As the magma rises, various features can be formed. The magma below the surface is gradually pushed up from deep within the earth into fissures, and in some instances, it is even pushing the existing country rock out of its path. The process usually takes millions of years. Magma is a mixture of gas, crystals, and liquid rock. Magma is generally linked with various chemical compositions, and high temperature, as well as fluid properties. They are also less dense in comparison to the surrounding rocks explaining why they move upward. If the magma makes it to the surface, it forms extrusive igneous intrusions.
On the other hand, if it solidifies before reaching the continental surface, they form intrusive igneous. It implies that the igneous intrusions are formed as a result of the cooling and solidification of the magma before reaching the earth surface. The igneous rocks have coarse grains. This is because of the slow cooling of the magma, which also results in the formation of the phaneritic texture. The intrusive igneous rock formations are only manifested due to erosion and weathering. To that effect, drawing on a variety of sources, the paper will discuss igneous intrusion on the continental crust.
There are various forms of igneous intrusions on the continental crust formed as a result of cooling and solidification of the magma before reaching the earth surface. Over time, they are often visible on the Earth surface. The magma moves through the fractures and joints, as well as between the crystals of the solid rock of the crust. When it attains its freezing temperatures, it crystallizes. The structures formed beneath the Earth’s surface after the crystallization of magma include sills, dikes, stock, batholiths, laccoliths, phytoliths, and volcanic neck/pipe.
