Abstract:

Detailed mineralogical and geochemical studies were performed on samples from selected time intervals recovered during Leg 79 on the Mazagan Plateau. The uppermost Albian and Cenomanian sediments of Sites 545 and 547 can be correlated on the basis of mineralogy and geochemistry; these sediments illustrate differential settling processes and the existence of hot climates with alternating humid and dry seasons in the African coastal zone. The upper Aptian to Albian black shales of Site 545 point to an irregular alternation of tectonic activity and relaxation stages, allowing different behaviors in the reworking of soils, crystalline rocks, and sediments born in peri-marine basins. The barren lower Mesozoic reddish sediments and evaporitic series of Sites 546 and 547 are characterized by a strong physical erosion of sialic landscapes, without clear evidence of post-depositional metamorphic events. At Site 546 strong early diagenetic processes in a confined evaporitic environment affect both the mineralogy and the geochemistry of pre-Miocene rocks.
