Lower Devonian – Depositional Model, Reggane Basin, Southwestern Algeria

P401 LOWER DEVONIAN: DEPOSITIONAL MODEL. REGGANE BASIN. SOUTHWESTERN ALGERIA. 1 The present study provides an integrated stratigraphy of the Lower Devonian of the southestern Reggane Basin Bled El Mass. This is important to establish a standard section allowing an interregional correlation as well as an interpretation of single environmental conditions their changes through time and their geographical extent. Numerous sections have been investigated in this area in addition to data from other profiles in the basin. Investigation of the sedimentary sequence is based on a analysis of events. Initially many events are diachronous whereas others are difficult to define and
