• Resumen

  • The Scala Dei Croup, which is composed mainly of conglomerates, is located in the SE sector of the Ebro Basin. Many alluvial fans were developed in this area during the Eocene-Oligocene time span. The clastic materials were transported and accumulated by hydraulic currents in braided-style rivers. However, there is a conglomeratic lithosome with a characteristic medium angle cross bedding continuous from the basal scar up to the medial part of the body. This is interpreted as a deposited in a sinuous channel with characteristics of coarse-grained meandering, and represents an important variation in depositional style. These variations can be associated with the a real shifting of the technically active basin border
