Definition
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Origin
Japan
European Foreland Basins

Etymology
From its occurrence in the Izu-Bonin arc south of Japan
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Archaeological Significance
Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

All about Boninite and Turbidite Properties
Know all about Boninite and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Turbidite is Mud-rich, Sandy. Boninite appears Dull and Soft and Turbidite appears Dull and Banded. The luster of Boninite is vitreous while that of Turbidite is metallic. Boninite is available in bluish - grey, brown, green, grey colors whereas Turbidite is available in black, brown, green, grey, pink colors. The commercial uses of Boninite and Turbidite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
