Formation

Formation
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.   
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

Soapstone vs Lamprophyre 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 Soapstone and Lamprophyre Reserves. It is a metamorphic magnesium rich rock because it is composed of the mineral talc. Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions. 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 Soapstone vs Lamprophyre information and Soapstone vs Lamprophyre characteristics in the upcoming sections.

Due to some exceptional properties of Soapstone and Lamprophyre, they have various applications in construction industry. The uses of Soapstone in construction industry include Manufacture of magnesium and dolomite refractories and that of Lamprophyre include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Soapstone and Lamprophyre

Here you can know more about Soapstone and Lamprophyre. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Lamprophyre consists of mineral content and compound content. The mineral content of Soapstone includes Albite, Apatite, Biotite, Calcite, Carbonate, Clay Minerals, Hornblende, Ilmenite, Micas, Plagioclase, Pyroxene, Quartz and mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Soapstone vs Lamprophyre, the texture, color and appearance plays an important role in determining the type of rock. Soapstone is available in black, black to grey, green, grey colors whereas, Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Soapstone is Dull, Banded and Foilated and that of Lamprophyre is Dull, Banded and Foilated. Properties of rock is another aspect for Soapstone vs Lamprophyre. The hardness of Soapstone is 1 and that of Lamprophyre is 5-6. The types of Soapstone are Metamorphic rock whereas types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Soapstone is black while that of Lamprophyre is white. The specific heat capacity of Soapstone is 0.88 kJ/Kg K and that of Lamprophyre 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.Soapstone is heat resistant, pressure resistant whereas Lamprophyre is heat resistant, impact resistant.
