Crust (geology) crustal rocks formed before 2.5 billion years ago are located in cratons. Such old continental crust and the underlying mantle asthenosphere are less dense than elsewhere in Earth and so are not readily destroyed by subduction. Formation of new continental crust is linked to periods of intense orogeny; these periods coincide with the formation of the supercontinents such as Rodinia, Pangaea and Gondwana. The crust forms in part by aggregation of island arcs including granite and metamorphic fold belts, and it is preserved in part by depletion of the underlying mantle to form buoyant lithospheric mantle.

Salt crust was tested by trained professionals who concluded that the baking of the fish in a salt crust was satisfactory in terms of sensory characteristics. Some of the trained panelists added more salt to the dish. Hence it can be deduced that the dish can be readily eaten by people who suffer from various illnesses like hypertension. Salt crust Salt crust is the name given to the method of covering of an ingredient, commonly fish such as sea bass and grouper, in a sand-like mixture of usually egg whites and salt. The salt acts as insulation and helps cook the food
