    Notes: [Auszug] ALLAN Cox, Professor of Geophysics at Stanford University in California and principal architect of the magnetic polarity reversal timescale, one of the pillars of plate tectonics, died in an accident on 27 January. Shortly before his death he had announced his intention to return to teaching and ...

    Notes: [Auszug] IN a recent paper based on work with a deep-diving research submarine, fine-scale observations of the sea floor are ingeniously extrapolated to models of the events occuring at depth*. The paper is a good example of the geologist's method of using detailed observations on rock outcrops to yield ...

    Notes: [Auszug] The collection from the upper slope (Dredge 2, 2,6702,050 m) consists, as noted1, of fragments of greenstone, basalt, and partly metamorphosed basaltic tuff. The fragments exhibit a thin manganiferous coating, usually on all sides. This observation and the angularity of the fragments suggest that ...

    Notes: [Auszug] No more than a quarter-century ago we knew little about the deposits beneath the ocean floors, and less concerning the history of the two-thirds of the world which they occupy. Since then the new discipline of palaeoceanography has come into being, and has quickly illuminated a remarkable variety ...

    Notes: [Auszug] FOR more than a century geologists have felt comfortable with the notion that geological processes, although very slow, are also steady and so capable of moulding the Earth given enough time. The steady drip hollows the stone. The idea of steadiness came, at least in part, in reaction to the ...

    Notes: [Auszug] From -9,000 to 8,000 yr BP the inhabitants collected mainly Cyclope neritea2, a small (-15 mm) species which lives in the littoral zone near the mud surface and also flourishes in brackish water. It is gregarious and a carnivore. Although small it is easy to catch because it occurs in large numbers ...

    Description: This study is based on a reconstruction of the paleogeographic and paleobathymetric history of the South Atlantic and on a standardized set of sediment and biostratigraphic data from all Deep Sea Drilling Project sites. Standard data sets used are the lithologic description, biostratigraphic age, CaCO3 content, carbonate and carbonate-free sedimentation rates corrected for compaction, and hiatus distribution. For each site the subsidence history has been determined. Paleoceanographic variables used are the spatial and temporal lithofacies distribution, history of calcite compensation depth, surface fertility and lyocline, erosional events, and special lithologies (black shales). During its early history the South Atlantic consisted of a narrow rift divided by the Rio Grande Rise- Walvis Ridge barrier into a restricted northern and an open (to the southern ocean) southern basin. In the northern basin, evaporites are the earliest known marine sediments (Aptian) while more normal pelagic deposits formed in the southern basin. Free circulation of surface water between the southern ocean and the North Atlantic became possible late in the Mesozoic or in the early Cenozoic, and deep circulation (below 3 km depth) paths were open from north to south by the early Cenozoic. During the early and middle Mesozoic the South Atlantic had its own oceanographic character with dominantly terrigenous sedimentation and two anoxic black mudstone phases (Albian and Santonian) probably resulting from a strong oxygen minimum in mid-water caused by either excess surface fertility or old, slow moving bottom water. In the late Cretaceous the South Atlantic became part of the world ocean system and global events have overshadowed local ones since that time. After the early phase of rapid sedimentation of terrigenous material, the depositional history has been in- fluenced mainly by the increasing width and water depth of the basin and by fluctuations of the level and intensity of carbonate dissolution. At the Eocene/Oligocene boundary, the onset of a deep water circulation dominated by a cold circum-polar source of surface water is clearly marked by erosional events, a sharp drop of the calcite compensation depth and the arrival of biogenic siliceous oozes in the Argentine Basin.
