dig-icm-es-10261-2307162022-12-14T09:44:20Z Sedimentary evolution of the Pliocene and Pleistocene Ebro margin, northeastern Spain Alonso, Belén Field, Michael E. Gardner, James V. Maldonado, Andrés Special issue The Ebro Continental Margin, Northwestern Mediterranean Sea.-- 19 pages, 14 figures The Pliocene and Pleistocene deposits of the Spanish Ebro margin overlie a regional unconformity and contain a major disconformity. These unconformities, named Reflector M and Reflector G, mark the bases of two seismic sequences. Except for close to the upper boundary where a few small channel deposits are recognized, the lower sequence lacks channels. The upper sequence contains nine channel-levee complexes as well as base-of-slope aprons that represent the proximal part of the Valencia turbidite system. Diverse geometries and variations in seismic units distinguish shelf, slope, base-of-slope and basin-floor facies. Four events characterize the late Miocene to Pleistocene evolution of the Ebro margin: (a) formation of a paleodrainage system and an extensive erosion-to-depositional surface during the latest Miocene (Messinian), (b) deposition of hemipelagic units during the early Pliocene, (c) development of canyons during the late Pliocene to early Pleistocene, and (d) deposition of slope wedges, channel-levee complexes, and base-of-slope aprons alternating with hemipelagic deposition during the Pleistocene. Sea-level fluctuations influenced the evolution of the sedimentary sequences of the Ebro margin, but the major control was the sediment supply from the Ebro River. © 1990. 2021-02-25T13:00:34Z 2021-02-25T13:00:34Z 1990-12 2021-02-25T13:00:35Z artículo http://purl.org/coar/resource_type/c_6501 issn: 0025-3227 Marine Geology 95(3-4): 313-331 (1990) http://hdl.handle.net/10261/230716 10.1016/0025-3227(90)90122-Z https://doi.org/10.1016/0025-3227(90)90122-Z Sí none Elsevier |
