We discuss the main results of a systematic quantitative analysis of the subsidence of the Paris basin made on 100 wells. Backstripping techniques with decompaction as well as sea level and water depth corrections are used to derive tectonic subsidence curves (in the absence of water and sediment loading) assuming local as well as regional compensation.

The Magdalenian in the Paris Basin: New results
Quaternary International, 2012Abstract This paper presents a synthesis of current knowledge on the Magdalenian in the Paris Basin. An inventory of sites and a review of the available radiocarbon dates are used to discuss the peopling of this region over a long period, covering the successive Badegoulian, Middle and Upper Magdalenian cultures.

Cross formational flow in the Paris Basin
Basin Research, 1995AbstractCross formational flow of water has occurred across several hundred metres of Liassic mudstone from the Triassic Chaunoy Formation sandstone to the Middle Jurassic Dogger Formation carbonate in the Paris Basin, France. This has been demonstrated by chemical and isotopic data from rocks and formation waters, sampled on a basin scale, from the ...

The Cretaceous deposits of the Paris Basin
Geological Society, London, Special PublicationsAbstract Since the creation of the Cretaceous system by Jean-Baptiste d'Omalius d'Halloy, numerous analyses have provided details about the Cretaceous sedimentary successions of the Paris Basin, where many boreholes have been drilled. We present a synthesis of the Cretaceous deposits using data from recent drilling carried out in the ...

High Resolution Vibroseis in the Paris Basin
64th EAGE Conference & Exhibition, 2002To image properly the main oil reservoirs in the Paris Basin, a thin carbonate layer (25 m) that lies at 2000 m below the surface, the bandwidth of the signal must be widened beyond 3 octaves (10-80 Hz). During a group shoot acquisition project, the possibilities offered by vibrator control electronics to enlarge the bandwidth and to improve vertical ...

Subsidence analysis in the Paris Basin: a key to Northwest European intracontinental basins?
Basin Research, 1994AbstractDue to the frequently observed disparities between stretching amounts obtained from faults, crustal thickness and tectonic subsidence, the development of intracratonic basins cannot always be explained by a simple model of lithospheric extension.

The Wealden environment: Anglo-Paris Basin
Philosophical Transactions of the Royal Society of London. Series B, Biological Sciences, 1959Abstract The Wealden cyclothems in the Weald are distinct from other sedimentary cycles so far reported. Their re-interpretation is based on recent sedimentological studies of analogous modern environments. The largely arenaceous lower part of each of the two megacyclothems in the Hastings Beds records the several environments of a ...

Origin of the oil-field brines in the Paris basin
Geology, 1990From Br{sup {minus}}/Cl{sup {minus}} ratios coupled with stable-isotope compositions, the components of deep sedimentary brines - namely, primary and secondary brines (from dissolving evaporites) and diluting waters of meteoric origin - can be identified, and in favorable cases, their respective proportions can be quantified. Dilution of primary marine

The Paris Basin is a large intracratonic sag that was formed and filled with sediments during Triassic and Jurassic erustal extensional events that are related, in most parts, to the initial separation of the African and North American continents and the creation of the North Atlantic Ocean (Ziegler 1982; Pages 1987; Figs. 13.1 and 13.2).

The Paris Basin in Magdalenian Times
1987Traditionally, regional tendancies in Paleolithic prehistory have been defined in terms of lithic and bone industries or art. Only recently have attempts been made to perceive cultural entities in Europe through settlement features and economy.
