Stratigraphy
| Formation: | Ituzaingo | Member: | Conglomerado Osifero | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: The fluvial Ituzaingo Formation overlies the marine unit. This formation is composed of a basal conglomerate (“Conglomerado osifero”) with abundant vertebrate remains which is overlain by almost unfossiliferous whitish to yellow brown sandstones and green mudstones. Terrigenous Pleistocene (Ensenadan to Lujanian in the southern South American continental scale; see Cione and Tonni, 1995, 1996, 2001; Fig. 2), poorly fossiliferous beds assigned to different units overlay the Ituzaingo Formation (Aceñolaza, 1976; Iriondo, 1980; Chebli et al., 1989). The Ituzaingo Formation (as Entre Rios Formation) was correlated with the “Formacio ́n Puelche” of the Buenos Aires province subsoil (Reig, 1957; see below). According to the mammals occurring in the “Conglomerado osifero” and the stratigraphic relationships, the age of the base of Ituzaingo Formation is almost exclusively Tortonian (late Miocene) or Huayquerian in the local chronology (Pascual and Odreman Rivas, 1971; Cione and Tonni, 1995; Fig.2).
