A strong volcanic plume consists of a vertical column of hot gases and dust topped with a horizontal 'umbrella'. The column rises, buoyed by entrained and heated ambient air, reaches the neutral-buoyancy level, then spreads radially to form the umbrella.

It is only in volcanic processes that we directly experience magmatism and the fluid emanations of magmas. Consequently, it is of the greatest importance to petrology to extrapolate what we learn from these processes to the fossil products of magmatism in geologic deposits. Yet volcanism differs greatly from plutonism, and its products usually bear the

The Aeolian Volcanic District : Volcanism and Magmatism
Acta Vulcanologica : journal of the national volcanic group of Italy, 2006The Aeolian Volcanic District is a geologically complex region characterised by a wide spectrum of volcanism and compositionally variable magmatism younger than 1-1.3 Ma. Submarine and subaerial volcanic activities formed seven large strato-volcanoes, that upraise from ~1500-2000 m b.s.l., and several seamounts.

Volcanic (Volcanic-Plutonic) Belts
1971In recent years, after the works of Ustiev and his co-workers [Ustiev, 1959, 19631, 19632, 1965; Speranskaya, 1961] on the study of the Okhotsk volcanic belt, this type of structure has gained considerable attention. The distinctive character of vulcanism, its superposition on older structural plans and its apparent independence of geosynclines, has ...

Volcanic Edifices and Volcanic Deposits
2004Young volcanoes contrast with most other mountains by forming lovely cones or impressive edifices sometimes rising high above their surroundings. Even small volcanoes, which almost always occur in groups, greatly enhance the attraction of an otherwise morphologically bland landscape.
