Formation
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
  
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

Lamprophyre vs Blueschist 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. Lamprophyre vs Blueschist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lamprophyre and Properties of Blueschist. Learn more about Lamprophyre vs Blueschist in the next section. The interior uses of Lamprophyre include Decorative aggregates and Interior decoration whereas the interior uses of Blueschist include Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Lamprophyre and Blueschist, they have various applications in construction industry. The uses of Lamprophyre in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Blueschist include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Lamprophyre and Blueschist
Here you can know more about Lamprophyre and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lamprophyre and Blueschist consists of mineral content and compound content. The mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Blueschist includes Albite, Chlorite, Epidote, Garnet, Glaucophane, Lawsonite, Muscovite or Illite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Lamprophyre vs Blueschist, the texture, color and appearance plays an important role in determining the type of rock. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Lamprophyre is Dull, Banded and Foilated and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Lamprophyre vs Blueschist. The hardness of Lamprophyre is 5-6 and that of Blueschist is 3.5-4. The types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Blueschist are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lamprophyre is white while that of Blueschist is white to grey. The specific heat capacity of Lamprophyre is Not Available and that of Blueschist is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Lamprophyre is heat resistant, impact resistant whereas Blueschist is impact resistant, pressure resistant.
