Mineral sands are classes of ore deposits containing valuable heavy minerals that commonly include titanium-bearing minerals like, zircon, garnet, and sillimanite. The source rocks which provide the heavy mineral sands determine the composition of the economic minerals. These are formed mostly in current or old beach environments by ...
Placers are mineral deposits formed by the mechanical concentration of minerals from weathered debris. Placers can be classified as eluvial, alluvial, eolian, beach, and fossil (paleo) deposit types. Monazite-bearing placer-type deposits can occur in residual weathering zones, beaches, rivers and streams, dunes, and offshore areas.
