Sedimentary provenance analysis of the ordovician to devonian siliciclastic units of the Subandean Ranges and Santa Barbara System, northwestern Argentina

This paper explores the sedimentary provenance of the Ordovician to Devonian siliciclastic sequences of the Subandean Ranges and Santa Barbara System in the northwest (NW) of Argentina. We performed a comprehensive sediment provenance analysis of the Zapla Formation (upper Ordovician), Lipeón Formation (Ordovician–Silurian) and Arroyo Colorado Formation (Devonian) from the Zapla, Puesto Viejo and Unchimé ranges, using sedimentological...
