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
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture

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.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Adakite and Latite
Here you can know more about Adakite and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adakite and Latite consists of mineral content and compound content. The mineral content of Adakite includes Olivine, Plagioclase, Pyroxene and mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Adakite vs Latite, 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, Latite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Adakite is Dull and Soft and that of Latite is Rough. Properties of rock is another aspect for Adakite vs Latite. The hardness of Adakite is 3-4 and that of Latite is 5-5.5.
