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.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

Diabase vs Jaspillite 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 Jaspillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Jaspillite. Learn more about Diabase vs Jaspillite in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Jaspillite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Diabase and Jaspillite, they have various applications in construction industry. The uses of Diabase in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Jaspillite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Diabase and Jaspillite
Here you can know more about Diabase and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Jaspillite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Jaspillite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Diabase vs Jaspillite, 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, Jaspillite is available in red, reddish brown colors. Appearance of Diabase is Vesicular and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Diabase vs Jaspillite. The hardness of Diabase is 7 and that of Jaspillite is 3. The types of Diabase are Dolerite whereas types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type. 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 Jaspillite is white. The specific heat capacity of Diabase is 0.84 kJ/Kg K and that of Jaspillite is 3.20 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 Jaspillite is heat resistant, impact resistant, wear resistant.
