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
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

All about Adakite and Marble Properties
Know all about Adakite and Marble properties here. All properties of rocks are important as they define the type of rock and its application. Adakite belongs to Igneous Rocks while Marble belongs to Metamorphic Rocks.Texture of Adakite is Porphyritic whereas that of Marble is Granular. Adakite appears Dull and Soft and Marble appears Veined and Shiny. The luster of Adakite is grainy, pearly and vitreous while that of Marble is dull to pearly to subvitreous. Adakite is available in black, brown, light to dark grey colors whereas Marble is available in black, blue, brown, grey, pink, white colors.
