5.1 Formation

Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

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.

Mugearite 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 Mugearite and Chert Reserves. Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides. 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 Mugearite vs Chert information and Mugearite vs Chert characteristics in the upcoming sections.

The interior uses of Mugearite include Floor tiles, Flooring, Homes and Hotels whereas the interior uses of Chert include Decorative aggregates and Homes. Due to some exceptional properties of Mugearite and Chert, they have various applications in construction industry. The uses of Mugearite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Chert include Arrowheads, Construction aggregate, Cutting tool, Spear points.

More about Mugearite and Chert

Here you can know more about Mugearite and Chert. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mugearite and Chert consists of mineral content and compound content. The mineral content of Mugearite includes Olivine, 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 Mugearite vs Chert, the texture, color and appearance plays an important role in determining the type of rock. Mugearite is available in black, brown, light to dark grey colors whereas, Chert is available in black, brown, green, grey, red, white colors. Appearance of Mugearite is Dull and Soft and that of Chert is Glassy or Pearly. Properties of rock is another aspect for Mugearite vs Chert. The hardness of Mugearite is 6 and that of Chert is 6.5-7. The types of Mugearite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite 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 Mugearite is white to grey while that of Chert is white. The specific heat capacity of Mugearite is 0.84 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.Mugearite is heat resistant, pressure resistant, wear resistant whereas Chert is heat resistant, impact resistant, pressure resistant, wear resistant.
