Formation

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.   
Porphyry is formed in two stages: the magma cools slowly deep within the crust or the magma is cools rapidly as it erupts from a volcano, creating small grains that are usually invisible to naked eye.

Mugearite vs Porphyry 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 Porphyry Reserves. Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides. Porphyry is a reddish-brown to purple igneous rock containing large phenocrysts of various minerals embedded in a fine-grained matrix. 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 Porphyry information and Mugearite vs Porphyry characteristics in the upcoming sections.

Mugearite vs Porphyry 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. Mugearite vs Porphyry characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mugearite and Properties of Porphyry. Learn more about Mugearite vs Porphyry in the next section. The interior uses of Mugearite include Floor tiles, Flooring, Homes and Hotels whereas the interior uses of Porphyry include Decorative aggregates and Interior decoration. Due to some exceptional properties of Mugearite and Porphyry, 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 Porphyry include Construction aggregate.

More about Mugearite and Porphyry

Here you can know more about Mugearite and Porphyry. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mugearite and Porphyry consists of mineral content and compound content. The mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene and mineral content of Porphyry includes Biotite, Chert, Feldspar, Garnet, Graphite, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Mugearite vs Porphyry, 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, Porphyry is available in black, brown, colourless, green, grey, red, rust, white colors. Appearance of Mugearite is Dull and Soft and that of Porphyry is Dull. Properties of rock is another aspect for Mugearite vs Porphyry. The hardness of Mugearite is 6 and that of Porphyry is 6-7. 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 Porphyry are Rhomb Porphyry. 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 Porphyry is white. The specific heat capacity of Mugearite is 0.84 kJ/Kg K and that of Porphyry is Not Available. 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 Porphyry is heat resistant, impact resistant.
