Definition
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

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