Este trabajo constituye una revisión de estudios previos sobre las características más destacadas de la playa de Las Canteras desde el punto de vista geomorfológico y sedimentológico. Respecto al primero de estos aspectos se presta especial atención al beachrock que constituye la barra y que también aflora en distintos puntos del frente de playa. Tras una somera descripción del entorno geológico en que se encuadra y de las características oceanógraficas de la zona, se presenta una caracterización granulométríca y composicional de los sedimentos de la playa, haciendo hincapié en las variaciones espacio-temporales que presentan. Se hace igualmente un análisis de la variabilidad sedimentaria de esta playa, sometida a cambios estacionales muy marcados, pero donde lo más llamativo es la tendencia a acumular sedimentos a largo plazo, sedimentos que proceden de un banco submarino localizado en los fondos de la bahía del Confital.
This paper is a review of previously published studies on the geomorphological and sedimentological characteristics at Las Canteras beach. Regarding the formeí aspect, special focus is pointed out at la barra, a beachrock Ihat extends 200 meters offiihore parallel to the shoreline and that also crop out at different sectors of the beach face. Once the geological setting and the oceanographic conditions in the area are presented, the grain size and compositional properties of the beach sediments are described, focussing on the time-space variations. Regarding the sediment dynamics, this beach shows a very strong seasonality with opposite patterns in the northern and southern sectors of the beach, which denotes and intense longshore transport. Apart from that, the beach shows a long term tendency to accumulate sands in the northern sector, sediments that come from a submarine bank located in Confital bay.
