When it comes to metallic minerals, there are several rock systems that are known to be rich in them. However, one rock system stands out as the most abundant in metallic minerals, and that is the igneous rock system.
Igneous rocks are formed from the solidification of magma or lava. They are classified into two types: intrusive and extrusive. Intrusive igneous rocks are formed when magma cools and solidifies beneath the Earth’s surface, while extrusive igneous rocks are formed when lava cools and solidifies on the Earth’s surface.
The igneous rock system is the richest in metallic minerals because of the high temperatures and pressures that are involved in the formation of these rocks. These conditions allow for the concentration of metallic minerals, such as copper, gold, silver, and platinum, to occur.
One of the most famous examples of an igneous rock system that is rich in metallic minerals is the Bushveld Igneous Complex in South Africa. This complex is known for its platinum group metals, which include platinum, palladium, and rhodium.
Another example is the Sudbury Basin in Canada, which is known for its nickel, copper, and platinum group metals. The Sudbury Basin is believed to have been formed by a meteorite impact, which created the conditions necessary for the concentration of metallic minerals.
In conclusion, the igneous rock system is the richest in metallic minerals due to the high temperatures and pressures involved in its formation. This system has produced some of the world’s most valuable metallic minerals, making it an important resource for the mining industry.
