The Main Ethiopian Rift (MER) has a complex structural pattern composed of southern, central, and northern segments. Ages onset faulting volcanism apparently indicate heterogeneous time‐space evolution the segments, generally referred to as northward progression rifting process. New structural, petrological, geochronological data have been used attempt reconciling distinct MER segments into volcanotectonic scenario accounting for propagation Afar Kenya Rifts. In this evolutionary model,...

Small‐scale modeling was performed to examine the effects of superposition two successive extensional phases from orthogonal oblique (type 1) and 2). In both type 1 2 models, faults produced during first stage strongly control fault development second stage. developed phase are confined within a first‐phase graben, whereas in models faults, phase, continue develop extension connect with each other give sigmoidal blocks. Type compared structural setting Ethiopian Rift; evolution rift is...
The Northern Apennines (NA) hinterland area is characterized by a complex Neogene‐Quaternary tectonics where both crustal extension, associated with the Tyrrhenian Basin opening, and shortening in onshore took part deformation. Analysis of synorogenic deposits preserved NNW trending Siena‐Radicofani (SRB), extending along large NA hinterland, documents evolution deformation this sector during last 9 Ma. Information from subsurface geology (deep seismic lines, commercial deep wells), surface...
The Main Ethiopian Rift (MER) is a narrow continental rift characterized by an along‐axis variation in evolution, with early stages the south evolving to incipient breakup north. Although distribution and style of Quaternary volcanotectonic deformation well known northern sector, knowledge these characteristics comparatively less constrained southward. In this paper we present results field structural study carried out better constrain time‐space faulting central sector MER (central MER)....
Abstract Continental rifting is a geodynamic process that involves the breakup of crust and may eventually evolve to seafloor spreading. Although it often assumed be product orthogonal divergence, continental result from oblique extension, in several cases, related rotation plates or crustal blocks about vertical axis. This implies occurrence rifts with straight but not parallel margins rift axis‐parallel gradients extension velocity amount strain. The effects propagation through has only...
A set of scaled analogue models was performed to investigate the role a décollement layer in structural style fold‐and‐thrust belts. Silicone putty (SGM 36) has been employed represent ductile décollement, while frictional material (quartz sand) used simulate brittle behavior roof and floor sequences, situated above below respectively. In order explore wide combination strength profiles, have deformed under five distinct rates compression (0.15, 0.3, 0.45, 0.6, 1.5 cm h −1 ) employing four...
Small‐scale centrifuge models were used to investigate the role of continental rift structure in controlling patterns magma migration and emplacement. Experiments considered reactivation weakness zones lower crust presence at Moho depths. Results suggest that surface deformation, which reflects zone geometry, exerts a major control on migration. In case single segment, experimental both transferred an extension‐parallel direction toward flanks. This lateral reflected dominance far‐field...
Abstract Southern Ethiopia is a key region to understand the evolution of East African rift system, since it area interaction between main Ethiopian (MER) and Kenyan rift. However, geological data constraining in this remote are still relatively sparse. In study timing, distribution, style rifting southern constrained by new structural, geochronological, geomorphological data. The border faults roughly parallel preexisting basement fabrics progressively more oblique with respect regional...
The behaviour of a granular material is mainly dependent on its frictional properties, angle internal friction, and cohesion, which, together with density, are the key factors to be considered during scaling procedure analogue models. properties usually investigated by means technical instruments such as Hubbert-type apparatus ring shear testers, which allow for investigating response tested wide range applied stresses. Here we explore possibility determine different empirical methods...
