Minerals are those limited resources extracted from the earth or the sea to serve civilization. Some minerals are discussed elsewhere, including resource metals, precious metals, metalloids,and fossil fuels. There are several other categories of minerals, examined here. Note that these categories have a lot of overlap, but this is a general sorting.

Many limited resources are chemical elements. For a roadmap of the elements, see the Periodic Table.
