Definition
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles

Features
Has High structural resistance against erosion and climate, Host rock for Diamond, Very fine grained rock

Archaeological Significance
Formation
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.
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.

More about Adakite and Turbidite
Here you can know more about Adakite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adakite and Turbidite consists of mineral content and compound content. The mineral content of Adakite includes Olivine, Plagioclase, Pyroxene and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Adakite vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Adakite is available in black, brown, light to dark grey colors whereas, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Adakite is Dull and Soft and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Adakite vs Turbidite. The hardness of Adakite is 3-4 and that of Turbidite is 3. The types of Adakite are Intermediate volcanic rock whereas types of Turbidite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adakite is bluish black while that of Turbidite is white, greenish white or grey. The specific heat capacity of Adakite is 0.84 kJ/Kg K and that of Turbidite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Adakite is heat resistant, pressure resistant, wear resistant whereas Turbidite is heat resistant.
