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.   
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.

Diabase vs Blueschist 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 Blueschist Reserves. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature. 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 Blueschist information and Diabase vs Blueschist characteristics in the upcoming sections.

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 Blueschist include As dimension stone, Cobblestones, Rail track ballast, Roadstone.

More about Diabase and Blueschist

Here you can know more about Diabase and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Blueschist consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine 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 Diabase vs Blueschist, 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, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Diabase is Vesicular and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Diabase vs Blueschist. The hardness of Diabase is 7 and that of Blueschist is 3.5-4. The types of Diabase are Not Available 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 Diabase is black while that of Blueschist is white to grey.
