Gneiss vs Laterite


Definition

Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas   
Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks

Formation

Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.   
Gneiss is a high grade metamorphic rock i.e. it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of Gneiss forms from volcanic rock, shale or granitie.

Laterite vs Gneiss 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 Gneiss Reserves. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. 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 Gneiss information and Laterite vs Gneiss characteristics in the upcoming sections.

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

More about Laterite and Gneiss

Here you can know more about Laterite and Gneiss. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Gneiss consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene and mineral content of Gneiss includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Gneiss, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Gneiss is available in black, brown, pink, red, white colors. Appearance of Laterite is Rough and Banded and that of Gneiss is Foliated. Properties of rock is another aspect for Laterite vs Gneiss. The hardness of Laterite is 2 and that of Gneiss is 7. The types of Laterite are Not Available whereas types of Gneiss are Augen Gneiss, Henderson Gneiss, Lewisian Gneiss, Archean and Proterozoic Gneiss.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite and Gneiss is white. The specific heat capacity of Laterite is Not Available and that of Gneiss is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Laterite is heat resistant, pressure resistant whereas Gneiss is heat resistant, pressure resistant, scratch resistant, wear resistant.
