5 Formation

5.1 Formation

Hornblendite 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 Hornblendite and Quartzite Properties

Know all about Hornblendite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Hornblendite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Hornblendite is Banded, Foliated, Massive whereas that of Quartzite is Foliated, Granular. Hornblendite appears Foliated and Quartzite appears Lustrous. The luster of Hornblendite is vitreous to dull while that of Quartzite is vitreous. Hornblendite is available in black, brown, green, grey colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Hornblendite are cemetery markers, commemorative tablets, 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.
