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.
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

Diabase vs Trachyte 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 Trachyte characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Trachyte. Learn more about Diabase vs Trachyte in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Trachyte include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Diabase and Trachyte, 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 Trachyte include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Diabase and Trachyte
Here you can know more about Diabase and Trachyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Trachyte consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Trachyte includes Augite, Biotite, Feldspar, Hornblade, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Diabase vs Trachyte, 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, Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors. Appearance of Diabase is Vesicular and that of Trachyte is Banded. Properties of rock is another aspect for Diabase vs Trachyte. The hardness of Diabase is 7 and that of Trachyte is 6. The types of Diabase are Not Available whereas types of Trachyte are Not Available. 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 Trachyte is white. The specific heat capacity of Diabase is Not Available and that of Trachyte 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 Trachyte is heat resistant, impact resistant, wear resistant.
