Formation
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Trachyte vs Claystone 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. Trachyte vs Claystone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Trachyte and Properties of Claystone. Learn more about Trachyte vs Claystone in the next section. The interior uses of Trachyte include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Trachyte and Claystone, they have various applications in construction industry. The uses of Trachyte in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Claystone include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Trachyte and Claystone
Here you can know more about Trachyte and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Trachyte and Claystone consists of mineral content and compound content. The mineral content of Trachyte includes Augite, Biotite, Feldspar, Hornblade, Plagioclase, Quartz and mineral content of Claystone 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 Trachyte vs Claystone, the texture, color and appearance plays an important role in determining the type of rock. Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors whereas, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Trachyte is Banded and that of Claystone is Rough and Dull. Properties of rock is another aspect for Trachyte vs Claystone. The hardness of Trachyte is 6 and that of Claystone is 3.5-4. The types of Trachyte are Not Available whereas types of Claystone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Trachyte and Claystone is white. The specific heat capacity of Trachyte is Not Available and that of Claystone 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.Trachyte is heat resistant, impact resistant, wear resistant whereas Claystone is heat resistant, impact resistant.
