Resum
Carbonatitic lavas and pyroclastic rocks are exposed in the volcanic area of Catanda representing the only example of extrusive carbonatites in Angola. A new detailed geological map of the area is presented in this study as well as six different stratigraphic sections formed by carbonatitic pyroclastic rocks and lava flows. Carbonatitic lavas outcrop in the SE part of the Catanda area, forming massive layers interbedded within pyroclastic materials. At least 4 different types of carbonatitic lav...
