Download e-book for iPad: Geology of the Northwest African Continental Margin by U.v. Rad, K. Hinz, M. Sarnthein, E. Seibold

The Northwest African and the conjugate Northeast American continental margins offer first-class examples of mature passive continental margins which list of their thick sediment hide the beginning and evolution of the Atlantic Ocean Basins in the past 2 hundred million years. because of a dense internet of unmarried- and multichannel seismic mirrored image traces, quite a few Deep Sea Drilling undertaking (DSDP) websites and petroleum exploration wells, and
the recognized onshore geology, the Northwest African margin is among the bes"t-documen ted margins of the realm. a selected good thing about this margin is that its coastal basins are good uncovered and available for targeted stratigraphic reports and onshore-offshore correlations, while the Mesozoic-Cenozoic marginal basins off jap North the United States underlie only
the current continental shelf and slope.

Beaches in the exponential category had the narrowest beachface (13–18 m), whereas those in the convex-curvilinear group were widest (36 –53 m) for all sites (Table 2). Dimensions of the sub-tidal terrace also varied between profile groups and between study sites. 388). Modal sediment size also varied between profile sites for each study environment. 5 mm), with coarsest sediment associated with sites in the vicinity of Hanover Bay and finer grains characterizing beaches in Shoal Bay in the SE of the Harbour.

In accordance with variation in the wind regime, wave climate varied systematically around Cockburn Sound with aspect and exposure. The most energetic conditions for all fetch directions occurred in the SW around Rockingham, followed by Buchanan Bay and Sulphur Bay. The least energetic conditions for all key wind characteristics under consideration occurred at Mangles Bay on Garden Island. In keeping with results from Albany, attenuation of wave height by the sub-tidal terrace accentuated the disparity between highest and lowest wave sites, with Mangles Bay, with a long, low subtidal terrace, experiencing the greatest reduction in wave height and Rockingham the least.
