Significance of heavy minerals

Heavy minerals (minerals with a density greater than 2.89 g/cm ) have highly variable stabilities with respect to transport/weathering but the combined effects of chemical weathering, transport and diagenesis (and overall maturity) tend to decrease their percentage in the whole rock.
