5 Formation

5.1 Formation

Latite 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.

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.

Latite 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 Latite and Hornfels Reserves. Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture. 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 Latite vs Hornfels information and Latite vs Hornfels characteristics in the upcoming sections.

More about Latite and Hornfels

Here you can know more about Latite and Hornfels. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Hornfels consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Hornfels includes Andalusite. You can also check out the list of all Igneous Rocks. When we have to compare Latite vs Hornfels, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas, Hornfels is available in brown, dark greenish - grey, green, reddish brown colors. Appearance of Latite is Rough and that of Hornfels is Dull. Properties of rock is another aspect for Latite vs Hornfels. The hardness of Latite is 5-5.5 and that of Hornfels is 2-3. The types of Latite are Rhomb porphyries 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 Latite is white while that of Hornfels is unknown. The specific heat capacity of Latite is 0.92 kJ/Kg K and that of Hornfels is 0.84 kJ/Kg K.
