WebApr 11, 2024 · When we talk about placer deposits meaning, it is a natural concentration of heavy minerals induced by the effect of gravity on moving particles. When heavy, stable minerals are liberated from their matrix by the mechanism of weathering, they are slowly washed downslope into streams which rapidly winnow the lighter matrix. 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…
