Definition
Icelandite belongs to volcanic igneous rocks which is rich in iron and belongs to andesite rock
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation
Icelandite 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.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Icelandite and Quartzite Properties
Know all about Icelandite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Icelandite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Icelandite is Aphanitic to Porphyritic whereas that of Quartzite is Foliated, Granular. Icelandite appears Dull and Soft and Quartzite appears Lustrous. The luster of Icelandite and Quartzite is vitreous. Icelandite is available in bluish - grey, grey, pink, yellow colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Icelandite 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.
