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.

Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

Diabase vs Migmatite 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 Migmatite Reserves. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components. 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 Migmatite information and Diabase vs Migmatite characteristics in the upcoming sections.

Diabase vs Migmatite 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 Migmatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Migmatite. Learn more about Diabase vs Migmatite in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Migmatite include Countertops, Flooring and Kitchens. Due to some exceptional properties of Diabase and Migmatite, 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 Migmatite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.

More about Diabase and Migmatite

Here you can know more about Diabase and Migmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Migmatite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Diabase vs Migmatite, 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, Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. Appearance of Diabase is Vesicular and that of Migmatite is Dull, Banded and Foilated. Properties of rock is another aspect for Diabase vs Migmatite. The hardness of Diabase is 7 and that of Migmatite is 5.5-6.5. The types of Diabase are Dolerite whereas types of Migmatite are Diatexites and Metatexites. 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 Migmatite is white. The specific heat capacity of Diabase is 0.84 kJ/Kg K and that of Migmatite is 0.79 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 Migmatite is heat resistant, pressure resistant.
