Metallic Deposits - CliffsNotes

The ore minerals in most of the world's iron and manganese reserves were chemically precipitated in the ocean and accumulated on the sea floor. Placer deposits are heavy metallic minerals, such as iron or titanium minerals, or native gold or diamonds, that have been concentrated by wave or water action in a river or beach environment. The source of the minerals may be far upstream and contain very low amounts of these minerals.
