Definition
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment
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
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
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 Hyaloclastite and Adakite Properties
Know all about Hyaloclastite and Adakite properties here. All properties of rocks are important as they define the type of rock and its application. Hyaloclastite and Adakite belong to Igneous Rocks.Texture of Hyaloclastite is Pyroclastic whereas that of Adakite is Porphyritic. Hyaloclastite appears Dull and Adakite appears Dull and Soft. The luster of Hyaloclastite is dull and grainy while that of Adakite is grainy, pearly and vitreous. Hyaloclastite is available in brown, grey, yellow colors whereas Adakite is available in black, brown, light to dark grey colors. The commercial uses of Hyaloclastite are cemetery markers, creating artwork and that of Adakite are commemorative tablets, pottery, used in aquariums.
