Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite

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.
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.

All about Lherzolite and Hawaiite Properties
Know all about Lherzolite and Hawaiite properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite and Hawaiite belong to Igneous Rocks.Texture of Lherzolite is Grenue whereas that of Hawaiite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Lherzolite appears Glassy, Vesicular and Foilated and Hawaiite appears Dull and Soft. The luster of Lherzolite is subvitreous to dull while that of Hawaiite is not available. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Hawaiite is available in black, brown, light to dark grey colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums and that of Hawaiite are creating artwork, sea defence.
