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.

Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

Latite vs Blueschist 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 Blueschist Reserves. Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture. Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature. 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 Blueschist information and Latite vs Blueschist characteristics in the upcoming sections.

More about Latite and Blueschist

Here you can know more about Latite and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Blueschist consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Blueschist includes Albite, Chlorite, Epidote, Garnet, Glaucophane, Lawsonite, Muscovite or Illite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Latite vs Blueschist, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, green, grey, pink, white colors whereas, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Latite is Rough and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Latite vs Blueschist. The hardness of Latite is 5-5.5 and that of Blueschist is 3.5-4. The types of Latite are Rhomb porphyries whereas types of Blueschist are Metamorphic rock. 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 Blueschist is white to grey. The specific heat capacity of Latite is 0.92 kJ/Kg K and that of Blueschist 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.Latite is heat resistant, pressure resistant whereas Blueschist is impact resistant, pressure resistant.
