          Abstract

          La Formación Yegua (Eoceno) en la Cuenca de Burgos se divide en tres unidades. La unidad Yegua inferior es arenisca de ambiente litoral y, bajo un análisis de secuencias, representa una etapa de nivel alto, cuya cima es cortada por una superficie de discordancia o límite de secuencia regional. Esta superficie de discordancia marca un límite de secuencia de alrededor de 39.5 Ma. La unidad Yegua intermedia es una facies compleja; consiste en areniscas de abanicos de piso, canales y discordancias internas, que corresponden a un sistema de depósito bipartito compuesto por una fase de nivel bajo y una cuña progradante, además de una fase de transgresión. La unidad Yegua superior corresponde a una etapa de nivel alto y subyace a una facies de inundación que pertenece a la base de la Formación Jackson. La Formación Yegua posiblemente refleja el acarreo final de sedimento hacia el Golfo de México ancestral como resultado del levantamiento y deformación orogénica de Laramide, en el noreste de México.

          The Yegua Formation (Eocene) in the Burgos Basin is divided into three units. The lower Yegua is sandstone deposited in a near shore environment of a highstand systems tract (HST), whose top is truncated by a prominent unconformity and regional sequence boundary at around 39.5 Ma. The middle Yegua is a complex facies, which consists of basin-floor fan sandstones, channels, and unconformities corresponding to a lowstand systems tract and prograding wedge, but also includes a transgressive systems tract. The upper Yegua represents a HST, which underlies the maximum flood surface that constitutes the base of the Jackson Formation. The Yegua Formation possibly reflects the final sediment influx towards the ancestral Gulf of Mexico resulting from Laramide age uplift and orogenic deformation in Northeastern Mexico.
