Conference Paper
Full-text available
Located in SE Asia in between the Palawan and the Philippine islands, the lozenge-shaped Sulu Sea corresponds to a marginal sea that displays a complex seafloor morphology. The NE-SW trending Cagayan Ridge separates a southeastern deep-water domain, which is bounded by the Sulu Trench towards the east, from a shallower and narrower northwestern dom...
Conference Paper
Full-text available
The Sulu Sea lays in between Palawan and the Philippine islands. This marginal sea has been considered as part of the Sunda microplate, together with the South China Sea and most of SE Asia and related seas (e.g., Bird et al., 2003). It shows a lozenge morphology and displays a complex bathymetry. The Cagayan Ridge separates a shallower and irregul...
Article
Full-text available
Large uncertainties remain about the architecture, timing and role of the structures responsible for high degrees of crustal thinning and the exhumation of mid-crustal granulites in the Pyrenean and Biscay rift systems. Both, Le Danois High in the North Iberian margin and the Labourd Massif in the Western Pyrenees preserve evidence of extensional d...
Article
Full-text available
The aim of this paper is to provide a conceptual framework that integrates the role of inheritance in the study of rifts, rifted margins and collisional orogens based on the work done in the OROGEN project, which focuses on the Biscay-Pyrenean system. The Biscay-Pyrenean rift system resulted from a complex multistage rift evolution that developed o...
Article
Full-text available
This contribution investigates the role of a hyperextended rift system in the formation of the Basque – Cantabrian Pyrenees by discussing their present‐day architecture as well as the inherited rift template. Moreover, this work attempts to decipher the onset of reactivation of a hyperextended system and to discuss the related processes during coll...
Article
Crustal roots are identified in collision chains worldwide. Frequently mirroring the summits of mountain systems, they elegantly encapsulate the concept of isostasy. The rugged topography of northern Iberia results from convergence with the European plate during the Alpine orogeny that formed the Pyrenean-Cantabrian mountain range. From east to wes...
Article
Full-text available
The plate kinematics of the Iberian plate and their implications on the plate tectonic evolution of the Bay of Biscay during rifting and subsequent opening of the southern North Atlantic continue to be topics of scientific discussion and debate. Constrained by previous plate reconstruction, geophysical, and geological studies, deformable plate tect...
Article
Full-text available
Despite considerable progress in restoring rifted margins, none of the current kinematic models can restore the Mesozoic motion of the Iberian block in full agreement with the circum‐Iberian geology. This conflict requires a revision of the kinematic description at onset of divergence. The circum‐Iberian region has a unique geological dataset that...
Article
Current rift models propose polyphase rift evolutions that develop with the same kinematic framework and accommodate continuous and sequential extension, through the stacking of deformation modes. Several rifted margins show, however, evidence for multiple and out of sequence rift events, which developed within different kinematic frameworks, with...
Conference Paper
Full-text available
In this work, we address the problem of the formation and reactivation of multi-stage rifting based on the study of the central North Iberian margin, located at the southern Bay of Biscay triangular oceanic domain. This magma-poor rifted margin registered three major Mesozoic rift events and a subsequent Alpine compressional reactivation, represent...
Chapter
Full-text available
The Permian-Triassic rifting represents the first of the two Mesozoic rifting stages recorded in the Iberian Peninsula. Its first phases of development started during the Early Permian, and were linked to the beginning of the break-up of Pangea, the large, unique and rheologically unstable supercontinent that mainly resulted from the collision of G...
Conference Paper
Full-text available
Nowadays, it is widely agreed that rifting is a polyphase and strain localisation process which implies the stacking of successive deformation events [e.g., Bulk, 1990; Lavier & Manatschal, 2006; Péron-Pinvidic & Manatschal, 2009]. At distal parts in magma-poor rifted margins, crustal thinning and exhumation of lower crustal and mantle rocks give p...
Article
The Pyrenean-Cantabrian Orogen arose through the collision of the Iberian and Eurasian plates, mostly in Cenozoic times. This orogen comprises two main mountain ranges, the Pyrenees to the east, and the Cantabrian Mountains to the west. To date, the early Alpine tectono-sedimentary phases preserved in the Cantabrian Mountains, of Permian and Triass...
