Heavy mineral analysis - Wikipedia

Heavy minerals have highly variable stabilities with respect to transport/weathering but the combined effects of chemical weathering, transport and diagenesis 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 one …
