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

Archaeological Significance
Formation
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.

More about Boninite and Trachyte
Here you can know more about Boninite and Trachyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Trachyte consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Trachyte includes Augite, Biotite, Feldspar, Hornblade, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Trachyte, the texture, color and appearance plays an important role in determining the type of rock. Boninite is available in bluish - grey, brown, green, grey colors whereas, Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors. Appearance of Boninite is Dull and Soft and that of Trachyte is Banded. Properties of rock is another aspect for Boninite vs Trachyte. The hardness of Boninite is 7 and that of Trachyte is 6. The types of Boninite are Basalt whereas types of Trachyte are Felsic volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Boninite and Trachyte is white. The specific heat capacity of Boninite is 0.84 kJ/Kg K and that of Trachyte is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Boninite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Trachyte is heat resistant, impact resistant, wear resistant.
