Resumen

Taking into account previous detailed stratigraphic and facies analyses carried out in the Alpujarride succession from the Sierra de Gádor (Almeria province) and correlations with other sectors, we propose a synthetic stratigraphic column for the Alpujarride Triassic Platform; this column consists of two formations: a basal meta-siliciclastic formation (divided in three members, from base to top: lower, middle and upper) Anisian in age, and an overlying meta-carbonate formation (divided in six members, 1 to 6 from base to top) Anisian-Norian in age. We postulate a morphological evolution of the Alpujarride Triassic Platform including three phases: an Anisian-Ladinian homoclinal ramp first phase, a Ladinian-Carnian fault-block-type platform second phase, and a Norian rimmed platform third phase. We also divide the Anisian-Norian stratigraphic record in four depositional sequences (DS). DS1 should comprise the lower and middle members of the meta-siliciclastic formation; DS2 should be formed by the upper member of the meta-siliciclastic formation and members 1 and 2 of the meta-carbonate formation; DS3 should consist of members 3 and 4; SD4 should be composed of members 5 and 6.
