Formation

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.   
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.

Diabase vs Gossan 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 Diabase and Gossan Reserves. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.. 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 Diabase vs Gossan information and Diabase vs Gossan characteristics in the upcoming sections.

Diabase vs Gossan 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 Gossan characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Gossan. Learn more about Diabase vs Gossan in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Gossan include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Diabase and Gossan, 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 Gossan include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.

More about Diabase and Gossan

Here you can know more about Diabase and Gossan. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Gossan consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Gossan includes Apatite, Augite, Biotite, Bronzite, Calcite, Chert, Epidote, Feldspar, Hornblende, Micas, Plagioclase, Pyroxene, Quartz, Sulfides, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Diabase vs Gossan, 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, Gossan is available in brown, brown- black, gold, green, rust colors. Appearance of Diabase is Vesicular and that of Gossan is Dull and Banded. Properties of rock is another aspect for Diabase vs Gossan. The hardness of Diabase is 7 and that of Gossan is 4-5. The types of Diabase are Not Available whereas types of Gossan are Translocated gossan and Leakage gossan. 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 Gossan is white to grey. The specific heat capacity of Diabase is Not Available and that of Gossan is 0.24 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 Gossan is heat resistant, impact resistant, pressure resistant.
