The ordovician system in the Argentine Eastern Cordillera

Abstract

The purpose of this chapter is to offer a synthesis on the main geological features of the Ordovician deposits that crop out in the Eastern Cordillera (Cordillera Oriental) of northwestern Argentina. The regional and interregional geological framework that controlled the Ordovician sedimentation is considered by following previous works (Moya, 1999a, 2002), and including recent observations referred to the localities or sections to visit.
