Sedimentology of the heterolithic and tide-dominated tilje formation (Early Jurassic, Halten Terrace, Offshore Mid-Norway)

Basin-scale architecture of deeply emplaced sill complexes: Jameson Land, East Greenland

“…1a). The Neill Klinter Group is time-equivalent and analogous to the prolific reservoir rocks on the conjugate Halten Terrace offshore Norway (Martinius et al 2001;Ichaso & Dalrymple 2014), and was deposited in a minor sub-basin in the narrow, tide-dominated seaway that occupied the rifted continental crust between present-day Norway and Greenland (Gjelberg et al 1987;Fig. 1a).…”

Time-series analysis of a heterolithic, ripple-laminated deposit (Early Jurassic, Tilje Formation) and implications for reservoir modelling

“…Although loading of the sandstone into the underlying mudstone is present it is not common indicating that the mud had undergone an initial consolidation before the subsequent sand was introduced to the depositional area. The degree of bioturbation varies in the lithofacies and Martinius et al (2001) found that the trace-fossile suite was indicative of a sub-tidal species-rich equilibrium (mixed shallow to mid-tier deposit-feeding and suspension feeding). However, in the further time-series analysis only the least bioturbated intervals of the lithofacies were used since bioturbation makes the measurement of the sandstone and mudstone laminaset thickness unreliable.…”

“…However, in the further time-series analysis only the least bioturbated intervals of the lithofacies were used since bioturbation makes the measurement of the sandstone and mudstone laminaset thickness unreliable. Martinius et al (2001) interpreted this lithofacies to have been deposited in a quiet-water, mud-rich deltafront environment with slow deposition from suspension and sand deposition by traction currents. Tidal influence and possible seasonal variability were assumed to be the main influence on the sedimentation pattern.…”

“…It has previously been shown that low-permeability mudstone layers will have a controlling role on the flow properties at this scale (e.g. Martinius et al, 2001;Yoshida et al, 2004;Ringrose et al, 2005). Nordahl et al (2005) created numerical bedform models at a representative scale for the lithofacies studied here and analysed the single-phase flow performance.…”

“…The formation is very heterolithic and is interpreted to be deposited in a shallow marine setting with varying degrees of tidal influence (Gjelberg et al, 1987;Pedersen et al, 1987;Dreyer, 1992Dreyer, , 1993. More recently, Martinius et al (2001) interpreted the lower part of the formation to have been deposited as storm-dominated shelf and delta-front Marine Geology 235 (2006) 255 -271 www.elsevier.com/locate/margeo overlain by low-relief, incised valleys formed in response to a rapid base-level fall (Fig. 2).…”
