Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat
From French, Latin lignum wood + -ite1
Coarse Grained Rock, Fine Grained Rock, Medium Grained Rock, Opaque Rock
Black, Brown, Dark Brown, Grey, Light to Dark Grey
for Road Aggregate, Steel Production
Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite
Generally rough to touch, Helps in production of Heat and Electricity, Used as fossil fuel
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.

Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.
