Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

All about Hawaiite and Peridotite Properties
Know all about Hawaiite and Peridotite properties here. All properties of rocks are important as they define the type of rock and its application. Hawaiite and Peridotite belong to Igneous Rocks.Texture of Hawaiite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Peridotite is Phaneritic. Hawaiite appears Dull and Soft and Peridotite appears Rough and Shiny. The luster of Hawaiite is while that of Peridotite is shiny. Hawaiite is available in black, brown, light to dark grey colors whereas Peridotite is available in dark greenish - grey colors. The commercial uses of Hawaiite are creating artwork, sea defence and that of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
