The UTE-PLANAGEO Project (National Geology Plan of Angola). Objectives, methods...
Garcia-Lobon, Jose Luis; Merino-Martinez, Enrique; Fernández, J.; Carvalho, João; Batista, Maria Joao; Escuder, Javier; Lisboa, JoseABSTRACT: The National Geology Plan of Angola (PLANAGEO) has been one of the most important Angolan infrastructure projects throughout the past twenty years. The objectives of PLANAGEO were: (a) to enhance Angola's geological and mineral resources knowledge; (b) to foster diversification of the national economy; and, (c) to attract foreign investment and promote the country development. The project integrated r...
El Plan Nacional de Geología de Angola (PLANAGEO) [Resumo]
García-Lobón, J. L.; Merino-Martínez, E.; Rodrigues, José Feliciano; Fernández, J.; Viruete, Javier Escuder; Pereira, E.; Carvalho, JoãoRESUMEN: El Plan Nacional de Geología de Angola (PLANAGEO) ha sido uno de los proyectos geotemáticos internacionales más importantes de las últimas décadas. El proyecto fue lanzado por Gobierno de la República de Angola e implementado por el Instituto Geológico de Angola (IGEO), bajo la supervisión del Ministerio de Recursos Minerales, Petróleos y Gas (MIREMPET).

Zircon U-Pb and Lu-Hf isotopes reveal the crustal evolution of the SW Angolan S...
Ferreira, Ezequiel; Lehmann, Jeremie; Rodrigues, José Feliciano; Hayes, Ben; Merino-Martinez, Enrique; Milani, Lorenzo; Bybee, Grant M.ABSTRACT: The crustal evolution of the Angolan Shield (AS) remains poorly constrained. To address this, we analysed U-Pb and Lu-Hf isotopes in detrital and igneous zircons to investigate the age and provenance of extensive sedimentary strata in southwestern Angola and use it as a proxy to gain insight into the Archean to Mesoproterozoic evolution of the region. Mesoproterozoic maximum depositional ages for the ...
Cartografía Geológica del Plan Nacional de Geología de Angola (PLANAGEO)
Merino-Martínez, E.; Rodrigues, José Feliciano; Martín-Banda, Raquel; Francés, Alain Pascal; Feria, María Carmen; López-Bahut, T.; Ferreira, EzequielRESUMEN: La cartografía geológica fue la actividad central en la que se basó el Plan Nacional de Geología de Angola (PLANAGEO). Los trabajos de cartografía geológica realizados por el consorcio UTE PLANAGEO (IGME/LNEG/IIA) en el sur de Angola (476.512 km2), desarrollados entre 2016 y 2020, comprendieron 44 cartas a escala 1:250.000, 15 cartas a escala 100.000, 8 mapas de síntesis a escala 1:500.000 y 4 mapas ge...
Contribution of the time domain electromagnetic method to the study of the Kala...
Francés, Alain Pascal; Ramalho, Elsa; Santos, Fernando Monteiro; Llorente, J.; Mateus, T.; Martín-Banda, Raquel; Cuervo, I.; Lobón, Jose Luis GarciaABSTRACT: The Cunene Province (Southern Angola) is facing recurrent and pluriannual droughts. Surface water supply could be reinforced using the groundwater resources of the multilayered aquifer systems (MAS) hosted in the siliciclastic sediments of the Kalahari Group. The MAS were first identified in the early 2000s in Northern Namibia and recently in the Cunene Province, by studies of the PLANAGEO project bas...

Ramalho, Elsa; Francés, Alain Pascal; Martín-Banda, Raquel; Mateus, T.; Llorente, J.; Famorosa, A.; Cuervo, I.; Lobón, Jose Luis GarciaSUMMARY: Within the scope of the PLANAGEO project, the assessment of the KOS and KOH transboundary multilayered aquifer systems, located in the province of Cunene, southern Angola, without significant hydrogeological research in the last 50 years, was conducted. The drilling location of 5 deep boreholes was selected after the processing and interpretation of legacy and recently acquired geophysical data within ...

Francés, Alain Pascal; Ramalho, Elsa; Santos, Fernando Monteiro; Llorente, J.; Mateus, T.; Cuervo, I.; Lobón, Jose Luis Garcia; Dala, V.; Ditutala, M.SUMMARY: Under the scope of project PLANAGEO, a geophysical survey using the time domain electromagnetic (TDEM) method was planned and conducted. This survey aimed to contribute to the hydrogeological conceptual model of the KOS and KOH aquifer systems, to validate the 1960 data electrical resistivity reprocessing and to define the future location of deep boreholes. The TDEM survey allowed identifying different...

3D electrical structure definition of aquifer systems in the Kalahari basin in ...
Ramalho, Elsa; Francés, Alain Pascal; Santos, Fernando Monteiro; Victorino, Américo da MataABSTRACT: The Kalahari-Ohangwena transboundary aquifer system, recently identified in Northern Namibia, comprises 3 major aquifers with very different characteristics. The shallowest is discontinuous and with limited reserves, but it has local importance in water supply for the population, since it is easy to reach, and often presents good hydrochemical quality. An intermediate deeper aquifer is characterized b...
