Étude sédimentologique et magnétique d’une séquence alluviale du Pléistocène supérieur-Holocène de l’oued Adaila (El Ma Labiod, Tébessa, Algérie) et indications paléoenvironnementales

Abstract: Une étude stratigraphique, sédimentologique et magnétique a été réalisée sur la partie supérieure d'une terrasse alluviale de l'oued Adaila, dans la plaine d'El Ma Labiod (nord-est de l'Algérie). Cette terrasse renferme un niveau très riche en matériel archéologique appartenant à la civilisation atérienne, dont l'âge dépasse 35 000 ans. Du point de vue sédimentologique, les sédiments sont dominés par la fraction limoneuse suivie par les sables fins et grossiers. Du point de vue stratigraphique, la succession d… Show more

“…The peak that is observed around 500 C represents the Hopkinson peak, which is related to the presence of single domain (SD) grains which reside in a superparamagnetic state just before reaching the Curietemperature and have therefore an increased magnetic moment (Collinson, 1983;Zhu et al, 1999); in multidomain (MD) grains this effect is less expressed. The Hopkinson peak was also observed in samples from other sections in this geographic region (Djerrab et al, 2012). However, it cannot be completely excluded that SD grains also formed partially during the measurement, because it is also observed in samples from level 3 (i.e.…”
