Abstract
This work aims to characterize the morphosedimentaty dynamics of the shores of Al-Hoceima Bay through geochemical and mineralogical analysis of surface sediments. The results reveal a direct relationship between marine hydrodynamic forcing on the one hand and detrital inputs from land on the other. Calcimetric analysis makes it possible to highlight the transport and deposition processes at the beaches of Al-Hoceima bay. The difference in the reasonably high carbonate contents in the western beaches (Isli, Cala Bonita and Quemado) (> 60%) and low in the beaches of the central and eastern zone (Sfiha, Souani, Salina and Lharch) (≈ 15%) are mainly due to the influence of coastal currents, littoral drift, and fluvial action. The higher levels of heavy minerals in Lharch beach (18%) are expressed by volcanic outcrops of Cap Quelates and Jbel Tamsamen. The low values at the Souani and Tayth beaches (7% on average) are due to erosion by the two types of coastal drift, NW-SE and NNE-SSW, which carry the sediments of schist origin brought by the Oueds Ghiss and Nekôr. In contrast, the reasonably high contents in the Sfiha beach (12%) are attributed to the accumulation of allochthonous sediments by NW-SE littoral drift which carries sediments of volcanometamorphic origin from Rass Quelates.
Highlights
Soft or sandy Shorelines are fragile and vulnerable spaces where human pressure
The preparation of the scales was carried out following a series of treatments (Wet sieving of the sediments under a net of ordinary water by a sieve of mesh 400 μm embossed in a sieve of 50 μm, the sands are decalcified by hydrochloric acid (HCl) cold hot and Drying in the oven for 24 hours under a temperature of 105°C)
Heavy mineral blades were mounted between blades and slats using Canadian balm on a hot plate to soften the viscous material after a series of treatments
Summary
Soft or sandy Shorelines are fragile and vulnerable spaces where human pressure. Morocco coastal Mediterranean area is the subject of numerous particle size and mineralogical studies of surface sediments, mainly [1], [2], [3], [4], on the bay of Tangier, [5], on Al-Hoceima Bay, and [6], [7], for the Bay of Said. Mineralogical and geochemical analysis of beach sediment identifies the relationship between transport, sedimentation, and sediment condition. The coastal area, especially the beaches of the Ghiss-Nekôr plain and Al Hoceima, have inspired man's action. They have undergone a wide range of facilities and activities, including port facilities, several tourist sites, waterworks on rivers (Abd Elkhatabi Dam on Oued Nekôr) etc. A superficial collection of 33 sand samples was carried out in different parts of the beaches of Al Hoceima Bay on both sides of the oueds, along 17 profiles perpendicular to the shoreline whose objective is to characterize the morpho-sedimentary sediment from the shores of this bay through geochemical and mineralogical analysis of the superficial sediments