Conference Paper
Full-text available
There is broad agreement that the structure of rifted margins results from the evolution of successive deformation modes linked to tectonic activity. However, the progressive spatial and temporal evolution of rifting leading to strain localization and structural segmentation are still poorly understood. The strongly segmented Bay of Biscay rift sys...
Conference Paper
Full-text available
It is widely agreed that the architecture of rift systems is controlled by the evolution of successive deformation modes linked to tectonic activity. However, progressive spatial and temporal strain localization, and the resulting structural segmentation characterizing rifted margins are still poorly constrained. The Bay of Biscay rift is a strongl...
Conference Paper
Full-text available
While the architecture and tectonic evolution of mature orogenic belts have been extensively studied, the initial reactivation of rifted margins leading to subduction and eventually to mountain belts is yet little understood, partly because these systems are only preserved in rare cases. The Pyrenean-Cantabrian orogen developed along the European-I...
Article
The Alpine Pyrenean-Cantabrian orogen developed along the plate boundary between Iberia and Europe, involving the inversion of Mesozoic hyperextended basins along the southern Biscay margin. Thus, this margin represents a natural laboratory to analyse the control of structural rift inheritance on the compressional reactivation of a continental marg...
Conference Paper
Full-text available
This study presents a new rift domain map in the central and western North Iberian margin, in the southern Bay of Biscay. This margin was structured during polyphase Triassic to Lower Cretaceous rifting events which led to hyperextension and exhumation and the formation of oceanic crust during a short-lived seafloor spreading period. Extension was...
Conference Paper
Full-text available
The Bay of Biscay-Pyrenean geological system is an inverted hyperextended rift that illustrates in its deep structure the transition between an oceanic underthrusting in the west to a continent-continent collision in the east. We developed a structural analysis of the southwestern reactivated rift system, which represents at present-day the western...
Article
The distribution and structure of the Mesozoic and Cenozoic cover within the central part of the North Iberian Margin (Bay of Biscay) is analyzed based on a dense set of 2D seismic reflection lines and logs. The integration of well data allows the recognition of seven seismostratigraphic units and the construction of a surface that illustrates the...
Conference Paper
Full-text available
The Bay of Biscay is a V-shape failed arm of the Atlantic rift, which was opened during the Mesozoic and partially closed during the Alpine orogeny in the Cenozoic, when the convergence of the Iberian and European Plates drove to the formation of the Pyrenean-Cantabrian realm in the North Iberian peninsula. A complete crustal cross section through...
Conference Paper
Full-text available
A new dense set of high quality 2D seismic reflection profiles together with several boreholes and well logs, recorded in the Bay of Biscay for oil and gas exploration purposes, have been studied at the central part of the North Iberian Margin. The integration of well data within the seismic profiles allowed the recognition of the main structures a...
Conference Paper
Full-text available
The geological interpretation of the Cantabrian Platform in an area that extends close to 12.000 km 2 is presented here from the analysis of a dense set of 2D seismic reflection profiles together with boreholes and well logs. The structure is the result of the complex paleogeographic evolution of the Iberian Plate since the Permian. During the meso...
Article
Full-text available
The Cantabrian Fault is a long-lived crustal fault, 320 km long on land and extending more than 150 km seawards within the Bay of Biscay, which separates different geodynamic domains. Due to its sub-vertical dip and late strike slip movement is poorly evidenced in the shelf and it has been traditionally mapped following the strike of the deepest su...
Conference Paper
Full-text available
The Ándara Lake constituted the third mass of water by extension (approximately 19000 m2) within the calcareous Picos de Europa Massif in NW Spain, but only a small pond remains today (about 1250 m2). The lake developed in a former glacial valley and its sudden draining occurred in the second decade of the 20th century, during the development of un...
Conference Paper
Full-text available
This study shows a 3D geological interpretation of Le Danois Basin from the analysis of a dense set of high quality seismic reflection profiles together with boreholes, well logs and previous studies.
