Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Formation
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.
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.
