Carbonatites are igneous rocks formed in the crust by fractional crystallization of carbonate-rich parental melts that mostly mantle derived. They dominantly consist carbonate minerals such as calcite, dolomite, and ankerite, well minor ...Read More
Summary In a preliminary series of experiments, using physical models mechanical processes extensional tectonics have been investigated at various scales. By suitable choice model materials, experiments were performed low cost in natural gravity field. Upper layers the lithosphere modelled sand; lower layers, silicone putties two different densities; mantle asthenosphere was honey. The deformed under their own weight or absolute horizontal tension. Rates extension controlled stepper motor....
Scaled physical models illustrate the importance of progradation as a trigger for salt tectonics and formation allochthonous sheets. Regional extension contraction were excluded in models. In our experiments, prograding wedges above tabular, buoyant layer with flat base expelled basinward, forming following structures proximally to distally: (1) sigmoidally distorted initially planar wedges, (2) relict pillows welds, (3) basinward-dipping expulsion rollover crestal graben, (4) syncline, (5)...
Using conceptual reasoning and results from physical models, we describe the mechanical kinematic characteristics of sediment wedges spreading seaward above a viscous evaporitic layer. Spreading can occur if distal overburden is thin weak, or it comprises preexisting salt bodies. accommodated by proximal extension an associated rise diapiric ridges, midslope translation, shortening. Rapid progradation lead to reactivation older folds later extension. Either retrogradation renewed...
Scaled experiments, whose design was based on recently published low values for the viscosity of natural rocksalt, suggest that under typically geological extension rates, a salt layer 500 m thick or thicker decouples brittle overburden from faulted basement. Because its viscosity, cannot transmit large differential stresses necessary basement faults to propagate upward as abrupt forced folds into overburden, unless is thin has been depleted. Thick diffuses localized deformation in by...

Convergence between African and European plates generates compressional strain, primarily concentrated along the northern margin. This is testified on Algerian margin by numerous earthquakes (e.g. Bougrine et al., 2019) presence of active folds thrusts. Multi-channel seismic reflection profiles from MARADJA I survey reveal north-verging thrusts rooted below Messinian units, geometries salt structures. study examines characteristics o+ tectonics offshore Algiers Dellys, focusing effect...
