“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.”

“If magma were to accumulate at mid-crustal levels beneath the north Taupo region, this has significant implications for hazard monitoring.”

“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.”

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

“Moreover, magnesian and hydrous magmas such as boninites and lamprophyres apparently find no difficulty in traversing the crust.”

“We propose that both shield and rejuvenescent phase magmas are derived from a lithologically heterogeneous or mantle plume.”
