Monogenetic volcanic field

A monogenetic volcanic field is a volcanic field of little, dotted volcanic vents. are noted for having only one small eruptive event at each volcano, as opposite to regular volcanoes that have more than a small number of eruptions from the same vent in excess of a long period in their history, Mount Vesuvius being an example. Monogenetic fields happen only where the magma provides to the volcano is low or where vents are not close sufficient or large sufficient to expand plumbing systems for incessant feeding of magma. Monogenetic volcanic fields can give snapshots of the fundamental region beneath the surface, and may be helpful in studying the generation of magma and the work of art of the layer since the single eruption produced would competition that of the chamber it erupted from.

Some types of volcanoes include cinder cones, shield volcanoes, tuff cones and maars.

Examples of monogenetic volcanic fields:

* Auckland volcanic field, fundamental much of the city of Auckland, New Zealand and its suburbs
* Wells Gray-Clearwater volcanic field, east-central British Columbia, Canada.
* Parícutin, Michoacán, Mexico
