Formation

Formation

Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

Diabase 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 Diabase and Lamprophyre Reserves. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. 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 Diabase vs Lamprophyre information and Diabase vs Lamprophyre characteristics in the upcoming sections.

Diabase vs Lamprophyre 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. Diabase vs Lamprophyre characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Lamprophyre. Learn more about Diabase vs Lamprophyre in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Lamprophyre include Decorative aggregates and Interior decoration. Due to some exceptional properties of Diabase and Lamprophyre, they have various applications in construction industry. The uses of Diabase in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Lamprophyre include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Diabase and Lamprophyre

Here you can know more about Diabase and Lamprophyre. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Lamprophyre consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Diabase vs Lamprophyre, the texture, color and appearance plays an important role in determining the type of rock. Diabase is available in dark grey to black colors whereas, Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Diabase is Vesicular and that of Lamprophyre is Dull, Banded and Foilated. Properties of rock is another aspect for Diabase vs Lamprophyre. The hardness of Diabase is 7 and that of Lamprophyre is 5-6. The types of Diabase are Dolerite 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 Diabase is black while that of Lamprophyre is white. The specific heat capacity of Diabase is 0.84 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.Diabase is heat resistant, impact resistant, pressure resistant, wear resistant whereas Lamprophyre is heat resistant, impact resistant.
