Abundant iron oxides will also be found topographically below the contact of the Tertiary rocks with Cretaceous strata. From experience, the extensive ironstone cover associated with this setting is usually non-structured, although exceptions occur. The iron oxide which comprises these concretions has been derived mainly from the chemical weather-

Quartz. •••. Nastya22/iStock/Getty Images. Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides. The white color of quartz makes it easy to spot in many environments.

The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
