Formation

Formation
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.   
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.

Aplite vs Hornfels 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 Aplite and Hornfels Reserves. Aplite is a fine-grained granite composed mainly of feldspar and quartz. 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. 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 Aplite vs Hornfels information and Aplite vs Hornfels characteristics in the upcoming sections.

Aplite vs Hornfels 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. Aplite vs Hornfels characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Hornfels. Learn more about Aplite vs Hornfels in the next section. The interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Hornfels include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Aplite and Hornfels, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Hornfels include For road aggregate, Roadstone.

More about Aplite and Hornfels

Here you can know more about Aplite and Hornfels. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Hornfels consists of mineral content and compound content. The mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Hornfels includes Andalusite. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Hornfels, the texture, color and appearance plays an important role in determining the type of rock. Aplite is available in black, grey, orange, pink, white colors whereas, Hornfels is available in brown, dark greenish - grey, green, reddish brown colors. Appearance of Aplite is Veined or Pebbled and that of Hornfels is Dull. Properties of rock is another aspect for Aplite vs Hornfels. The hardness of Aplite is 6.5 and that of Hornfels is 2-3. The types of Aplite are Not Available whereas types of Hornfels are Biotite hornfels. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite is white while that of Hornfels is unknown. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Hornfels is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Aplite is heat resistant, wear resistant whereas Hornfels is heat resistant, impact resistant, pressure resistant.
