“When magma moves beneath a volcano, such as when the magma chamber fills prior to an eruption, there is swelling of the volcanic cone above.”

“The discharge of gases causes violent explosions, which throw into space fragments of the doughy magma.”

“Variations in composition within each series reflect differentiation in magma chambers under volcanoes.”

“Prior to Cretaceous magmatism, the region underwent three major episodes of deformation.”

“Many experiments suggest that ancient subduction-related metasomatism affected OIB mantle sources long before island magmatism.”

“Both radiometric and biostratigraphic data indicate the onset of magmatism in late Mid-Jurassic time.”

“Melts of these metasomites were volatile rich and hence ascended rapidly through the lithosphere, forming the lamprophyre magmas.”

“If such adiabatic freezing were to control the ascent of hydrous mafic magmas, basalts would probably never erupt in volcanic arcs.”

“Once magmas erupt or cool beneath the surface, they are subjected to weathering and interaction with descending meteoric waters.”
