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 greater than ...

Why not just one number? The most common minerals in most sand samples are quartz and feldspar. Calcite and dolomite are common cementing minerals in sandstones. All of …

Heavy Minerals Mineral sands contain suites of minerals with high specific gravity known as 'heavy minerals'.
