Deep Crustal Structure Of The Area Of Intersection Between The Shackleton Fracture Zone And The West Scotia Ridge (Drake Passage, Antarctica)

6th International Congress of the Brazilian Geophysical Society (1999)

Andrés Maldonado Jesús Galindo‐Zaldívar A. Jabaloy José Miguel Martı́nez-Martı́nez Carlos Sanz de Galdeano

The Shackleton Fracture Zone represents the present-day boundary between the Antarctic and Scotia plates in the Drake Passage. The West Scotia Ridge is an extinct spreading center, which formed the oceanic crust of the Scotia Plate in this region and that intersects with the Shackleton Fracture Zone. New multichannel seismic, gravimetric, magnetometric and multibeam swath bathymetry data were acquired during the ANTPAC 97/98 cruise with the Spanish vessel B/O HESPERIDES in the area and reveal that these structures are asymmetric and developed as a consequence of the overprinting of extensional and contractional deformation events. Thrusting of these young oceanic crusts produces crustal thickening and shallow oceanic reliefs and ridges.

Eemian marine terraces along the Pacific coast of South America (1°N-40°S) allow regional assessments of tectonic forcing from earthquake cycle to glacial-cycle timescales

Roland Freisleben Julius Jara‐Muñoz Daniel Melnick José Miguel Martı́nez-Martı́nez Manfred R. Strecker

Abstract. Tectonically active coasts are dynamic environments characterized by the presence of multiple marine terraces formed by the combined effects of wave-erosion, tectonic uplift, and sea-level oscillations at glacial-cycle timescales. Well-preserved erosional terraces from the last interglacial sea-level highstand are ideal marker horizons for reconstructing past sea-level positions and calculating vertical displacement rates, which can be subsequently compared to short-term coastal deformation patterns associated with the earthquake cycle. We carried out an almost continuous mapping of the last interglacial marine terrace along ~5,000 km of the western coast of South America between 1&#176;N and 40&#176;S. We used quantitatively replicable approaches constrained by published terrace-age estimates to ultimately compare elevations and patterns of uplifted terraces with tectonic and climatic parameters in order to evaluate the controlling mechanisms for the formation and preservation of marine terraces, and crustal deformation. Uncertainties were estimated on the basis of measurement errors and the distance from referencing points. Overall, our results indicate a median elevation of 30.1 m, which would imply a median uplift rate of 0.22 m/ka averaged over the past ~125 ka. The patterns of terrace elevation and uplift rate display high-amplitude (~100&#8211;200 m) and long-wavelength (~102 km) structures at the Manta Peninsula (Ecuador), the San Juan de Marcona area (central Peru), and the Arauco Peninsula (south-central Chile). Medium-wavelength structures occur at the Mejillones Peninsula and Topocalma in Chile, while short-wavelength (< 10 km) features are for instance located near Los Vilos, Valpara&#237;so, and Carranza, Chile. We interpret the long-wavelength deformation to be controlled by deep-seated processes at the plate interface such as the subduction of major bathymetric anomalies like the Nazca and Carnegie ridges. In contrast, short-wavelength deformation may be primarily controlled by sources in the upper plate such as crustal faulting, which, however, may also be associated with the subduction of topographically less pronounced bathymetric anomalies and varying distances to the trench. Latitudinal differences in climate additionally control the formation and preservation of marine terraces. Based on our synopsis we propose that increasing wave height and tidal range result in enhanced erosion and morphologically well-defined marine terraces in south-central Chile. Conversely, river incision and lateral scouring in areas with high precipitation may degrade marine terraces. Our study emphasizes the importance of using systematic measurements and uniform, quantitative methodologies to characterize and correctly interpret marine terraces at regional scales, especially if they are used to unravel tectonic and climatic forcing mechanisms of their formation.

Crustal decoupling and intracrustal flow beneath domal exhumed core complexes, Betics (SE Spain)

Terra Nova (1997)

José Miguel Martı́nez-Martı́nez Juan I. Soto Juan Carlos Balanyá

ABSTRACT The Sierra Nevada core, located in the Betic hinterland, features a N‐S large‐scale open antiform with a central relatively uplifted highly extended domain placed between two less extended domains (in the east and in the west) dipping eastwards and westwards, respectively. The core‐bounding detachment system formed during the Serravallian (15–11 Ma) in an episode of ENE‐WSW extension. The ESCI‐Beticas 2 deep seismic reflection profile, a transect through the core, shows a highly reflective deep crust overlying a subhorizontal Moho, and a fairly transparent upper crust and upper mantle. The lack of Moho relief beneath this area, with differential values for supra‐crustal thinning, suggests a mechanism of intracrustal isostatic compensation. Surface geology data together with seismic imaging indicate intracrustal flow and upward doming as a response to footwall unloading accompanying the middle Miocene supracrustal extension. A prominent mid‐crustal reflector (MCR) is deemed to represent a decoupling zone between the upper and the deep crust. Subsequent N‐S shortening and associated folding occurred in the late Miocene. The interference pattern of this folding over the middle Miocene core produced the current E–W dome‐shaped tectonic windows where the deepest complex of the Betic hinterland crops out.

Metamorfismo de AP/BT en metapelitas de la unidad de Ragua (complejo Nevado-Filábride, Cordillera Bética). Resultados termo-barométricos del estudio de equilibrios locales.

Geogaceta (2003)

Guillermo Booth‐Rea José Miguel Azañón Hernández José Miguel Martı́nez-Martı́nez

We have analysed the thermobarometric equilibrium conditions reached during local equilibria among phengite + chlorite + quartz + water ± chloritoid ± garnet assemblages found in metapelites of the Ragua unit, the structurally-Iowest tectonic unit outcropping in the Betics hinterland (southern Spain). Porphyroblast- deformation relationships show that lenticular domains preserved within the main foliation in the metapelites grew during a HP/LT prograde metamorphic event with thermal conditions of 320-450oC and 12 - 14 kbar pressure. Hence, the Ragua unit subducted in a continental accretionary-wedge context, undergoing a tectonic evolution parallel to the one followed by the two other overlying Nevado-Filabride units.

Autopsy on a dead spreading center: The Phoenix Ridge, Drake Passage, Antarctica

Geology (2000)

Roy Livermore Juan Carlos Balanyá Andrés Maldonado José Miguel Martı́nez-Martı́nez J. Rodrı́guez-Fernández

New bathymetric and magnetic anomaly data from the Phoenix Ridge, Antarctica, show that extinction of all three remaining segments occurred at the time of magnetic chron C2A (3.3 ± 0.2 Ma), synchronous with a ridge-trench collision south of the Hero Fracture Zone.This implies that the ultimate cause of extinction was a change in plate boundary forces occasioned by this collision.Spreading rates slowed abruptly at the time of chron C4 (7.8 ± 0.3 Ma), probably as a result of extinction of the West Scotia Ridge, which would have led to an increase in slip rate and transpressional stress across the Shackleton Fracture Zone.Spectacular, highrelief ridges flanking the extinct spreading center, mapped for the first time using multibeam swath bathymetry, are interpreted as a consequence of a reduction in spreading rate, involving a temporary magma oversupply immediately prior to extinction.
