Abstract

During the marine sedimentation within the Togo coastal basin, the impact of input continental origin was very important despite their various nature and the sedimentary or diagenetic modifications demanded by active or passive receptive depositional environment. Sedimentary clays in the basin reflect climatic, tectonic and morphological evolution from the late Cretaceous through Tertiary: erosion, weathering, margins stabilisation, pedogenesis and basin subsidence. Key words: Clay mineral, sedimentation, coastal basin, Togo Maastrichtian, Palaeocene, Eocene, margin, subsidence, climate, trangression. Resume Tout au long de la sedimentation marine dans le bassin cotier du Togo, l\'impact des apports d\'origine continentale a toujours ete important, malgre leur nature variable et les modifications sedimentaires et diagenetiques imposees par le milieu recepteur actif ou passif. Les argiles sedimentaires du bassin refletent l\'evolution climatique, tectonique et morphologique du Cretace-Tertiare: erosion, alteration, stabilisation des marges, developpement des pedogeneses et subsidence du bassin. Mots cles: Argile minerale, sedimentation, bassin cotier, Togo Maastrichtien, Paleocene, Eocene, marge, subsidence, climat, transgression. (Af. J. of Science and Technology: 2002 3(2): 96-100)
