摘要
The Symposium ＂The Geology of the Gulf of Cádiz＂ was organised as part of the scientific activities of the Ⅵ Geological Congress of Spain, celebrated in Zaragoaz. Spain from July 12 to 15, 2004. Most of communications reflect European cooperative research within the framework of the ESF EuroCORE-Euro-MARGINS programme within the projects CVSEIS （Mud Volcanoes in the Gulf of Cádia）, MOUNDFORCE （Deep Reefs associated with Methane Seeps） and SWIM （South-West Iberia Margin： seismogenic faults）. The Gulf of Cádiz is situated in a tectonically very active region, in a complex setting near a major plate boundary characterized by a combination of important strikeslip movement （along the Azores-Gibraltar fracture zone in the central eastern Atlantic） and compressional tectonics related to the Africa-Eurasia convergence. This area is characterized by extensive mud volcanism, salt tectonics, mud diapirism and carbonate chimneys related to hydrocarbon rich fluid venting.
