Abstract
Up-to-date lithostratigraphic
classifications of the Triassic detritals of the Upper Triassic
and Lower Jurassic evaporitic series have been made in
North-Central AIgeria. It is believed that the formation of the
Lower Triassic fluvio-deltaic deposits and the principal Upper
Trias-Lias evaporites may be explained in terms of plate
tectonics. Correlation of the Triassic formations were found
possible between the two different tectonic units known in
Algeria. The Epihercynian and Pre-cambrian platforms attained
their main tectonic features after the Early Alpine
"Post-Liassic" orogenic movements; whereas the
successive southerly migrations of the Equator during Later
Triassic time led to the formation of several lagoons.
