These studies show that the basins formed and were filled while being carried on moving thrust sheets, and they are therefore named piggyback basins. Each of these basins corresponds to the active phase of a different thrust-front ramp. On the Pyrenean (northern) margin of the Ebro basin complex, northern Spain, similar piggyback basins formed between Eocene and mid-Miocene time. They have since been uplifted and eroded and may therefore be studied in outcrop. In northern Spain, much of the basin-fill sediment was deposited in nonmarine environments. This content is PDF only.
