"The sand-size fraction contains dominantly quartz, with lesser amounts of heavy minerals identified as goethite, magnetite, ilmenite, hematite, spinels, and pyroxenes. The sand grains are generally very angular to sub-rounded in shape. Grain angularity suggests that the sediments have not been transported over a great distance. However, the presence of rounded grains does imply a complex, ***polygenic*** origin and transport regime for the material. The minerals found within the sand-size fraction could have derived from two sources. "
