Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
Latite 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 Hawaiite and Latite Properties
Know all about Hawaiite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Hawaiite and Latite belong to Igneous Rocks.Texture of Hawaiite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Latite is Aphanitic to Porphyritic. Hawaiite appears Dull and Soft and Latite appears Rough. The luster of Hawaiite is while that of Latite is subvitreous to dull. Hawaiite is available in black, brown, light to dark grey colors whereas Latite is available in black, brown, green, grey, pink, white colors. The commercial uses of Hawaiite are creating artwork, sea defence and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
