Formation
Lherzolite 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.
Granophyre 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.

All about Lherzolite and Granophyre Properties
Know all about Lherzolite and Granophyre properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite and Granophyre belong to Igneous Rocks.Texture of Lherzolite is Grenue whereas that of Granophyre is Granophyric. Lherzolite appears Glassy, Vesicular and Foilated and Granophyre appears Veined or Pebbled. The luster of Lherzolite is subvitreous to dull while that of Granophyre is dull to grainy with sporadic parts pearly and vitreous. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Granophyre is available in black, grey, orange, pink, white colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums and that of Granophyre are curling, gemstone, laboratory bench tops, tombstones.
