Figure F7. Interpretative sketches of the Quaternary evolution of the buried mounded drift deposits in the channels and ridges sector of the middle slope of the Gulf of Cádiz (from Llave et al., 2007b). GB = Guadalquivir Bank, DDR = Doñana diapiric ridge, GDR = Guadalquivir diapiric ridge, CDR = Cádiz diapiric ridge. A. Overview of the oceanographic patterns in the Gulf of Cádiz. MOW = Mediterranean Outflow Water, MU = Mediterranean upper water, ML = Mediterranean lower water, IB = intermediate branch, PB = principal branch, SB = southern branch. Square with discontinuous lines represent the area for B,C and D reconstructions. B. Active Guadalquivir and Huelva Drift growth stage (early to mid-Pleistocene) C. Late-stage drift growth (mid- to late Pleistocene). D. Complete drift burial (late Pleistocene and Holocene) when the present morphologic configuration of this sector was generated by new oceanographic conditions of ML.
