detrital deposits
Placer or detrital deposits are composed of minerals that have been released by weathering and later have been transported, sorted, and collected by natural agencies into valuable deposits. Such minerals are usually of high specific gravity and are resistant to abrasion and weathering. Examples are gold, diamonds, platinum, tin (cassiterite), monazite, magnetite, and ilmenite, these last two being the common constituents of black sand.
