These heavy mineral sands can be black or red in color, depending on the dominant heavy mineral (magnetite vs garnet). Heavy mineral sands include ore minerals that may be concentrated sufficiently to form economic deposits called placer deposits. Placer deposits can form in alluvial channels, on beaches, or on marine abrasion surfaces.
