Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
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

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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.

All about Conglomerate and Adakite Properties
Know all about Conglomerate and Adakite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Adakite belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Adakite is Porphyritic. Conglomerate appears Shiny and Rounded and Adakite appears Dull and Soft. The luster of Conglomerate is dull while that of Adakite is grainy, pearly and vitreous. Conglomerate and Adakite are available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Adakite are commemorative tablets, pottery, used in aquariums.
