Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Trachyandesite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Limestone vs Trachyandesite 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. Limestone vs Trachyandesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Trachyandesite. Learn more about Limestone vs Trachyandesite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Trachyandesite include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Limestone and Trachyandesite, they have various applications in construction industry. The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Trachyandesite include Building houses or walls, Cobblestones, For road aggregate, Rail track ballast, Roadstone.
More about Limestone and Trachyandesite
Here you can know more about Limestone and Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Trachyandesite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase. You can also check out the list of all Sedimentary Rocks. When we have to compare Limestone vs Trachyandesite, the texture, color and appearance plays an important role in determining the type of rock. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas, Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Limestone is Rough and Banded and that of Trachyandesite is Dull and Soft. Properties of rock is another aspect for Limestone vs Trachyandesite. The hardness of Limestone is 3-4 and that of Trachyandesite is 4-5. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Trachyandesite are Basaltic Trachyandesite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Limestone is white while that of Trachyandesite is light to dark brown. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Trachyandesite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Limestone is pressure resistant whereas Trachyandesite is heat resistant, pressure resistant, wear resistant.
