The Aeolian Volcanic District : Volcanism and Magmatism

Acta Vulcanologica : journal of the national volcanic group of Italy, 2006
The 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.

Volcanism and volcanic fluids

1977
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

Volcanic mesocyclones

Nature, 2009
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.

Volcanic Channels and Volcanic Features on Mars

2021
Volcanic channels are common features on the terrestrial planets. They have diverse morphologies including sinuous rilles, channelized flows, and potentially collapsed lava tubes. Many of these channels are a part of a typical igneous assemblage of landforms.

An Overview of the “Volcan Project”: An UAS for Exploration of Volcanic Environments

Journal of Intelligent and Robotic Systems, 2008
This paper presents an overview of the Volcan Project, whose goal is the realization of an autonomous aerial system able to perform aerial surveillance of volcanic areas and to analyze the composition of gases inside volcanic plumes. There are increasing experimental evidences that measuring the chemical composition of volcanic gases can contribute to ...
