Definition
Harzburgite is a plutonic rock of the peridotite group consisting largely of orthopyroxene and olivine

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

Harzburgite vs Limestone 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. Harzburgite vs Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Harzburgite and Properties of Limestone. Learn more about Harzburgite vs Limestone in the next section. The interior uses of Harzburgite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Harzburgite and Limestone, they have various applications in construction industry. The uses of Harzburgite in construction industry include As dimension stone, Cobblestones and that of Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.
More about Harzburgite and Limestone
Here you can know more about Harzburgite and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Harzburgite and Limestone consists of mineral content and compound content. The mineral content of Harzburgite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Harzburgite vs Limestone, the texture, color and appearance plays an important role in determining the type of rock. Harzburgite is available in dark greenish - grey colors whereas, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Harzburgite is Rough and Shiny and that of Limestone is Rough and Banded. Properties of rock is another aspect for Harzburgite vs Limestone. The hardness of Harzburgite is 5.5-6 and that of Limestone is 3-4. The types of Harzburgite are Not Available whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Harzburgite and Limestone is white. The specific heat capacity of Harzburgite is 1.25 kJ/Kg K and that of Limestone is 0.91 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Harzburgite is heat resistant, pressure resistant, wear resistant whereas Limestone is pressure resistant.
