“…The Lower Cretaceous succession extends into the Eastern Cordillera, where the sediments were deposited in an extensional context and are restricted to the western side of the basin by the Guaycaramo Fault System (a structure that corresponds to the former boundary of the Early Cretaceous depocentre). These deposits are absent in the Llanos Foreland (Villamil 1999;Bayona et al 2006;Sarmiento-Rojas et al 2006).…”

“…The geochemical composition of connate waters in the LBC could indicate a nonmarine Tertiary origin (Cooper et al 1995;Villamil 1999;Bayona et al 2006;Hoorn et al 2010). The fluvial and fluvio-deltaic sedimentary environments of the Mirador and Carbonera fms imply an initial supply of bicarbonate fresh water to the system.…”

“…Paleogeographic reconstruction of the Cenozoic strata in Colombia shows that the lower Eocene strata of the Mirador Formation are dominated by sandy fluvial facies and that the middle -upper Eocene is dominated by mudstones and sandstones that accumulated along a NNE-elongated fluvial system with periods of marine ingression (Reyes-Harker et al, 2015;Santos et al, 2008). This late Eocene depositional configuration continued in the Oligocene with the accumulation of mudstones of the C8 Member of the Carbonera Formation to the west and coeval sandstone deposits to the east; these sandstones predominate along the eastern border of the southern Llanos Basin and are called Oligocene basal sandstones or basal sandstones of the Carbonera Formation (Malagón, 1997;Bayona et al, 2006).…”

“…Esta región se encontraba principalmente dominado por sistemas fluviales y lacustres de ambientes semi-áridos que progresivamente pasaban a ambientes lacustres y pantanosos de humedales de clima húmedo (Hoorn et al, 2010). A partir del registro de polen de manglares y foraminíferos, diversos autores confirman la existencia de una ingresión marina para este intervalo dentro de las formaciones de Pebas y Carbonera (Cuenca de Llanos), que afectaron una amplia extensión a pesar de su corta duración (Hoorn 1993a(Hoorn , 1994aBayona et al, 2007b).…”
