Sedimentary stratigraphy of eocene sheetflood deposits, Southern Pyrenees, Spain

Material type: ArticleDescription: 167-183pp ; Illustration.Subject(s): Sedimentary stratigraphy | Eocene sheet flood deposit | Ager formation | Fluvial environment | Monolbbat formation | Castisnet formation In: Geological magazine : Vol. 123 Iss. 1-6 Year. 1986Summary: The Eocene Monllobat Formation of the southern Pyrenees accumulated under continental (non-marine) conditions. The total thickness of 180 m consists of seven cycles, defined by coarse member concentrations (often sheets) at the bases. The lateral extent of the sheets defines the fixed positions of eight parallel-trending alluvial systems, separated by narrow zones of fine sediment. Sheetflooding dominated the sedimentation of these eight contemporaneous alluvial systems. The sediment was supplied from the rising axial zone of the Pyrenees. The cycles were caused by variations in tectonic activity. The positions and forms of coarse members were locally determined by contemporaneous faulting and folding of the alluvium.Item type | Current location | Collection | Call number | Status | Date due | Barcode |
