Formation

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

More about Porphyry and Mugearite

Here you can know more about Porphyry and Mugearite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Porphyry and Mugearite consists of mineral content and compound content. The mineral content of Porphyry includes Biotite, Chert, Feldspar, Garnet, Graphite, Quartz, Silica and mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Porphyry vs Mugearite, the texture, color and appearance plays an important role in determining the type of rock. Porphyry is available in black, brown, colourless, green, grey, red, rust, white colors whereas, Mugearite is available in black, brown, light to dark grey colors. Appearance of Porphyry is Dull and that of Mugearite is Dull and Soft. Properties of rock is another aspect for Porphyry vs Mugearite. The hardness of Porphyry is 6-7 and that of Mugearite is 6. The types of Porphyry are Rhomb Porphyry whereas types of Mugearite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Porphyry is white while that of Mugearite is white to grey. The specific heat capacity of Porphyry is Not Available and that of Mugearite 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.Porphyry is heat resistant, impact resistant whereas Mugearite is heat resistant, pressure resistant, wear resistant.
