Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
  
Harzburgite 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 Harzburgite 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 Harzburgite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Harzburgite. Learn more about Limestone vs Harzburgite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Harzburgite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Limestone and Harzburgite, 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 Harzburgite include As dimension stone, Cobblestones.
More about Limestone and Harzburgite
Here you can know more about Limestone and Harzburgite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Harzburgite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Harzburgite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Limestone vs Harzburgite, 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, Harzburgite is available in dark greenish - grey colors. Appearance of Limestone is Rough and Banded and that of Harzburgite is Rough and Shiny. Properties of rock is another aspect for Limestone vs Harzburgite. The hardness of Limestone is 3-4 and that of Harzburgite is 5.5-6. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Harzburgite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Limestone and Harzburgite is white. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Harzburgite is 1.25 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 Harzburgite is heat resistant, pressure resistant, wear resistant.
