Formation

Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

Charnockite vs Andesite 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 Andesite Reserves. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. 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 Andesite information and Charnockite vs Andesite characteristics in the upcoming sections.

Charnockite vs Andesite Characteristics
