Boninite and Trachyte
Definition
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
Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar

Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

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