Formation
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.
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.

Oolite 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. Oolite vs Mugearite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oolite and Properties of Mugearite. Learn more about Oolite vs Mugearite in the next section. The interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Mugearite include Floor tiles, Flooring, Homes and Hotels. Due to some exceptional properties of Oolite and Mugearite, they have various applications in construction industry. The uses of Oolite in construction industry include Cement manufacture, Cobblestones, Landscaping and that of Mugearite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Oolite and Mugearite
Here you can know more about Oolite and Mugearite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Mugearite consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt 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 Oolite vs Mugearite, the texture, color and appearance plays an important role in determining the type of rock. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas, Mugearite is available in black, brown, light to dark grey colors. Appearance of Oolite is Rounded and Rough and that of Mugearite is Dull and Soft. Properties of rock is another aspect for Oolite vs Mugearite. The hardness of Oolite is 3-4 and that of Mugearite is 6. The types of Oolite 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 Oolite is white while that of Mugearite is white to grey. The specific heat capacity of Oolite 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.Oolite is heat resistant, wear resistant whereas Mugearite is heat resistant, pressure resistant, wear resistant.
