The book "Deep-Sea Sediments" focuses on the sedimentary processes operating within the various modern and ancient deep-sea environments. The individual chapters track the way of sedimentary particles from continental erosion or production in the marine realm, to transport into the deep sea, to final deposition on the sea floor. The sedimentary processes cover several types of sediment gravity flow and contour currents, pelagic settling and hemipelagic advection, planktic and benthic bioproductivity, and volcanoclastic sedimentation. In addition, the relationships between depositional environment and endobenthic organisms, as well as early diagenetic processes at and within the deep-sea floor are dealt with. Facies models of the wide range of depositional products hold the key for a process-related interpretation of ancient deposits. Changes in sea-water chemistry, major innovations in organism evolution, and changes in external controls on sedimentation and productivity are discussed in the context of overarching trends in ocean history. Deep-sea sediments are not only of interest because of the numerous interacting processes involved in their formation, but they represent also a nearly inexhaustible archive of long-term climatic changes. Consequently, the book also includes an introduction to the climatic interpretation of the various proxies that reveal global changes during the Mesozoic greenhouse and Neogene icehouse conditions. In order to address the specific interest of the oil and gas industry in deep-water sediments, the investigation techniques that are applied in this context and the methods to predict both the occurrences and the characteristics of hydrocarbon reservoirs, are included as well. This title examines the rapidly evolving field of deep-sea sedimentary research. It focuses on sedimentary and diagenetic processes, with theory and case histories. It covers the climate record, hydrocarbon reservoirs, and other topics of interest. It features a multimedia component with colour versions of figures.

Jørgensen and Boetius (2007) define the seafloor as the top meter layer of the seabed that is bioturbated by animals and porous ocean crust that is penetrated by seawater, whereas the deep subsurface, which harbors the deep biosphere, comprises the sediment and rock that is deeper than 1 m below the seafloor (mbsf).

The result of the intermittent accumulation of sediment are thin and condensed successions with abundant hiatuses. Such bottom‐current deposits are poorly known, since the broadly accepted contourite‐facies model, the bi‐gradational sequence, characterizes environments of contourite depositional systems as a continuous accretion of fine‐grained siliciclastic sediments. To increase current understanding of the carbonate facies within hiatal contourite records, the Eifelian–Frasnian of the Tafilalt Platform in Morocco was investigated. The succession is divided into five facies associations that are interpreted to reflect pelagic sedimentation and deposition from bottom currents on a contourite terrace, a gently inclined section of the upper slope of Gondwana shaped by a water‐mass interface. Contourite depos...

The investigated sites display up to 30 m thick sequences of glacial tills with intercalated (glaci)fluvial to (glaci)lacustrine sediments. Based on detailed lithofacies analyses and a physical age chronology, we trace the reconstruction of the depositional sequences and their corresponding stratigraphic position within the Weichselian record.

The Skoura region at the southern foot of the High Atlas includes a west-east, discontinuous sequence of Devonian and Lower Carboniferous outcrops, from Tizi-n´Tichka East in the NW of Ouarzazate to Asserhmo in the NE. Based on detailed logging, microfacies, conodont and macrofauna sampling, especially at Taliouine and Tizi n-Ouourti, the regional Devonian litho, bio- and event stratigraphy and facies development is revised. The Lochkovian is marked by a change from unfossiliferous black shales (Lower Member of new Tizi-n-Tichka Formation) to condensed, discontinuous, black, detrital Orthocone Limestones (Upper Member, middle Lochkovian) deposited under strong bottom current influence (contourites). Slumps and a subsequent erosional disconformity mark the regional tectonic episode Sk-TP-1a, followed by a distinctive "Antevariscan" conglomerate and reworking...

La coupe de Klausberg presente une des lentilles isolees des calcaires hercyniens qui affleurent dans la zone de Harzgerode des monts inferieurs du Harz. Ces lentilles sont de type phacoide. En outre, la texture lithologique des schistes correspondants et la stratification chaotique des grands blocs de calcaire entre eux, ainsi que dans les parties marginales de ces blocs eux-memes, montrent des signes evidents de mouvements de transport en masse. Une reconstruction synoptique de la sequence carbonatee des calcaires hercyniens permet des conclusions sur l'histoire dynamique de leur region de sedimentation primitive. Le facies du Devonien qui reflete un approfondissement par saccades de la region de sedimentation primitive est compatible avec les sequences sedimentaires qui illustrent l'enfouissement des plates-formes de carbonates. La coupe de Klausberg represente une seq...
