Definition
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.

Formation
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

More about Mudstone and Ganister
Here you can know more about Mudstone and Ganister. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Ganister consists of mineral content and compound content. The mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all . When we have to compare Mudstone vs Ganister, the texture, color and appearance plays an important role in determining the type of rock. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Mudstone is Rough and Dull and that of Ganister is Rough. Properties of rock is another aspect for Mudstone vs Ganister. The hardness of Mudstone is 2-3 and that of Ganister is 6-7. The types of Mudstone are Marl, Shale and Argillite whereas types of Ganister are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone and Ganister is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Ganister is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Mudstone is heat resistant, impact resistant whereas Ganister is heat resistant, impact resistant, pressure resistant.
