Definition
Litchfieldite is a rare igneous rock which is coarse-grained, foliated and a variety of nepheline syenite, sometimes also called as nepheline syenite gneiss or gneissic nepeheline syenite
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite

Formation
Litchfieldite 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.
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.

All about Litchfieldite and Hawaiite Properties
Know all about Litchfieldite and Hawaiite properties here. All properties of rocks are important as they define the type of rock and its application. Litchfieldite and Hawaiite belong to Igneous Rocks.Texture of Litchfieldite is Granular whereas that of Hawaiite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Litchfieldite appears Banded and Foilated and Hawaiite appears Dull and Soft. The luster of Litchfieldite is greasy to dull while that of Hawaiite is not available. Litchfieldite is available in brown, buff, cream, green, grey, pink, white colors whereas Hawaiite is available in black, brown, light to dark grey colors. The commercial uses of Litchfieldite are creating artwork and that of Hawaiite are creating artwork, sea defence.
