Autor: Jingyao Xu, Antonio Olimpio Gonçalves, Joan Carles Melgarejo, Esperança Tauler, Salvador Martinez, Sandra Amores, Marc Campeny

Publikováno v: Clays and Clay Minerals. 67:228-243

Large kaolin deposits developed by weathering on Precambrian granitic rocks have been discovered in the Caluquembe area, Huila province, Angola. To determine accuracy of analysis and to evaluate the kaolinite grade, a full-profile Rietveld refinement
