The Alfragide core library contains about 260,000 m of core from 808 drill holes related with the exploration of hydrocarbons in the Meso-Cenozoic Basins, metallic and non-metallic mineral resources, from both the Meso-Cenozoic Basins and the Northern Alentejo, and hydrogeology from the Northern Alentejo. Alfragide is also home to several collections of samples from geological reconnaissance campaigns carried out in the Portuguese-speaking African countries (Angola, Mozambique, São Tomé and Príncipe, Cape Verde, Guinea Bissau, among others), including those from the extinct Institute of Tropical Scientific Research, and collections of fossils, rocks and minerals, belonging to the collection of the Geological Services Museum.
