Abstract

Microtectonic observations have been carried out near the Arzew Mounts (coastal mounts) and in the Tessala and Oulad Ali Mounts (Southern Tell). The structural context is known thanks to previous studies. The result is a polyphased tectonics: a distension period (date Miocene, Late Quaternary), followed by a compressive one (middle Quaternary). Microtectonic analysis and measurings have permitted determinating the shortening direction of the Quaternary compressive phase: it is situated about North150East. This direction is in a accordance whith the lying and kinematics of heterometrical and kilometrical scales quaternary structures.
