Basic data. The geology of Santiago de Cuba (Fig. 1) is characterized by the presence of volcanic and volcanic-sedimentary rocks of Paleogene age, such as: tuffs, tuffites, lavas, and so on, often crossed by intrusions of igneous rocks; this group crops out in the mountainous parts and also in other parts of the city. Marls, conglomerates, argillites, and limestones of Neogene age, occupy almost the entire basin, plateaux and the coastal hills. Recent sediments of Quaternary age, such as clays, sands, and gravels [for more details, see Rivera et al . (2013)] are located in the proximity of the coast and floodplains. The basement of the basin is mainly Fig. 1 – Summary of the main stratigraphic units present in the study area with distribution of the 61 profiles (grey lines) and an example of geological interpretation in depth.
