Clague, D.A. and Dixon, J.E. (2000). Extrinsic controls on the evolution of Hawaiian ocean island volcanoes. Geochemistry Geophysics Geosystems 1: doi: 10.1029/1999GC000023. issn: 1525-2027.

Extrinsic parameters that affect the evolution of magmatic systems within and beneath ocean island volcanoes include physical variables such as confining pressure, which controls magma degassing, and temperature of the underlying lithosphere and crust, which controls magma crystallization during ascent. Other extrinsic parameters are environmental variables coupled to the hydrosphere and atmosphere such as hydrothermal circulation systems and even rainfall. All these extrinsic factors interact with intrinsic parameters, such as magma supply rates or composition, to modulate the evolution of magma chambers and the petrologic processes that take place within them.
