"Mineral Sands Deposits: their complexity and need for .

The term "Mineral Sands" refers to sands which contain suites of minerals with high specific gravity (> 4 Specific Gravity) known as heavy minerals. Heavy minerals occurs as disseminated, associated or concentrated deposits within the sands. Found in an alluvial (old beach or river system) environment.

Sandstone is a sedimentary rock composed mostly of quartz sand, but it can also contain significant amounts of feldspar, and sometimes silt and clay. Sandstone that contains more than 90% quartz is called quartzose sandstone. When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstone.

2019-10-28 Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains. It is equally likely that some concentrations of heavy minerals (aside from the usual gold placers) exist within streambeds, but most are of a low grade and are relatively small.
