Servicio Geológico de Argentina (SEGEMAR) is the national geological survey of Argentina responsible for geological mapping, stratigraphic research, mineral resource assessment and geohazard evaluation. It operates within the Argentine public administration and interfaces with provincial agencies, international scientific bodies and extractive industry stakeholders. SEGEMAR produces data sets, technical reports and maps that inform policy, exploration and academic research across Argentina and the Southern Cone.
SEGEMAR traces institutional origins to early 20th-century initiatives linked to the Universidad de Buenos Aires, the Museo de La Plata, the Dirección General de Minas y Geología and regional mining commissions in the Patagonia. Its formalization paralleled activities of figures associated with the Sociedad Geológica Argentina and contemporaneous surveys in Chile, Peru and Bolivia. Throughout the 20th century SEGEMAR collaborated with research programs of the Consejo Nacional de Investigaciones Científicas y Técnicas, participated in continental projects with the Servicio Geológico Colombiano and adapted to policy shifts during administrations of Juan Perón and subsequent Argentine governments. In recent decades SEGEMAR engaged in initiatives with the United States Geological Survey, the International Union of Geological Sciences and regional programs tied to energy development in the Neuquén Basin and mineral exploration in the Puna de Atacama.
SEGEMAR is organized into technical divisions that coordinate with federal ministries, provincial directorates and academic partners such as the Universidad Nacional de La Plata and the Universidad Nacional de San Juan. Its governance framework references regulations enacted by the Ministerio de Economía and interfaces with the Agencia Nacional de Promoción Científica y Tecnológica for research funding. Administrative oversight has involved appointments traceable to cabinets of presidents including Raúl Alfonsín and Cristina Fernández de Kirchner, while advisory ties extend to committees involving representatives from the Cámara Argentina de Empresarios Mineros and regional authorities from Mendoza Province and Salta Province.
SEGEMAR conducts mineral resource assessments for commodities such as copper, lithium, gold and silver in regions like the Andes, the Sierras Pampeanas and the Valle del Río Negro. It evaluates geohazards including seismic risk in areas influenced by the Nazca Plate subduction, volcanic hazards associated with the Andean Volcanic Belt and landslide susceptibility in the Yungas. The agency provides technical support for petroleum exploration in basins such as the Neuquén Basin, carbon storage studies tied to the Vaca Muerta play, and groundwater studies in the Mesopotamia region. SEGEMAR issues geological hazard alerts that complement monitoring by institutions like the Instituto Nacional de Prevención Sísmica and contributes to environmental impact assessments for projects reviewed by the Secretaría de Ambiente y Desarrollo Sustentable.
SEGEMAR maintains national-scale geological mapping programs, digital cartography libraries and borehole databases used by prospectors, planners and researchers from organizations like the Sociedad Geológica del Perú and the Geological Society of America. Its data products include 1:1,000,000 and 1:250,000 maps covering provinces such as Santa Cruz Province, Jujuy Province and Tierra del Fuego Province. SEGEMAR collaborates on geospatial standards with the Instituto Geográfico Nacional and contributes to continental compilations coordinated by the Pan American Institute of Geography and History. Open data initiatives link SEGEMAR datasets with international portals maintained by the World Data System and scientific consortia focused on stratigraphy, paleontology and mineral resources.
SEGEMAR publishes technical reports, bulletins and monographs that document stratigraphic frameworks, metallogeny and tectonic evolution of regions including the Famatina Range and the Sierra de la Ventana. Its research outputs are cited alongside works from the University of Buenos Aires faculty, papers in the Journal of South American Earth Sciences and conference proceedings of the Latin American Geophysical Union. SEGEMAR scientists have contributed to studies on orogeny, basin analysis and isotope geochemistry, collaborating with laboratories at the Oak Ridge National Laboratory and European institutions such as the University of Oxford and the Université de Genève.
SEGEMAR operates laboratories for petrography, geochemistry and paleontology, field stations in provinces like Chubut and La Rioja, and core repositories that serve mining companies and universities including the Universidad Nacional del Comahue. It maintains seismic monitoring arrays in partnership with the Red Sismográfica Nacional and sample archives used by researchers from institutions such as the Max Planck Institute for Chemistry and the Smithsonian Institution. SEGEMAR's cartographic and bibliographic collections are housed in facilities in Buenos Aires and regional centers co-located with provincial geological services.
SEGEMAR engages in bilateral and multilateral cooperation with entities including the United States Geological Survey, the Geological Survey of Canada and the European Commission through research programs and capacity-building workshops. It hosts training for geoscientists in collaboration with universities like the Massachusetts Institute of Technology and regional education initiatives supported by the Organization of American States. SEGEMAR participates in international assessments by the International Atomic Energy Agency on radiometric methods and contributes expertise to transboundary projects addressing water resources, biodiversity impacts and sustainable mining in corridors shared with Chile and Bolivia.
