Definition
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar
Vogesite is a porphyritic alkaline igneous rock and is a variety of Lamprophyre which is dominated by essential amphibole, usually hornblende, and potassic feldspar

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

Diabase vs Vogesite 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 Vogesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Vogesite. Learn more about Diabase vs Vogesite in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Vogesite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Diabase and Vogesite, they have various applications in construction industry.

More about Diabase and Vogesite
Here you can know more about Diabase and Vogesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Vogesite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Vogesite 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 Vogesite, 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, Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Diabase is Vesicular and that of Vogesite is Dull, Banded and Foilated. Properties of rock is another aspect for Diabase vs Vogesite. The hardness of Diabase is 7 and that of Vogesite is 5-6. The types of Diabase are Dolerite whereas types of Vogesite 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 Vogesite is white. The specific heat capacity of Diabase is 0.84 kJ/Kg K and that of Vogesite is 0.84 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 Vogesite is heat resistant, impact resistant.
