Focal Mechanisms for Subcrustal Earthquakes Beneath the Gibraltar Arc

Earthquakes below 50‐km depth are usually associated with active subduction, and the direction of faulting is aligned with the orientation of the subduction zone. Faulting in 42 earthquakes beneath the Gibraltar Arc and Alboran Sea shows different characteristics. The most abundant solutions show horizontal slip, in agreement with relative plate motion between Africa and Europe. Further solutions are associated with shortening and suggest compression from the basal drag of the Earth's mantle on the moving plates. In turn, no signature of active subduction was found. Images of the Earth's interior from teleseismic waves suggest a relation between the earthquakes and a stalled remnant of ~150‐Ma‐old oceanic material that once formed the connection between two oceans and later has been buried beneath the Gibraltar Arc.We received financial support through Mineco/Feder Project CGL2015‐67130‐C2‐2‐R and Junta de Andalucía research group RNM 10

Design an Amperometric Biosensor for the Detection of Lactate

In this study, we present the design of a new electrode material, as a L-lactate selective electrochemical sensor. We identified the conditions under which the mediator DHB-Nafion provides the best reversibility and robustness. We also found that by using a Nafion overlayer 50% of modified material is preserved. With these conditions the electrochemical detection of NADH is carried out. By adding to the molecular electrode's material L-LDH enzyme, the detection is accomplished at different concentrations of L-lactate. Finally we performed the determination of L-lactate under hydrodynamic regime. The working potential under hydrodynamic regime is 0.56 V vs. Ag/AgCl (pH 7.4) in 50 mM phosphate buffer with 50 mM KCl as supporting electrolyte. The results from the calibration curve obtained by linear regression was 0.9826 at concentrations from 0.0 to 0.6 mM of L-lactate, and 0.9738 at concentrations from 0.7 to 0.11 mM of L-lactate

A STEP fault in Central Betics, associated with lateral lithospheric tearing at the northern edge of the Gibraltar arc subduction system

We study the crustal and lithospheric mantle structure under central Betics in the westernmost Mediterranean region by migrating P-receiver functions along a dense seismic profile (∼2 km interstation distance). The profile, North–South oriented, probes the crustal structure of different geological units, from the Alboran domain in the south with metamorphic rocks, through the External Zones with sedimentary rocks to the Variscan terrains of the Iberian Massif in the north. From north to south, the Moho depth increases from ∼30 km to ∼46 km underneath the Guadix basin, due to the underthrusting of the Iberian crust below the Alboran crust, and suddenly shallows to ∼30 km underneath the Internal Zones with a step of 17 km. This sharp Moho step correlates well with a lithospheric step of ∼40 km, where the thickness of the lithosphere changes abruptly from ∼100 km in the north to ∼50 km in the south. We interpret this sharp and prominent lithospheric step as the termination of the Iberian lithosphere caused by a near-vertical STEP (Subduction-Transform-Edge-Propagator) fault that continues towards the surface as a positive flower tectonic structure of crustal scale. This STEP fault is located at the northern edge of the narrow Westernmost Mediterranean subduction system facilitating the slab rollback motion towards the west. The sharp termination of the Iberian lithosphere occurs under the contact between the Alpujarride and the Nevado-Filabride complexes of the Alboran domain in an ENE-WSW right-lateral transpressive shear zone. The thickest crust and lithosphere do not correlate with the highest topography along the profile suggesting that this high topography is a combined effect of the positive flower structure, and the push up of the asthenosphere produced by the removal of the Iberian lithosphere.This work was sup-ported by the projects: CGL2015-67130-C2-2-R, GCL2012-31472 (TRANSCORBE), HIRE (GFZ Potsdam) and PP2012-PIJD003 (Granada University).
