👉 The term "magmatic" refers to a type of igneous rock that contains molten iron and nickel. Magmas are formed when magma rises from the Earth's mantle, typically due to heat or pressure. The process involves the movement of molten rock towards the surface of the Earth, often through fault lines or volcanic activity. The resulting magma is then condensed into solidified rocks, which can be either igneous or sedimentary. Magmas are an important part of the Earth's geological history
