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.   
Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

Diabase vs Minette 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 Minette Reserves. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic 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 Diabase vs Minette information and Diabase vs Minette characteristics in the upcoming sections.

More about Diabase and Minette

Here you can know more about Diabase and Minette. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Minette consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Minette 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 Minette, 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, Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Diabase is Vesicular and that of Minette is Dull, Banded and Foilated. Properties of rock is another aspect for Diabase vs Minette. The hardness of Diabase is 7 and that of Minette is 5-6. The types of Diabase are Not Available whereas types of Minette 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 Minette is white. The specific heat capacity of Diabase is Not Available and that of Minette is Not Available. 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 Minette is heat resistant, impact resistant.
