	Monogenetic volcanic field - Wikipedia, the free encyclopedia
		Monogenetic volcanic fields are areas of scattered volcanic vents; so that roughly speaking a monogenetic field is a type of volcano.
		Monogenetic fields can only occur where the magma supply to the volcano is very low.

	Auckland volcanoes
		Volcanic activity from an eruption at a site within the Auckland volcanic field could produce serious problems in the day to day existence for those who live in the Auckland region and for New Zealanders supported by Auckland’s business and industry.
		Knowledge of the type and effects of volcanic activity are based on studies of volcanic deposits in the Auckland area and on analogues of similar eruptions from similar types of volcanoes elsewhere in the world.
		Although volcanic earthquakes rarely exceed an intensity of 8 on the Modified Mercalli Scale (this scale is based on the felt intensity of an earthquake and is different from the Richter scale based on the amount of energy released), they would be destructive if an eruption occurred in or near a built up area.

	Journal of the Geological Society: Compositional variation during monogenetic volcano growth and its implications for ...
		We conclude that the two studied continental monogenetic volcanic fields demonstrate a consistent history of early magmatic injections that fail to reach the surface, followed by capture and partial eruption of their evolved residues in the course of separate and significantly later injections of basanite that extend to the surface and erupt.
		Monogenetic volcanoes are small and occur as scoria cones, tuff cones and rings, and maars; they form from single, typically brief eruptions (Walker 1993).
		In this study, remnants of 55 volcanoes of the Waipiata volcanic field were examined (Nemeth 2001), some 75% of which comprise glassy pyroclastic rocks intruded by dykes and sills, and/or overlain by lavas.

		Monogenetic fields also don't look like "volcanoes", rather they are collections of sometimes hundreds to thousands of separate vents and flows.
		Monogenetic fields are the result of very low supply rates of magma.
		A monogenetic field is kind of like taking a single volcano and spreading all its separate eruptions over a large area.

		Phreatomagmatic volcanism at the Waipiata Volcanic Field, Otago, New Zealand (abstract in pdf).
		The major volcanism associated with the crustal extension occurs about 120 km to the east of the Alpine Fault, with minor alkaline volcanism immediately to the east of the Alpine Fault, and with no volcanism between the two areas.
		Volcanic eruptions took place in late Miocene area with strong relief (valleys and ridges) along hydrologically active zones, producing widespread phreatomagmatic maar/diatreme volcanism with extensive Strombolian scoria cone and lava flow forming eruptions.

	RECURRENCE RATES OF VOLCANISM IN BASALTIC VOLCANIC FIELDS: AN EXAMPLE FROM THE SPRINGERVILLE VOLCANIC FIELD, AZ, USA
		Models of volcanism recurrence rate are used to evaluate long-term volcanic hazards and to suggest mechanisms for the formation of volcanic fields (Bacon, 1982; Kuntz and others, 1986; Ho, 1992; McBirney, 1992; Wadge and others, 1994; Connor and Hill, 1995).
		The model is used to track the Plio-Quaternary development of this large Colorado Plateau volcanic field (Figure 1) and to quantify the relationship between rate of vent formation, volume measured as magma output rate, and changes in the major petrologic characteristics of basalts.
		This pattern is clear in the eastern portion of the field at 1.0 Ma (Figure 12c) and the western and central portions of the field at 0.75 Ma (Figure 12d).

		The explosivity that characterizes prehistoric and recent volcanism in the region is enhanced by the area's proximity to sea level and high water table, which results in powerful phreatomagmatic eruptions.
		The intricate tectonic fabric of Luzon Island is expressed as a mosaic of roughly parallel mountain ranges, sedimentary basins, volcanic chains, allochtonous terranes, and Cretaceous to Cenozoic magmatic and metamorphic belts.
		Volcanism along the Bataan-Mindoro arc commenced about 15 Ma (De Boer and others, 1980; Defant and others, 1988) after the initiation of subduction of the South China Sea crust along the Manila Trench (Cardwell and others, 1980; Hayes and Lewis, 1984).

		According to geochemical studies of the alkali basalts from the Bakony-Balaton Highland Volcanic Field (Embey-Isztin et al., 1993), the magmas rose to the surface quickly, without remarkable crustal contamination, thus their geochemical features are indicative of the source region in the mantle.
