Activity of the turbidite levees of the Celtic–Armorican margin (Bay of Biscay) during the last 30,000 years: Imprints of the last European deglaciation and Heinrich events
High-resolution sedimentological and micropaleontological studies of several deep-sea cores retrieved from the levees of the Celtic and Armorican turbidite systems (Bay of Biscay — North Atlantic Ocean) allow the detection of the major oscillations of the British–Irish Ice Sheet (BIIS) and ‘Fleuve Manche’ palaeoriver discharges over the last 30,000 years, which were mainly triggered by climate ...

متن کاملExternal Controls on Modern Clastic Turbidite Systems: Three Case Studies External Controls on Modern Clastic Turbidite Systems: Three Case Studies
Three case studies are used to exemplify the wide variety of controlling factors that combine to influence the development of modern turbidite systems, and how these vary with location and time. For example, Cascadia Basin in the Pacific Ocean off western North America, which is underlain by the Cascadia Subduction Zone, exhibits the dominant tectonic control of earthquake triggering for turbid...
متن کاملGreat earthquakes along the Western United States continental margin: implications for hazards, stratigraphy and turbidite lithology
We summarize the importance of great earthquakes (Mw & 8) for hazards, stratigraphy of basin floors, and turbidite lithology along the active tectonic continental margins of the Cascadia subduction zone and the northern San Andreas Transform Fault by utilizing studies of swath bathymetry visual core descriptions, grain size analysis, Xray radiographs and physical properties. Recurrence times of...
متن کاملSouth Armorican Shear Zone and Continental Fit before the Opening of the Bay of Biscay
Geological similarity between Hercynian zones from Brittany and the Iberian Peninsula has led various authors [l-31 to propose that these zones were once continuous. Bard et ai. [3], for example, reconstmct the Hercynian 1bero.Armorican belt to find the position of the Iberian peninsula before the opening of the Bay of Biscay (1 50 to 200 my ago). They assume continuity of Hercynian structures ...
