  • The Long-Term Evolution of the Congo Deep-Sea Fan: a Basin-Wide View of the Interaction Between a Giant Submarine Fan and a Mature Passive Margin (Zaiango Project)
    The Congo deep-sea fan: how far and for how long?

(*) [email protected] (**) [email protected] (†) deceased 1.- Introduction The Congo deep-sea fan is one of the largest submarine fan systems in the world and one of the most important depocentre in the eastern south Atlantic. The present-day fan extends over 1000 km offshore the Congo-Angola continental margin and it is sourced by the Congo River, whose continental drainage area is the second largest in the world (3.7 106 km²) (Droz et al., 1996) (Fig.1). There is a direct connexion between the river’s drainage basin and the deep basin through an impressive submarine canyon, which cuts down about 950 m at the shelf-break and more than 1300 m at 100 km offshore the coastline (Babonneau et al., 2002). Hence, the direct transfer of terrigenous material onto the abyssal plain takes place through the canyon, by-passing the shelf and upper slope. The submarine fan covers a surface of about 300,000 km² and contains at least 0.7 Mkm³ of Tertiary sediments (Anka and Séranne, 2004; Droz et al., 2003; Savoye et al., 2000).

    ARTICLE IN PRESS Journal of African Earth Sciences xxx (2005) xxx–xxx www.elsevier.com/locate/jafrearsci South Atlantic continental margins of Africa: A comparison of the tectonic vs climate interplay on the evolution of equatorial west Africa and SW Africa margins Michel Se´ranne *, Zahie Anka UMR 5573 Dynamique de la Lithosphe`re, CNRS/Universite´ Montpellier 2, 34095 Montpellier cedex 05, France Received 5 February 2005; accepted 18 July 2005 Abstract Africa displays a variety of continental margin structures, tectonic styles and sedimentary records. The comparative review of two representative segments: the equatorial western Africa and the SW Africa margins, helps in analysing the main controlling factors on the development of these margins. Early Cretaceous active rifting south of the Walvis Ridge resulted in the formation of the SW Africa volcanic margin that displays thick and wide intermediate igneous crust, adjacent to a thick unstretched continental crust. The non-vol- canic mode of rifting north of the Walvis ridge, led to the formation of the equatorial western Africa margin, characterised by a wide zone of crustal stretching and thinning, and thick, extensive, syn-rift basins. Contrasting lithologies of the early post-rift (salt vs shale) determined the style of gravitational deformation, whilst periods of activity of the decollements were controlled by sedimentation rates. Regressive erosion across the prominent shoulder uplift of SW Africa accounts for high clastic sedimentation rate during Late Creta- ceous to Eocene, while dominant carbonate production on equatorial western Africa shelf suggests very little erosion of a low hinterland. The early Oligocene long-term climate change had contrasted response in both margins.

  • Sea Experience in Developing Countries
    Chapter 6 SEA EXPERIENCE IN DEVELOPING COUNTRIES Increasingly, developing countries are experimenting with SEA and some have SEA-type approaches and elements in place already. There is also considerable experience with using a variety of strategic planning processes that display many of the characteristics of SEA (para SEA). We focus first on SEA in southern Africa where a dedicated regional workshop on SEA was organised to feed into this review (SAIEA 2003a), followed by sections covering francophone Africa, the rest of sub-Saharan Africa, Latin America, Asia and elsewhere. But our survey of this field represents no more than a preliminary reconnaissance. Selected examples of SEA and para SEA illustrate some of the indigenous approaches that have been adopted. These are less common than SEAs promoted and funded by development assistance agencies (which are reviewed in Chapter 4). In most cases where formal SEA has been undertaken in developing countries, the basic aim and approach has mirrored that in the north – namely to identify the environmental consequences (and associated social and economic effects) of existing, new or revised policies, plans and programmes. These represent only a small number of the broad family of SEA approaches. But they are a highly visible sub-set of the large suite of informal or para-SEAs which form part of development policy-making, land use planning or resource management. No strict boundaries can be drawn for this latter area of application. Only the more evident SEA type elements and approaches are introduced in this chapter. Nevertheless, they indicate the scope and diversity of the extended SEA family in developing countries, where political and economic realities constrain what can be done.

  • Hafnium and Neodymium Isotopes in Surface Waters of the Eastern Atlantic Ocean: Implications for Sources and Inputs of Trace Metals to the Ocean

These data are complemented by Hf and Nd isotopic and con- centration data, as well as rare earth element (REE) concentrations, in Saharan dust. Hafnium concentrations range between a maximum of 0.52 pmol/kg in the area of the Canary Islands and a minimum value of 0.08 pmol/kg in the southern Angola Basin. Neodymium concentrations also show a local maximum in the area of the Canary Islands (26 pmol/kg) but are even higher between ~20°N and ~4°N reaching maximum concentrations of 35 pmol/kg. These elevated concentrations provide evidence of inputs from weathering of the Canary Islands and from the partial dissolution of dust from the Sahara/Sahel region.

