Jordmetaller

Jordmetaller is a term used in some geological contexts to refer to a group of metallic elements that are commonly found in the Earth's crust. The precise definition can vary slightly depending on the scientific discipline, but it generally encompasses metals that are not considered rare or precious, and are often abundant in silicate rocks.

These metals are typically characterized by their relatively high melting points and densities. Common examples of jordmetaller include iron, aluminum, magnesium, and calcium. While these elements are essential components of many minerals and rocks, their extraction and processing are often significant industrial activities. Their abundance in the Earth's crust makes them economically important for various applications, from construction and manufacturing to agriculture and medicine.

The classification of metals can be complex, with overlapping categories like transition metals, alkaline earth metals, and post-transition metals. Jordmetaller often fall into these more specific classifications but are grouped together for broader geological or material science discussions. Understanding the distribution and properties of these common metallic elements is fundamental to studying the Earth's composition and its resources.
