Formation

Formation
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.   
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Anthracite vs Charnockite 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 Anthracite and Charnockite Reserves. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, 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 Anthracite vs Charnockite information and Anthracite vs Charnockite characteristics in the upcoming sections.
