摘要: The Cretaceous north Pyrenean interplate basin developed in conjunction with the opening of Bay Biscay deposition large amounts carbonates on its margins. Major failures linear segments shelf and slope generated autosuspended mass flows; some these flows differentiated orevolved into megaturbidites that are up to 63 m thick 95 km long. A study evolutionary flow-megaturbidites also has application petroleum geology because it can help detail anatomy a related distribution sedimentary bodies paleoenvironments.
