5 Formation

5.1 Formation

Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.

Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

Gritstone vs Anorthosite 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 Gritstone and Anorthosite Reserves. Gritstone or grit is a hard, coarse-grained, siliceous sandstone. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. 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.

More about Gritstone and Anorthosite

Here you can know more about Gritstone and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Anorthosite consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Gritstone vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Gritstone is Layered and Foliated and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Gritstone vs Anorthosite. The hardness of Gritstone is 6-7 and that of Anorthosite is 5-6. The types of Gritstone are Not Available whereas types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gritstone and Anorthosite is white. The specific heat capacity of Gritstone is 0.92 kJ/Kg K and that of Anorthosite 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.Gritstone is heat resistant, impact resistant, pressure resistant whereas Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
