5.1 Formation

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Rhyodacite 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 Rhyodacite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Limestone and Rhyodacite Reserves. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. Rhyodacite is an extrusive volcanic rock intermediate in composition between dacite and rhyolite. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Limestone vs Rhyodacite information and Limestone vs Rhyodacite characteristics in the upcoming sections.

More about Limestone and Rhyodacite

Here you can know more about Limestone and Rhyodacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Rhyodacite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Rhyodacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Limestone vs Rhyodacite, 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, Rhyodacite is available in black to grey, dark greenish - grey colors. Appearance of Limestone is Rough and Banded and that of Rhyodacite is Skeletal. Properties of rock is another aspect for Limestone vs Rhyodacite. The hardness of Limestone is 3-4 and that of Rhyodacite is 5.5-6. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Rhyodacite are Not Available. 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 Rhyodacite is black. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Rhyodacite is 1.12 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 Rhyodacite is heat resistant.
