Geological and Environmental Characterization and Near-Term Lease Potential of an Offshore Sand Resource Site for Use in Beach Nourishment Projects on Dauphin Island, Alabama. Appendices.

摘要

Since 1986, the Minerals Management Service (MMS) of the U.S. Department of Interior has directed the Gulf Task Force, composed of representatives of the states of Alabama, Mississippi, Louisiana, and Texas, to assess the occurrence and economic potential of hard mineral (non-fuel) resources in the Exclusive Economic Zone (EEZ) of those states. Sand and gravel, shell, and heavy minerals were the prominent hard minerals identified in the Gulf of Mexico EEZ, with sand being identified as the most abundant mineral and having the highest near-term leasing potential. The primary goal of present study by the Geological Survey of Alabama and the University of Alabama is to better describe the geometry and granulometry of an area 4 sand resource body delineated by Hummell and Smith (1995).
