Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Archaeological Significance
Formation
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.
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.

All about Latite and Lignite Properties
Know all about Latite and Lignite properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Lignite belongs to Sedimentary Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Lignite is Amorphous, Glassy. Latite appears Rough and Lignite appears Veined or Pebbled. The luster of Latite is subvitreous to dull while that of Lignite is dull to vitreous to submetallic. Latite is available in black, brown, green, grey, pink, white colors whereas Lignite is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo) and that of Lignite are electricity generation.
