Formation

Formation

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
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.

Claystone vs Diabase Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Claystone and Diabase Reserves. Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Claystone vs Diabase information and Claystone vs Diabase characteristics in the upcoming sections.

Claystone 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. Claystone vs Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Diabase. Learn more about Claystone vs Diabase in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, 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 Claystone and Diabase, they have various applications in construction industry. The uses of Claystone in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Claystone and Diabase

Here you can know more about Claystone and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Diabase consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Diabase is available in dark grey to black colors. Appearance of Claystone is Rough and Dull and that of Diabase is Vesicular. Properties of rock is another aspect for Claystone vs Diabase. The hardness of Claystone is 3.5-4 and that of Diabase is 7. The types of Claystone are Claystone whereas types of Diabase are Dolerite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone is white while that of Diabase is black. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Diabase 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.Claystone is heat resistant, impact resistant whereas Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
