Hornfels vs Limestone

Definition

Definition

Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Formation

Formation

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Hornfels is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Hornfels vs Limestone 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 Hornfels and Limestone Reserves. Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. 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 Hornfels vs Limestone information and Hornfels vs Limestone characteristics in the upcoming sections.

Hornfels 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. Hornfels vs Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hornfels and Properties of Limestone. Learn more about Hornfels vs Limestone in the next section. The interior uses of Hornfels include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Hornfels and Limestone, they have various applications in construction industry. The uses of Hornfels in construction industry include For road aggregate, Roadstone 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 Hornfels and Limestone

Here you can know more about Hornfels and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornfels and Limestone consists of mineral content and compound content. The mineral content of Hornfels includes Andalusite and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Hornfels vs Limestone, the texture, color and appearance plays an important role in determining the type of rock. Hornfels is available in brown, dark greenish - grey, green, reddish brown 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 Hornfels is Dull and that of Limestone is Rough and Banded. Properties of rock is another aspect for Hornfels vs Limestone. The hardness of Hornfels is 2-3 and that of Limestone is 3-4. The types of Hornfels are Biotite hornfels 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 Hornfels is while that of Limestone is white. The specific heat capacity of Hornfels is 0.84 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.Hornfels is heat resistant, impact resistant, pressure resistant whereas Limestone is pressure resistant.
