influenced the properties preglacial bed; however, a detailed analysis this relationship has not been performed date. To determine whether tunnel‐valley location and morphology controlled substratum, 3 D seismic survey was combined with lithological data from W adden S ea area in utch sector southern N orth B asin.
