In many parts of the southeastern U.S., dark-colored sands can be seen at beaches or beneath soil. These sands contain titanium, zirconium, and rare earth elements, which are considered critical mineral resources. Such sands are present in areas from the coast to a hundred miles or more inland beneath soil within the Atlantic Coastal Plain Province.

In the last two centuries, since the dawn of modern geology, heavy minerals have been used to investigate sediment provenance and for many other scientific or practical applications. Not always, however, with the correct approach. Difficulties are diverse, not just technical and related to the identification of tiny grains, but also procedural and conceptual. …
