Abstract The anisotropy of magnetic susceptibility (AMS), and other fabric techniques have been tested in a multilayer system Eocene turbidites from the Southern Pyrenees. identified fabrics can be grouped into (1) related to layer parallel shortening (LPS) acquired pre‐folding conditions, (2) cleavage development (3) shear thrust movement intermediate cases. AMS depends on (i) paramagnetic contribution (ii) position sites fold‐thrust belt. study southern Pyrenees shows that processes...
In this work we present an analysis of the applicability ground penetrating radar (GPR) to karstic hazard evaluation in urban areas by means several case studies. The main objective is characterize origin pathologies buildings and other facilities, subsidence processes, identify their causative phenomena subsoil. This study involves resolution, penetration characteristics noise affecting GPR signals areas. analyzed studies are located Central Ebro Basin (NE Spain), where hazards related...
Abstract Magnetic susceptibility in rocks is the sum of contributions different magnetic particles (paramagnetic, diamagnetic and ferromagnetic s.l.). These can be measured at variable temperatures or fields (hysteresis loops). Both are time‐consuming techniques that cannot routinely used fabrics analysis. In this study, we propose a simplified method to determine ferro‐ paramagnetic susceptibility, based on discrete measurement two (near 0 2.5 T). The results obtained samples from Southern...
Abstract The low contrast in physical properties of archaeological elements compared to the host soil is a common drawback geophysical surveys applied subtle sites because those contrasts are usually what being measured by most instruments. Furthermore, when and construction remains placed within same package materials, differentiation each can make interpretation data sometimes difficult. In this work we propose dynamic, integrated approach for characterization an site with simple Roman...
Magnetic fabric analysis can be used as a tool to investigate tectonic processes and deformational events but the manner in which studied fabrics were acquired blocked must also carefully considered. In studies using anisotropy of magnetic susceptibility (AMS), timing AMS moment acquisition its blocking identified. The former term refers preferred orientation ellipsoid while latter is last process that inferred modify it. this paper, very early diagenetic analysed synsedimentary slump...
The Quaternary Añavieja-Dévanos tufa system is located in the northern sector of Iberian Chain. It has been previously tackled by means sedimentological studies focused on available outcrops and some boreholes. They have permitted proposal a sedimentary scenario that fits with pool-barrage fluvial model. However better knowledge characteristics internal distribution usually non-outcropping pool deposits as well its relationship barrage not evaluated detail yet. Palaeoenvironmental tufas are...
Evaluation of karst hazards benefits from the integration different techniques, methodologies and approaches. Each one presents a signature is sensitive to certain indicators related hazards. In some cases, detailed analysis permits evaluation representativeness either isolated approaches or by means integrated analyses. this study, we present an area with high density karstic collapses at evolutionary stages through surficial, historical, geomorphological geophysical data in order finally...
