WebTools. In geology, a heavy mineral is a mineral with a density that is greater than 2.9 g/cm 3, most commonly referring to dense components of siliciclastic sediments. A heavy mineral suite is the relative percentages of heavy minerals in a stone. Heavy mineral suites are used to help determine the provenance and history of sedimentary rocks. 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. Therefore, the average heavy mineral yield in sandstones is about 1% but can be a lot lower in old/recycled sandstones. The individual properties of heavy minerals being very different from on…
