Definition
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar

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

Appinite vs Diabase 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. Appinite vs Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Appinite and Properties of Diabase. Learn more about Appinite vs Diabase in the next section. The interior uses of Appinite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Appinite and Diabase, they have various applications in construction industry. The uses of Appinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Appinite and Diabase
Here you can know more about Appinite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Appinite and Diabase consists of mineral content and compound content. The mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene 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 Appinite vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Diabase is available in dark grey to black colors. Appearance of Appinite is Dull, Banded and Foilated and that of Diabase is Vesicular. Properties of rock is another aspect for Appinite vs Diabase. The hardness of Appinite is 5-6 and that of Diabase is 7. The types of Appinite are Not Available 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 Appinite is white while that of Diabase is black. The specific heat capacity of Appinite is Not Available 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.Appinite is heat resistant, impact resistant whereas Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
