1.1 Definition

Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

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

5.1 Formation

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

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.

Laterite 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 Laterite and Hornfels Reserves. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. 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 Laterite vs Hornfels information and Laterite vs Hornfels characteristics in the upcoming sections.
