The project “Geological Research and Basic Cartography in the Pyritic Strip and surrounding areas” (ICFP), which was undertaken by the Mine Service in collaboration with the Geological Mining Institute of Spain, was carried out between 1997 and 1999 and is a deepening of the previous work developed in this same area by both agencies. The successful companies were a Temporary Union of Companies, INFAPIR, formed by INIMA, INGEMISA and EPTISA, and the company CGS. This project includes the study area of the Geology of the Guadalquivir Valley, corresponding to the surrounding areas, mentioned in the title of the project. The scope of the project had the following objectives: — Update of the basic geological mapping published by the IGME within the MAGNA program (National Geological Map at 1:50,000 scale). — Update of geological mapping at 1:200,000 scale. — Definition of stratigraphy of the Guadalquivir Basin. — Sedimentological and petrological characterisation of lithostratigraphic units. — Knowledge of the tectonic evolution of the area of study, with geological cuts that have allowed the interpretation of the structures. — Integration of the geophysical information of the subsoil and the soundings, which has enabled the realisation of deep geological cuts, the delimitations of olytostromic units in the cuts, the division of the filling of the basin into Genetic Units or U.T.S. and the geometric characterisation of thicknesses of sandy levels for hydrogeological purposes. — Collection and updating of existing information on mineral resources, both metallic and non-metallic and industrial and ornamental rocks. — Compilation and updating of existing documentation on hydrogeology throughout the study area and the hydrogeological behavior of each of the cartographic units at 1:200,000 scale Basic mapping ensures continuity between the different leaves. Each of the sheets contains, in turn, a series of thematic layers that can constitute a single layer of information by having lateral continuity. Together with the mapping, a report of each of the sheets, which form the project, is attached, which describes the geological information contained in the geological maps, including the description of the geological units, stratigraphic, petrology, tectonics, economic geology and the tectosedimentary evolution of the corresponding area, together with a bibliography used for the writing of this report. In addition, the information resulting from geological investigations, included in an annexed database, is collected. The geological research data are composed of the results of a series of studies (absolute ages, clays, paleontology, micropaleontology, carbonate petrology, igneous rock petrology, metamorphic rock petrology, terrigen petrology, alterations and geochemistry) carried out on samples collected during the field campaigns carried out during the project. In addition to the above, there is general information about the project, not associated with the analysis of any specific sample. These are mining evidence data, gravimetric profiles, hydrology, reservoirs, stratigraphic columns and descriptive information of the project.
