IntroSystStrat2 - Fernando Pessoa University

Universidade Fernando Pessoa. Porto, Portugal. Salt Tectonics Short Course Introduction. Salt Tectonics (fig. 1) has been defined as any tectonic deformation of a sedimentary package involving salt, or other evaporites as a mobile substratum or mobile layer.In this sense, salt tectonics is not a synonym of Halokinesis, which labels a sedimentary deformation powered

Salt tectonics, or halokinesis, or halotectonics, is concerned with the geometries and processes associated with the presence of significant thicknesses of evaporites containing rock salt within a stratigraphic sequence of rocks. This is due both to the low density of salt, which does not increase with burial, and its low strength.. Salt structures (excluding undeformed layers of

Jan 07, 2021 · Salt tectonics and magmatism are prevalent in many sedimentary basins worldwide. It is thus inevitable that, in some places, magma will interact with salt as it ascends towards the surface.

Two main types of salt extrusion are examined. In the case of active extrusion, salt rises to the surface at a velocity of about 30–35 cm/yr, forming a salt dome about 550 m in height. In the case of passive extrusion, the velocity of salt extrusion from under a newly developing sedimentary minibasin is significantly lower.
