This ophiolite includes magmas from MORB to Boninite
and suggest that it was formed in an arc/back arc system.
1998) hypothesized an arc setting for the boninite series rocks from this belt of Canada.
1998): Boninite series: low Ti-tholeiite associations from the 2.
Rocks snatched from the volcano include boninite
lavas, a chemically distinct type of lava previously found only around extinct volcanoes that erupted more than 1 million years ago.
The West Mata Volcano is producing boninite
lavas, believed to be among the hottest on Earth in modern times, and a type seen before only on extinct volcanoes more than one million years old.
1989) Geological setting, petrology and geochemistry of Cambrian boninite
and low-Ti tholeiite lavas in western Tasmania.
Swarms of these dikes are exposed in the Bonin Islands, and one lava type from this environment, boninite
, was named for the islands.
Subsequently Stern and Bloomer (1992) established a link between initiation of subduction, boninite
production and ophiolite formation.
petrogenesis: chemical and Nd-Sr isotopic constraints: Earth and Planetary Science Letters, v.
Geochemical analyses show that the schist is a high-Ca boninite
(high-Mg andesite to basalt).
Because some Archean komatiites are associated with calc-alkaline volcanic rocks and boninites
, Grove and Parman (2004) argued that like recent boninites
, komatiites may result from wet melting above a subduction zone.
