Picrite vs Latite 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 Picrite and Latite Reserves. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture. 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 Picrite vs Latite information and Picrite vs Latite characteristics in the upcoming sections.

The uses of Picrite in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, For road aggregate, Manufacture of magnesium and dolomite refractories, Roadstone, Used for flooring, stair treads, borders and window sills. and that of Latite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Picrite and Latite

Here you can know more about Picrite and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Picrite and Latite consists of mineral content and compound content. The mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite and mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Picrite vs Latite, the texture, color and appearance plays an important role in determining the type of rock. Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors whereas, Latite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Picrite is Rough and Shiny and that of Latite is Rough. Properties of rock is another aspect for Picrite vs Latite. The hardness of Picrite is 6.8 and that of Latite is 5-5.5. The types of Picrite are Oceanite whereas types of Latite are Rhomb porphyries. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Picrite and Latite is white, greenish white or grey. The specific heat capacity of Picrite is 0.88 kJ/Kg K and that of Latite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Picrite is heat resistant whereas Latite is heat resistant, pressure resistant.
