ETUDE SEDIMENTOLOGIQUE DES SABLES DUNAIRES DE LA PLAINE DE TAFILALET (Yerdi, Labrouj, Mfis, Merzouga et Lambarkia)

Abstract

The descriptive study of dune facies plain Tafilalet enlightened us on the likely sand sheets, the axis of advance of the sands, and any remobilisassions. Only a more detailed analysis will shed light on the behavior of particles during transport, according to their size or nature of their origin, their specific areas of migration, deposition and remobilization. This characterization of the sand through his elementary particle, will be by laboratory analyzed by granulometric by sieving, morphoscopic by observing the insoluble fraction and mineral by separating the soluble fraction and heavy mineral Identification
