ABSTRACT Two marine concentrating processes operate to produce the heavy mineral deposits found on beaches in the vicinity of Apalachicola, Florida. The process operating in the more energetic Gulf of Mexico tends to remove the coarser grains from initial populations. This results in a relatively fine-grained black sand concentrate being …

The observed heavy mineral grains were significantly smaller than the quartz grains (Fig. 6 C–F) due to the effects of hydraulic equivalence and sorting. Zircon grains (density 4.7 g/cm 3) are much heavier than quartz (density 2.65 g/cm 3), and the density contrast is enhanced when buoyancy is taken into account.

To obtain minerals suitable for age-dating and other analyses, it is necessary to first reduce the mineral-bearing rock to a fine, sand-like consistency. Reducing whole rock requires crushing, grinding, and sieving. Ideally, the reduced material should range in size from 80- to 270-mesh (an opening between wires in a sieve). The …
