Definition
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.
  
Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides

Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
  
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.

Ganister vs Mugearite 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. Ganister vs Mugearite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Ganister and Properties of Mugearite. Learn more about Ganister vs Mugearite in the next section. The interior uses of Ganister include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Mugearite include Floor tiles, Flooring, Homes and Hotels. Due to some exceptional properties of Ganister and Mugearite, they have various applications in construction industry. The uses of Ganister in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar and that of Mugearite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Ganister and Mugearite
Here you can know more about Ganister and Mugearite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ganister and Mugearite consists of mineral content and compound content. The mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Ganister vs Mugearite, the texture, color and appearance plays an important role in determining the type of rock. Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Mugearite is available in black, brown, light to dark grey colors. Appearance of Ganister is Rough and that of Mugearite is Dull and Soft. Properties of rock is another aspect for Ganister vs Mugearite. The hardness of Ganister is 6-7 and that of Mugearite is 6. The types of Ganister are Not Available 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 Ganister is white while that of Mugearite is white to grey. The specific heat capacity of Ganister is 0.92 kJ/Kg K 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.Ganister is heat resistant, impact resistant, pressure resistant whereas Mugearite is heat resistant, pressure resistant, wear resistant.
