Volcanological constraints of Archaean tectonics [PDF]

open access: yes
Volcanological and trace element geochemical data can be integrated to place some constraints upon the size, character and evolutionary history of Archean volcanic plumbing, and hence indirectly, Archean tectonics.

Eruption dynamics of cyclic vulcanian explosions from Galeras volcano, Colombia

open access: yes, 2019
Extended periods of volcanic unrest characterised by repeated, or cyclical, vulcanian explosions are common at arc volcanoes worldwide. Such explosions are thought to occur following the emplacement of a dense, degassed, lowper-meability plug of highly crystalline and highly viscous magma in the shallow conduit. Despite advances in the understanding of
