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.

Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.

Latite vs Chert 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 Chert Reserves. Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture. Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained 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 Latite vs Chert information and Latite vs Chert characteristics in the upcoming sections.

More about Latite and Chert

Here you can know more about Latite and Chert. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Chert consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Chert includes Quartz, Silicon. You can also check out the list of all Igneous Rocks. When we have to compare Latite vs Chert, 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, Chert is available in black, brown, green, grey, red, white colors. Appearance of Latite is Rough and that of Chert is Glassy or Pearly. Properties of rock is another aspect for Latite vs Chert. The hardness of Latite is 5-5.5 and that of Chert is 6.5-7. The types of Latite are Rhomb porphyries whereas types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Latite and Chert is white. The specific heat capacity of Latite is 0.92 kJ/Kg K and that of Chert is 0.74 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 Chert is heat resistant, impact resistant, pressure resistant, wear resistant.
