Definition
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals
  
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

Formation
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
  
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.

Syenite vs Mudstone Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Syenite vs Mudstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Syenite and Properties of Mudstone. Learn more about Syenite vs Mudstone in the next section. The interior uses of Syenite include Flooring, Homes, Hotels and Interior decoration whereas the interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration. Due to some exceptional properties of Syenite and Mudstone, they have various applications in construction industry. The uses of Syenite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Mudstone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Syenite and Mudstone
Here you can know more about Syenite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Syenite and Mudstone consists of mineral content and compound content. The mineral content of Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Syenite vs Mudstone, the texture, color and appearance plays an important role in determining the type of rock. Syenite is available in brown, buff, cream, green, grey, pink, white colors whereas, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Syenite is Banded and Foilated and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Syenite vs Mudstone. The hardness of Syenite is 5.5-6 and that of Mudstone is 2-3. The types of Syenite are Shonkinite whereas types of Mudstone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Syenite and Mudstone is white. The specific heat capacity of Syenite is 0.92 kJ/Kg K and that of Mudstone is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Syenite is heat resistant, impact resistant, wear resistant whereas Mudstone is heat resistant, impact resistant.
