5 Formation

5.1 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.

Felsite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Diabase vs Felsite 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 Felsite Reserves. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition. 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 Felsite information and Diabase vs Felsite characteristics in the upcoming sections.

More about Diabase and Felsite

Here you can know more about Diabase and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Felsite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Igneous Rocks. When we have to compare Diabase vs Felsite, 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, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Diabase is Vesicular and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Diabase vs Felsite. The hardness of Diabase is 7 and that of Felsite is 5-5.5. The types of Diabase are Not Available whereas types of Felsite 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 Felsite is white. The specific heat capacity of Diabase is Not Available and that of Felsite is 0.92 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 Felsite is heat resistant, impact resistant.
