dc.description.abstractThe heavy minera!, distribution on recent sediments of continental shelf of Cadiz; shows great relation with the granulómetric distribution, -source areas, hydrodynamic behavior grains and the depositlonal regimen. Ultrastable heavy minerals are predominate in south sector, in coincidence with quarzitic sand deposits sedimentation low rate and high maturity of the sediments. Nortward, in neighboring prodeltaic muddy sediments to the Guadalquivir aver mouth, meta stables heavy minerals predominate, in coincidence with high sedimentation rate and a greater mineralógica! variability in the sediments, dye to the. fluvial contribution. The main mineralógica! assemblage is: epi dote, garnet, rutile and zircon, very similar to the. sho wed by other in neighboring littoral and continental, areas. The main source areas are in the Iberian Masif(Sierra Morena), Cordillera Be tica and Depresión óf Guadalquivir. The main transport agents are the Guadalquivir and Guadalete rivets and others which ha ve their mouth nortward of the study area. Others sources of sediments to the. continental margen can be related with the Atlantic Water Flow and, Mediterranean Out Flow from external zones to this geographical areaen_US
