The heavy minerals have high average densities (of over 4.0 g cm −3) and are significantly heavier than the sand matrix (density 2.6 g cm −3). The large difference in the mineral densities can result in segregation of the heavy minerals during drilling and sample collection causing a biased composition of the recovered samples.
