Scientists define sand as unconsolidated (loose) grains of minerals and rock that are less than 2.1 mm (0.08 inch) but more than .06 mm (0.006 inch) in diameter. Arenologists, scientists who study sand, can "read" the history of sand and tell its source, the climate of the area where it originated, the distance and environments it traveled through, and what …

Some magnetite specifically eroded from rocks, then was carried to the beach by rivers and is sometimes found in large concentrations in beach sand. Almost all sedimentary iron deposits contain hematite and magnetite along with other minerals. These materials are often in close association though both contain iron in different oxidation states.
