| dc.description.abstract | RESUMEN: Los mapas de recursos minerales a escala 1:50.000 fueron realizados en la Ćŗltima fase del Proyecto PLANAGEO con el objetivo de evaluar el potencial mineral de la regiĆ³n sur de Angola. Los objetivos elegidos fueron, entre otros, las zonas que contienen Au-Fe en las Ć”reas de Jamba-Cassinga-Tchamutete, Chipindo y Cuima-Samboto. Los mapas integraron mapas geolĆ³gicos, datos magnĆ©ticos y radiomĆ©tricos aĆ©reos y resultados de FRXp de campaƱas de campo de PLANAGEO y yacimientos minerales conocidos. Se obtuvieron anĆ”lisis univariantes, bivariantes y multivariantes y grupos de pathfinders, tales como: Factor 1 (F1)- Cd, Hg, Fe2O3, As, V, Ni de rocas en Chipindo o Factor 1(F1) - Fe2O3, As, Sn, Sb, Ta en rocas de Jamba. Esos grupos fueron identificados como pathfinders de Au, representados en los Mapas de Potencial por encima del percentil 80. En el caso de Jamba era >0,838 y el Ć”rea delimitada incluĆa rocas BIF, rocas metavolcĆ”nicas bimodales del terreno Arcaico del Grupo Jamba. | pt_PT |
| dc.description.abstract | ABSTRACT: The mineral resources maps at 1:50.000 scale were made in the last phase of PLANAGEO Project with the objective of increasing mineral potential of Southern Angola. The targets chosen were the brownfields areas containing Au-Fe in Jamba-Cassinga-Tchamutete, Chipindo and Cuima-Samboto areas. The maps were produced by integrating the geological maps, airborne magnetic and radiometric data and pXRF results from PLANAGEOĀ“s field campaigns and known mineral occurrences. Univariate, bivariate and multivariate analysis were obtained and groups of pathfinders, such as: Factor 1 (F1)- Cd, Hg, Fe2O3, As, V, Ni from rocks in Chipindo or Factor 1(F1) - Fe2O3, As, Sn, Sb, Ta in rocks of the Jamba area. Those groups of elements were identified as Au pathfinders, represented in the Potential Maps above the 80th percentile, in the case of Jamba was >0.838 and the delimited area included BIF rocks, bimodal metavolcanic rocks of the Archean terrain of Jamba Group. | pt_PT |
