Resum
Remains of carbonatitic volcanic buildings are located near the village of Catanda (Kwanza Sul, Angola). These volcanic carbonatites occupy an area of 50 Km2 forming small and eroded edifices mostly covered by quaternary sediments and hosted in Archaean granites. The age of the Catanda volcanic activity is not precisely calculated although Silva and Pereira (1973) proposed an approximated age of 92 ( ± 7 m.y). Pyroclastic rocks form the most important deposits in the area with typical sequences...
