This paper gives a review of the work dealing with the petrology and petrogenesis of the active volcano Mt. Nyiragongo in the eastern part of Congo. The volcano has been drilled through an essentially granitic Pre-Cambrian substratum. The rocks represent melilitite (bergalite) tuffs and lavas overlain by leucitites and, on top of the mountain, by nephelinites. The volcano is the only one known so far in which extrusive and effusive bergalitic materials play an important role. The various rock… Expand

Petrology and geochemistry of the Nyamuragira volcano, Zaire
Abstract Nyamuragira volcano in the Western Rift of the East Africa Rift Valley is characterized by violent volcanic eruptions, the most recent of which occurred in 1967, 1971, 1976–1977, 1980 andExpand
Nyiragongo and Nyamuragira: a review of volcanic activity in the Kivu rift, western branch of the East African Rift System
Nyiragongo and Nyamuragira are two active volcanoes of the Western branch of the East African Rift in the Virunga area. They were built at the Kivu rift axis ca. 12,000 years ago and set above twoExpand

The origin of ultramafic and ultrabasic rocks
Ultramafic rocks are classified in terms of their field associations and tectonic environment. Eleven associations are distinguished, some with subdivisions. The major features of each associationExpand
Mineral chemistry and petrogenesis of an ultrapotassic-ultramafic volcanic rock
AbstractCompositions of the major phenocryst minerals (olivine, phlogopite) and groundmass minerals (olivine, phlogopite, kalsilite), and a glass phase have been determined from a biotite mafuriteExpand
In igneous rocks the occurrence of such mineral pairs as leucite and sanidine, or nepheline and albite indicates that silica activity may be buffered over a range of temperatures. Using publishedExpand
Mt. Niragongo: renewed activity of the lava lake
Abstract On the 21st of June, 1982, Mt. Niragongo ended a period of dormancy that had begun on January 11, 1977, and fresh lava began to flow into the 800-m-deep crater. On October 3, a huge lavaExpand
