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
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth

Etymology
From its occurrence at Litchfield, Maine, USA
From Late Latin Basaltes (variant of basanites ), very hard stone, which was imported from Ancient Greek Basanites

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.
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

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