However, many of the governments tend to be ad hoc in their planning and, as a result, EIA is often regarded as an ‘add on’ process “that gets done ‘later on’, after the government, board of directors or other body has decided that the intended initiative is viable and thus worthy of detailed planning” (Tarr, 2003). In recent years, there has been rapid progress in the formulation of policies, legislation and guidelines for EIA (SAIEA 2003b).

In both upper U-Pb zircon geochronology and lowermost parts of the catchment, tributaries contain significant amounts of feldspars, rock fragments, or Zircon weatherability moderately stable heavy minerals pointing at the central basin as the main location of the “quartz factory”.

    Acta Geologica Polonica, Vol. 48 (1998), No. 1, pp. 43-106 Facies, stratigraphy and diagenesis of Middle Devonian reef- and mud-mounds in the Mader (eastern Anti-Atlas, Morocco)1 BERND KAUFMANN Institut für Geologie und Paläontologie der Universität Tübingen, Sigwartstr. 10, D-72076 Tübingen, Germany. E-mail: [email protected] ABSTRACT: KAUFMANN, B. 1998. Facies, stratigraphy and diagenesis of Middle Devonian reef- and mud-mounds in the Mader (eastern Anti-Atlas, Morocco). Acta Geol. Polon., 48 (1), 43-106. Warszawa. During the Devonian, the eastern Anti-Atlas formed a part of the northwestern continental margin of Gondwana which was a mid-latitudinal (30-40°S), temperate-water carbonate province. In the Mader region, ten carbonate mounds (one reef-mound and nine mud-mounds), distributed over five discrete localities, are intercalated within a 200-400 m thick Middle Devonian succession. The arid climate of the northwestern margin of the Sahara has exhumed these mounds which display perfectly their origi- nal morphologies and relations to off-mound lithologies. The carbonate mounds of the Mader area consist of massive, stromatactis-bearing boundstones (wackestones and floatstones in a purely descriptive manner) with the bulk of the mound volume con- sisting of fine-grained carbonate (microspar). High accumulation rates (0.2-0.8 m/1000 a), purity of mound carbonates (> 95% CaCO3) and homogeneous Mg-calcite mineralogy strongly argue for in situ carbonate production by microbial (cyanobacterial/bacterial) communities. In addition, other indica- tions (calcified cyanobacteria in the immediate neighbourhood of stromatactis fabrics, dark crusts sur- rounding stromatactis fabrics and alignment of stromatactis fabrics parallel to the accretionary mound surfaces) suggest a close relationship between stromatactis formation and carbonate production.

  • Deep Sea Drilling Project Initial Reports Volume 74
    9. CRETACEOUS-TERTIARY PLANKTONIC FORAMINIFERS FROM THE SOUTHEASTERN ATLANTIC, WALVIS RIDGE AREA, DEEP SEA DRILLING PROJECT LEG 741 Anne Boersma, Microclimates, Inc., Box 404, RR 1, Stony Point, New York ABSTRACT Planktonic foraminifers were studied from the > 149 µm fractions of Cretaceous and Cenozoic sediments at DSDP Sites 525, 526, 527, 528, and 529, all clustered in the southernmost Angola Basin and central Walvis Ridge area of the southeastern Atlantic. Faunas were commonly mixed by consistent slumping in the Maestrichtian and, to a lesser de- gree, in the Paleocene. Contamination that is presumed to be due to downhole coring emplacement of coarse-fraction drilling sands was common in thte Miocene of Sites 525 and 528, particularly in the mid-Miocene (Zones NI 1-N13). Spe- cies ranges presumed to be anomalous in these intervals, therefore, are frequent. Cretaceous sediments were interlayered with basalt and/or altered by contact with basalt at all but Site 529. Incon- sistency between foraminiferal and nannofossil zonations and paleomagnetic results through most of the Maestrichtian at all sites is attributed to consistent slumping of sediment coarse fractions, which include most of the foraminifers. Paleocene sediments are moderately well preserved at Sites 525, 527, 528, and 529, but the sections are incomplete. Only shallow-water carbonates with some larger foraminifers were attributed to the Paleocene (Manivit, this volume) in Hole 526C. At three sites, 525, 527, and 528, good, apparently continuous Paleocene/Eocene boundary sections were recovered. The Eocene was recovered at all sites, but is incomplete because of dissolution near the CCD at Sites 528 and 527, typical South Atlantic mid to late Eocene dissolution and recrystallization at Sites 525 and 529, and lack of index fossils in the shallow-water carbonates at Site 526.
