· Heavy minerals are high-density components of siliciclastic sediments. They comprise minerals that have specific gravities greater than the two main framework components of sands and sandstones, quartz (s.g. 2.65) and feldspar (s.g. 2.54–2.76). In practice, heavy minerals are usually considered to be those with specific gravities
