dc.description.abstractThe Baza basin is a large Neogene intramontane basin in the Bétic Cordillera of southern Spain that formed during the Tortonian (late Miocene). The Bétic Cordillera was produced by NW–SE oblique convergence between the Eurasian and African Plates. Three seismic reflection lines (each 18 km long; vibroseis method) were acquired across the Baza basin to reveal the architecture of the sedimentary infill and faulting during basin formation. We applied rather conventional CDP data processing followed by first arrival P-wave tomography to provide complementary structural information and establish velocity models for the post-stack migration. These images show a highly asymmetric structure for the Basin with sediments thickening westward, reaching a maximum observed thickness of > 2200 m near the governing Baza Fault zone (BFZ). Three major seismic units (including several subunits) on top of the acoustic basement could be identified. We use stratigraphic information from the uplifted block of the BFZ and other outcrops at the basin edges together with available information from neighboring Bétic basins to tentatively correlate the seismic units to the known stratigraphy in the area. Until new drilling or surface outcrop data is not available, this interpretation is preliminary. The seismic units could be associated to Tortonian marine deposits, and latest Miocene to Pleistocene continental fluvio-lacustrine sediments. Individual strands of the BFZ truncate the basin sediments. Strong fault reflections imaged in two lines are the product of the large impedance contrast between sedimentary fill and basement. In the central part of the Basin several basement faults document strong deformation related to the early stages of basin formation. Some of these faults can be traced up to the shallowest imaged depth levels indicating activity until recent times. © 2017 Elsevier B.V.es_ES
dc.description.sponsorshipThe project was funded by the German Science Foundation (grant HA3326/2-1) and the GFZ Potsdam. Recording equipment was provided by the Geophysical Instrument Pool (GIPP) of the GFZ (grant GIPP201312). We thank the contractor companies Geofisyka Torun (Poland; vibroseis sources) and GEOLAND (Spain; permitting) for the professional work rendered to the project. Field acquisition was performed by mixed teams from Germany, Spain, Italy, and the U.S.A., and we thank all field crews for their excellent work. Teresa Teixido (Granada) kindly supported the field work. Seismic interpretation was performed at ICTJA-CSIC using Petrel software (Schlumberger).
