Resumen

La Formación Santa Cruz consiste en una sucesión de sedimentos continentales del Mioceno Temprano–Medio que se encuentran ampliamente distribuidos en la Patagonia austral. Se describen los atributos sedimentológicos y estratigráficos de tres localidades a lo largo del Río Santa Cruz. De este a oeste estas localidades son: Barrancas Blancas, Segundas Barrancas Blancas y Yaten Huageno. El análisis de facies permitió definir tres Asociaciones que representan acumulación en 1) planicies de inundación; 2) lóbulos de desbordamiento y crecidas en manto; y 3) canales fluviales. Las tres localidades son cronológicamente equivalentes y representan acumulación en un sistema fluvial de bajo gradiente con alta agradación, el cual drenaba hacia el este y noreste desde los Andes Patagónicos hasta la plataforma. Los rasgos de los paleosuelos, más algunas trazas fósiles reconocidas, sugieren un clima templado subhúmedo y en parte, una planicie herbácea.
