Definition
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Diabase and Talc carbonate
Here you can know more about Diabase and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Talc carbonate consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all . When we have to compare Diabase vs Talc carbonate, 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, Talc carbonate is available in colourless, grey, white colors. Appearance of Diabase is Vesicular and that of Talc carbonate is Soft. Properties of rock is another aspect for Diabase vs Talc carbonate. The hardness of Diabase is 7 and that of Talc carbonate is 1-2. The types of Diabase are Not Available whereas types of Talc carbonate 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 Talc carbonate is white. The specific heat capacity of Diabase is Not Available and that of Talc carbonate is 0.92 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 Talc carbonate is heat resistant, wear resistant.
