Definition
Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides
It is a metamorphic magnesium rich rock because it is composed of the mineral talc
Origin
Skye, Scotland

Etymology
From mugear + -ite
From 17th century, because of its greasy feel and use like a soap

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.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

Mugearite vs Soapstone 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 Soapstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mugearite and Properties of Soapstone. Learn more about Mugearite vs Soapstone in the next section. The interior uses of Mugearite include Floor tiles, Flooring, Homes and Hotels whereas the interior uses of Soapstone include Bathrooms, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Mugearite and Soapstone, 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 Soapstone include Manufacture of magnesium and dolomite refractories.
More about Mugearite and Soapstone
Here you can know more about Mugearite and Soapstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mugearite and Soapstone consists of mineral content and compound content. The mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene and mineral content of Soapstone includes Albite, Apatite, Biotite, Calcite, Carbonate, Clay Minerals, Hornblende, Ilmenite, Micas, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Mugearite vs Soapstone, 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, Soapstone is available in black, black to grey, green, grey colors. Appearance of Mugearite is Dull and Soft and that of Soapstone is Dull, Banded and Foilated. Properties of rock is another aspect for Mugearite vs Soapstone. The hardness of Mugearite is 6 and that of Soapstone is 1. 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 Soapstone are Not Available. 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 Soapstone is black. The specific heat capacity of Mugearite is 0.84 kJ/Kg K and that of Soapstone is 0.88 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 Soapstone is heat resistant, pressure resistant.
