Formation

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

Gossan 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 Gossan and Diabase Reserves. Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.. 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 Gossan vs Diabase information and Gossan vs Diabase characteristics in the upcoming sections.

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

More about Gossan and Diabase

Here you can know more about Gossan and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gossan and Diabase consists of mineral content and compound content. The mineral content of Gossan includes Apatite, Augite, Biotite, Bronzite, Calcite, Chert, Epidote, Feldspar, Hornblende, Micas, Plagioclase, Pyroxene, Quartz, Sulfides, Zircon and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Metamorphic Rocks. When we have to compare Gossan vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Gossan is available in brown, brown- black, gold, green, rust colors whereas, Diabase is available in dark grey to black colors. Appearance of Gossan is Dull and Banded and that of Diabase is Vesicular. Properties of rock is another aspect for Gossan vs Diabase. The hardness of Gossan is 4-5 and that of Diabase is 7. The types of Gossan are Translocated gossan and Leakage gossan whereas types of Diabase are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gossan is white to grey while that of Diabase is black. The specific heat capacity of Gossan is 0.24 kJ/Kg K and that of Diabase is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Gossan is heat resistant, impact resistant, pressure resistant whereas Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
