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
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

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.
Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

More about Litchfieldite and Lignite
Here you can know more about Litchfieldite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Litchfieldite and Lignite consists of mineral content and compound content. The mineral content of Litchfieldite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite and mineral content of Lignite is not available. You can also check out the list of all Igneous Rocks. When we have to compare Litchfieldite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Litchfieldite is available in brown, buff, cream, green, grey, pink, white colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Litchfieldite is Banded and Foilated and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Litchfieldite vs Lignite. The hardness of Litchfieldite is 5.5-6 and that of Lignite is 1. The types of Litchfieldite are Borolanite and Litchfieldite whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Litchfieldite is white while that of Lignite is black. The specific heat capacity of Litchfieldite is Not Available and that of Lignite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Litchfieldite is heat resistant, impact resistant, wear resistant whereas Lignite is heat resistant.
