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.
This area hosts a band of low titanium tholeiite and boninite
mafic volcanic rocks believed to have been emplaced in high heat flow rifting environments, important for the formation of massive sulphide deposits.
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.
