Granite intrusion in the upper crust along a crustal-scale shear zone has been modelled by injecting Newtonian fluid (low-viscosity silicone putty) into sandpack containing ductile layer of putty which acted as weak level injected material could spread. The strike-slip regime was obtained using two mobile rigid basal plates sliding horizontally. Boundary conditions were chosen order to analyse influence thicknesses brittle cover and volume on pattern intrusion. Experiments showed that (1)...
Abstract Large‐scale faults in the continental crust are significant features that control evolution of sedimentary basins and intraplate mountain chains. Deciphering their is a task because slip reactivate variety geological settings. In this work, clay gouges two major orogen‐scale, long‐lived northern Iberia, Río Grío Vallès‐Penedès Faults, were investigated by X‐ray diffraction K‐Ar isotopic analysis. Illite polytype determinations 44 subfractions (from <0.1 to 10 μm) allowed us...
The accurate identification of dinosaur egg accumulations as nests or clutches is crucial for understanding the reproductive behaviour these extinct species. However, existing methods often rely on presence complete eggs and embryo remains, sedimentological criteria that are only applicable to well-structured sediments. In this study, we introduce an innovative approach characterize in structureless sediments, where traditional nest structures may not be preserved. Our methodology employs a...
A laccolithic geometry is inferred from geological and geophysical data for the La Tojiza granitic body emplaced in an extensional regime. Nearly circular outcrop, this 16 km diameter pluton, one of so-called ‘post-tectonic granodioritic plutons’ Galicia, located northern Variscan arc Iberia, within Mondoñedo Nappe (Western Asturian–Leonese Zone). From anisotropy magnetic susceptibility measurements extensive microstructural data, fabric pluton has been to correlate with magmatic fabric....
The timing of development the magnetic fabric is a major issue in application anisotropy susceptibility (AMS) as strain marker. Analysis AMS unconcealed synsedimentary structures can be sound approximation to this task. In work, three types early compactional (ECS) were studied by means AMS, since they help understand fabric. All ECS are found fine-grained detrital rocks (to avoid other influences such palaeocurrents), claystones and marls Enciso Group within Cameros Basin (NE Spain):...
This work includes, first, a synthesis of experimental analogue modelling programs assessing the influence along-strike thickness variations in development oblique structures fold-and-thrust belts. As second part, we present new program testing, systematically, tapered décollement-cover thrust wedges. Previous experiments show that frictional, brittle models feature numerous, short-wavelength where cover is thinner. Deformation fronts are totally or locally to backstop when thinning...
In this paper, we report on a compilation of more than 2200 sites (more 10,000 individual measurements) where anisotropy magnetic susceptibility (AMS) was studied in granites from the Variscan Pyrenees. The standardization and homogenization information has allowed us to produce three Main Maps that synthesize all related with AMS Pyrenean granites. We also describe problems found during construction database (variable geo-positioning, different published information, etc.). derived 21...
Abstract Granite emplacement in the brittle crust can be modelled by means of injection a Newtonian fluid (low-viscosity silicone putty) into sandpacks. This paper describes dynamically scaled analogue models granite intrusions upper under different tectonic regimes. Experiments analyse three boundary conditions: (1) static conditions, with rheological profiles (single sand-layer system, two-layer silicone-sand three-layer sand-silicone-sand system and five-layer...
