Abstract

MESTRE, Ana  and  HEREDIA, Susana. The lower paleozoic in the eastern flank of the sierra de pedernal, cienaguita, eastern precordillera. Ser. correl. geol. [online]. 2014, vol.30, n.1, pp.5-12. ISSN 1666-9479.

In the eastern fank of the Pedernal hill the Lower Paleozoic stratigraphy is complex and affected by an intense deformation. This paper describes a new section where relicts of Los Azules and Don Braulio formations are recognized for the frst time; these units are overlapping the San Juan Formation and above the La Rinconada For-mation are recorded. This fnding allows extending the paleographic distribution of darriwilian and hirnantian basins southward of the San Juan River at least until this region of the Eastern Precordillera.

Keywords : Paleozoic; Stratigraphy; Cienaguita; Eastern Precordillera.
