Resumen
The coastal strip between Trafalgar and Punta Paloma, is characterized by the development of a karstic complex that affects the Last Interglacial marine terraces (OIS 5c ~100 ka, Fig. 1), there composed of well cemented conglomerates and sandstones. Two different morphologies are recorded, both related to different genetic models: "solution pipes" controlled by climatic changes (switch from humidity to aridity), and "horizontal tubules" controlled by changes in base level. The origin and palaeoenvironmental meaning of these karstic forms are described for the first time in the littoral of Cadiz, within a chronological framework based on OSL (Optically Stimulated Luminescence) and U/Th (alpha and TIMS) dating.
