Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

Limestone vs Rhyolite 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 Rhyolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Rhyolite. Learn more about Limestone vs Rhyolite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Rhyolite include Decorative aggregates, Homes, Hotels, Interior decoration and Kitchens. Due to some exceptional properties of Limestone and Rhyolite, 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 Rhyolite include Arrowheads, As dimension stone, Building houses or walls, Construction aggregate, Cutting tool, For road aggregate, Knives.
More about Limestone and Rhyolite
Here you can know more about Limestone and Rhyolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Rhyolite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Limestone vs Rhyolite, 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, Rhyolite is available in grey, white, light black colors. Appearance of Limestone is Rough and Banded and that of Rhyolite is Banded. Properties of rock is another aspect for Limestone vs Rhyolite. The hardness of Limestone is 3-4 and that of Rhyolite is 6-7. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks.. 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 Rhyolite is colorless. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Rhyolite is Not Available. 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 Rhyolite is heat resistant, wear resistant.
