| Critical speeds for erosion, transport and deposition of sedimentary particles and prevailing bottom currents intensities are in such a range that the textural properties of the sediment silt fraction may be correlated to the intensity of the deep circulation. On the other hand, the long axis of the sediment magnetic susceptibility ellipsoid, should be aligned according to the current flow. These hypotheses have been positively tested in five abyssal areas. The authors then apply textural studies to the study of Cenozoic deep water circulation in two continental margin areas (Bay of Biscay and Western mediterranean, DSDP Site 400 and Site 372). The results are in good agreement with informations provided by micropaleontological and geochemical... |
