The peridotites of Sierra Alpujata thrust to the north a formation of granitoid gneisses and the succession of Sierra Blanca. This structure led to the individualization of the unit of this name, and thus it is considered to crop out in a tectonic window. Nevertheless, on the western border of Sierra Alpujata the gneisses, in continuity with the formations of Sierra Blanca, are situated over the peridotites. This means that the Sierra Blanca does not crop out in a tectonic window, and that the peridotites, on the whole, are in fact situated in a lower position. This situation has important consequences for the age of their first exhumation and for the geological evolution and structure of the region.
