Título: Evolução paleogeográfica e paleobiogeográfica do Caloviano-Kimeridgiano do Algarve

Resumo: The littoral and the «barrocal» of the Algarve correspond in part to a meso-cenozoic sedimentary basin with a deeping south monocline structure, cut by North-South faults and by two East-West longitudinal flexures. The lithostratigraphic and chronostratigraphic study of the Jurassic formations, undertaken during the last years, allow a better knowledge of the paleogeographic and paleobiogeographic evolution of these formations and particularly of the Callovian-Kimmeridgian. Lower Callovian facies, being similar from Sagres in the West to beyond Tavira, show the uniformity of the sedimentary conditions. Since Middle Callovian, the beginning of the regressive cycle is responsible for a major unconformity between Dogger and Malm. During the Lower Oxfordian a new sedimentary cycle begins with a transgression afecting the region south of the Albufeira-São Brás de Alportel-Tavira line thus originating a gulf centered in the Loulé area which rapidly diminishes since the Lower Kimmeridgian. The faunistic affinities are always tipically tethyan although some classic boreal fauna exist, in contrast with the Northern Tagus basin (where affinities are sub-boreal during the Callovian).
