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
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Hyaloclastite and Quartzite Properties
Know all about Hyaloclastite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Hyaloclastite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Hyaloclastite is Pyroclastic whereas that of Quartzite is Foliated, Granular. Hyaloclastite appears Dull and Quartzite appears Lustrous. The luster of Hyaloclastite is dull and grainy while that of Quartzite is vitreous. Hyaloclastite is available in brown, grey, yellow colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Hyaloclastite are cemetery markers, creating artwork and that of Quartzite are an oil and gas reservoir, as armour rock for sea walls, cemetery markers, commemorative tablets, in aquifers, laboratory bench tops, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
