Abstract

Well data from the Cambrian to Silurian succession of the Illizi Basin, Algeria, were interpreted to derive a depositional model and correlate the wells in a sequence stratigraphic framework. The succession contains thick glacimarine deposits of the Late Ordovician glaciation. The preglacial deposits show a retrogradational stacking pattern of terrestrial and shallow marine deposits. The synglacial succession is dominated by subaqueous fan deposits. Glacimarine depositional sequences were controlled by advance and retreat cycles of the glacier. Two glacial advance and retreat can be correlated across the study area. The postglacial succession was deposited on the shelf, infilling the residual glacial topography.
