Recent studies carried on in the Carpathian Foredeep [13] demonstrated that such migration can be recorded in the seismic sections as so-called "gas chimneys." One chimney was confirmed by surface geochemical survey by Marzec et al.
Estratos proximales al foredeep de edad Oligoceno--Mioceno temprano, pertenecientes a la Formacion Carbonera, fueron acumuladas durante el crecimiento de estructuras a lo largo del flanco oriental de la Cordillera Oriental (Bayona et al, 2008a; Parra et al, 2009a).
A mediados del Mioceno se experimenta una profundizacion del margen de cuenca (foredeep), debido al proceso de levantamiento de la actual cordillera andina venezolana, lo cual produce un aporte sedimentario proveniente de los bordes de Los Andes colombianos, del escudo de Guayana y del Orogeno Reciente como proceso de reciclaje, teniendo la presencia de petrosomas de sub arcosa litica (Formacion La Rosa) y litarenita feldespatica (Formacion Lagunillas); luego, debido al aumento en las pulsaciones tectonicas relacionadas con el levantamiento andino, se incrementan las acumulaciones de petrosomas tipo grauvacas liticas y feldespaticas, caracteristicas de las formaciones Isnotuy Betijoque.
