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

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.

All about Adakite and Turbidite Properties
Know all about Adakite and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Adakite belongs to Igneous Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Adakite is Porphyritic whereas that of Turbidite is Mud-rich, Sandy. Adakite appears Dull and Soft and Turbidite appears Dull and Banded. The luster of Adakite is grainy, pearly and vitreous while that of Turbidite is metallic. Adakite is available in black, brown, light to dark grey colors whereas Turbidite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Adakite are commemorative tablets, pottery, used in aquariums and that of Turbidite are cemetery markers, creating artwork.
