Definition
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Hawaiite and Serpentinite Properties
Know all about Hawaiite and Serpentinite properties here. All properties of rocks are important as they define the type of rock and its application. Hawaiite belongs to Igneous Rocks while Serpentinite belongs to Metamorphic Rocks.Texture of Hawaiite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Serpentinite is Earthy. Hawaiite appears Dull and Soft and Serpentinite appears Rough and Dull. The luster of Hawaiite is not available while that of Serpentinite is waxy and dull. Hawaiite is available in black, brown, light to dark grey colors whereas Serpentinite is available in black, brown, colourless, green, grey, white colors. The commercial uses of Hawaiite are creating artwork, sea defence and that of Serpentinite are commemorative tablets, creating artwork.
