5 Formation

5.1 Formation

Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

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.

Andesite vs Diabase 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 Andesite and Diabase Reserves. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. 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 Andesite vs Diabase information and Andesite vs Diabase characteristics in the upcoming sections.

More about Andesite and Diabase

Here you can know more about Andesite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Diabase consists of mineral content and compound content. The mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Igneous Rocks. When we have to compare Andesite vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Andesite is available in bluish - grey, grey, pink, yellow colors whereas, Diabase is available in dark grey to black colors. Appearance of Andesite is Dull and Soft and that of Diabase is Vesicular. Properties of rock is another aspect for Andesite vs Diabase. Hardness of Andesite and Diabase is 7. The types of Andesite are Icelandite whereas types of Diabase are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Andesite is white while that of Diabase is black. The specific heat capacity of Andesite is 2.39 kJ/Kg K and that of Diabase is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Andesite is heat resistant, pressure resistant, wear resistant whereas Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
