Paléoécologie et taphonomie comparative en milieux carbonatés peu profonds (oxfordien du Jura suisse et holocène du Belize)

Stienne, Noémie ; Strasser, Andreas (Dir.)

Thèse de doctorat : Université de Fribourg, 2010 ; no 1661.

Sediment on tropical platforms stems from terrigeneous sources and from authigenic carbonate production, and the accumulation is also influenced by lateral migration of sedimentary bodies. The qualitative and quantitative evolution of the sediment flow is controlled by allocyclic and autocyclic processes. The studies of Pittet (1996), Plunkett (1997), Dupraz (1999), Hug (2003), and Védrine...

History of a Middle Berriasian transgression (Switzerland, France, and southern England)

Tresch, Jonas ; Strasser, Andreas (Dir.)

Thèse de doctorat : Université de Fribourg, 2007 ; no 1550.

The aim of this study is to correlate and interpret transgressive deposits of three different depositional regions with high resolution: the marginal-marine carbonates of the Jura platform (France and Switzerland) and the Dorset region (UK). Additionally, a hemipelagic section of the Vocontian basin (France) has been integrated into the high-resolution correlation scheme. The Middle Berriasian...

Carbonate sedimentology, sequence stratigraphy, and cyc-lostratigraphy of the Tithonian in the Swiss and French Jura Mountains : a high-resolution record of changes in sea level and climate

Rameil, Niels ; Strasser, Andreas (Dir.) ; Bosence, Daniel W.J. (Codir.) ; Bläsi, Hansruedi (Codir.)

Thèse de doctorat : Université de Fribourg, 2005 ; Nr. 1493.

The present study aims at a better understanding of the development of the Swiss and French Jura platform during the Jurassic/Cretaceous (J/K) boundary interval, with a special focus on the Tithonian stage. Nine reference sections were measured in the Jura Mountains of northwestern Switzerland and eastern France, in the Helvetic Alps, and in the Subalpine Ranges in south-eastern France. Their...

Paléontologie, paléoécologie et évolution des faciès récifaux de l'Oxfordien Moyen-Supérieur (Jura suisse et français)

Dupraz, Christophe ; Strasser, Andreas (Dir.) ; Berger, Jean-Pierre (Codir.)

Thèse de doctorat : Université de Fribourg, 1999 ; no 1257.

The goal of this study was to determine the factors controlling the settlement and the growth of the coral-dominated reefs in the Oxfordian of the Swiss Jura Mountains, and to analyse how eustatic, climatic and trophic variations are recorded. These reefs developed on a relatively wide and very shallow sub-tropical platform, influenced by periodic siliciclastic input. The coral composition is...

The high-resolution stratigraphic architecture and evolution of the Burdigalian carbonate-siliciclastic sedimentary systems of the Mut Basin, Turkey

Bassant, Philip ; Strasser, Andreas (Dir.)

Thèse de doctorat : Université de Fribourg, 1999 ; no 1256.

The factors influencing the production and deposition of carbonate sediments are known. These are namely accommodation variations (eustasy and tectonics), siliciclastic sediment input, environmental changes (temperature, salinity, trophic level), nature of the producing ecologies, and the hydrodynamic regime. However, the manner in which these factors integrate through time to produce the...

Sédimentologie, stratigraphie séquentielle et cyclostratigraphie du Kimméridgien du Jura suisse et du Bassin vocontien (France) : relations plate-forme - bassin et facteurs déterminants

Colombié, Claude ; Strasser, Andreas (Dir.)

Thèse de doctorat : Université de Fribourg, 2002 ; no 1380.

A detailed sedimentological, sequential and cyclostratigraphic interpretation of the Kimmeridgian in the Swiss Jura defines the principal factors which control the different stages in the development of a shallow-water carbonate platform. A comparative study in the Vocontian Basin reveals their impact on hemipelagic and pelagic sedimentation. The sedimentary facies of three platform sections –...
