Formation

Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Charnockite vs Shonkinite 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 Charnockite and Shonkinite Reserves. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar. Shonkinite is a rare, dark-coloured and intrusive igneous rock which contains augite and orthoclase feldspar as its primary constituents. 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 Charnockite vs Shonkinite information and Charnockite vs Shonkinite characteristics in the upcoming sections.

Charnockite vs Shonkinite 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. Charnockite vs Shonkinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Charnockite and Properties of Shonkinite. Learn more about Charnockite vs Shonkinite in the next section.
