Formation
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.

More about Lignite and Breccia
Here you can know more about Lignite and Breccia. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Breccia consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Breccia includes Calcite, Clay, Feldspar, Phosphates, Quartz, Silica. You can also check out the list of all . When we have to compare Lignite vs Breccia, the texture, color and appearance plays an important role in determining the type of rock. Lignite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors. Appearance of Lignite is Veined or Pebbled and that of Breccia is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Lignite vs Breccia. The hardness of Lignite is 1 and that of Breccia is 7. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Breccia are Collapse Breccia, Fault Breccia, Flow Breccia, Pyroclastic Breccia, Igneous Breccia and Impact Breccia. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lignite is black while that of Breccia is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Breccia is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Lignite is heat resistant whereas Breccia is heat resistant, impact resistant, pressure resistant, wear resistant.
