Formation

Formation

Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Lamprophyre 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 Lamprophyre and Charnockite Reserves. Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions. 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 Lamprophyre vs Charnockite information and Lamprophyre vs Charnockite characteristics in the upcoming sections.

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