Spatial Distribution of Beach Sediments between Grand-Lahou and Jacqueville (Cote dIvoire): Granulometric and Mineralogical Approach

This work is a contribution under investigation heavy and light minerals of the sandy sediments of the littoral perimeter of Grand-Lahou and that of Jacqueville. It also relates to the granulometric distribution of sandy sediments taken on these beaches. The heavy minerals are composed in majority by ilmenite and the rutile in all the samples taken on the beach of Grand -Lahou. The other mineralogical species met play a secondary part in the composition of the heavy mineral processions. They are in particular, the chlorite, epidote, garnet, pyroxene, the rutile, sillimanite and the sphene. The light minerals are primarily made up of grains of quartz with hyaline aspect or translucent and of the grains with milky aspect. Among light minerals, one also recognizes the feldspars which are slightly represented in these samples. On the beach of Jacqueville one notes the presence of quartz, feldspaths, sillimanite, biotite, pyroxene, ilmenite and amphibole. Whatever their source, sands contain minerals at various stages of deterioration. The mineralogical procession is influenced by the geological nature of the area
