Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
Sovites are formed due to low degrees of partial melting of rocks.

All about Hawaiite and Sovite Properties
Know all about Hawaiite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Hawaiite and Sovite belong to Igneous Rocks.Texture of Hawaiite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Sovite is Granular, Poikiloblastic. Hawaiite appears Dull and Soft and Sovite appears Dull, Banded and Foilated. The luster of Hawaiite is not available while that of Sovite is subvitreous to dull. Hawaiite is available in black, brown, light to dark grey colors whereas Sovite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Hawaiite are creating artwork, sea defence and that of Sovite are an oil and gas reservoir, as a feed additive for livestock, creating artwork, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
