Abstract
The Niragongo volcano of the Congo region is located in the western Great Rift Valley in east Africa. The cone is formed of feldspathoidal lavas containing augite and accessory minerals, and the crater contains terraces representing ancient lava levels. Studies were conducted on the chemical composition and petrography of the rocks, on the chemistry of the gases and sublimates, and on the temperature of the lavas. The magnetic and gravimetric values for the volcano and the area were measured and energy discharge was estimated. The study confirmed the importance of the gaseous phase in volcanic phenomena.Keywords
