Characterıstics of Some Heavy Minerals from Egyptian Black Sands

The mineralogical characteristics and composition of zircon, amphiboles and pyroxenes which are common heavy minerals in Egyptian black sands have been determined. The minerals can be used for genetic and provenance studies. They indicate that the black sands were derived from the Nile sediments which were derived from the igneous and metamorphic complex along the upper reaches of the Nile.
