Pre-Mesoproterozoic crustal framework and Mesoproterozoic evolution of the SW A...
Merino-Martínez, E.; Ferreira, Ezequiel; Valverde-Vaquero, Pablo; Rodrigues, José Feliciano; Escuder-Viruete, Javier; Garcia-Lobon, Jose LuisABSTRACT: The southwestern Angolan Shield hosts the Earth's largest Mesoproterozoic massif-type anorthosite complex (up to 53,500 km(2)), the Kunene Complex (KC). This complex is the result of a long-lived (similar to 200 Ma) episodic emplacement of coalescent magmatic pulses. The recent acquisition of multidisciplinary data during the PLANAGEO project has significantly enhanced our understanding of the Precamb...
Pre-Mesoproterozoic crustal architecture and implications for the Mesoproterozo...
Merino-Martínez, E.; Ferreira, Ezequiel; Valverde-Vaquero, Pablo; Rodrigues, José Feliciano; Escuder-Viruete, Javier; Garcia-Lobon, Jose LuisABSTRACT: Several studies suggest the existence of multiple tectonic domains within the Angolan Shield [1], yet the Archaean to Palaeoproterozoic basement of SW Angola and NW Namibia remains largely unexplored. Similarly, distinct Mesoproterozoic (1534–1065 Ma) igneous suites are documented in the SW Angolan Shield, including the largest known gabbro-anorthosite complex (~42,500 km²), the Kunene Complex (KC), b...
Serie cartográfica de Rocas y Minerales Industriales de Angola: Resultados del ...
Fernández, J.; Lisboa, Jose; Iglesias-Martínez, M.; Gumiel, J.C.; Feria, María Carmen; Francés, Alain Pascal; Merino-Martínez, E.; Manuel, JoséRESUMEN: El Gobierno de la República de Angola, consciente de la importancia del sector de las rocas y minerales industriales en el desarrollo socioeconómico de su territorio, evitando la dependencia de la minería metálica, energética y diamantífera, ha promovido la realización una nueva serie cartográfica en el ámbito del subprograma CARMINA, dentro del Proyecto PLANAGEO (Plan Nacional de Geología) para elabor...
Exploración regional con analizadores portátiles de fluorescencia de rayos X (F...
Martín-Méndez, I.; Merino-Martínez, E.; Batista, Maria Joao; Feria, María Carmen; Prazeres, Cátia; Gumiel, J.C.; Iglesias-Martinez, M.; Fernández, J.RESUMEN: Durante el Proyecto PLANAGEO se llevó a cabo una importante campaña de exploración geoquímica en la región de Giraúl. Los trabajos geoquímicos regionales han consistido en el análisis in situ de muestras de rocas, suelos y sedimentos de corriente mediante analizadores portátiles de fluorescencia de rayos X (FRXp), centrándose en la zona del Campo Pegmatítico de Giraúl, uno de los campos pegmatíticos má...
Remote sensing applied to litho-structural and regolith mapping of the SW of An...
Gumiel, J.C.; López-Bahut, T.; Martín-Banda, Raquel; Quental, LídiaABSTRACT: IGEO (Geological Institute of Angola) has developed the sosubprograms was focused on the remote sensing survey of the country. The main objective of the study is the use of satellite Earth Observation data in order to support preliminary geological and regolith mapping. This allows us to obtain a first approximation to cartography 1:250.000. Litho-structural and regolith maps are elaborated over eight...
