Trace element contents in galena and sphalerite from ore deposits of the Alcudia Valley mineral field (Eastern Sierra Morena, Spain)

Trace element contents in galena concentrates and, particularly, sphalerite concentrates from the Alcudia Valley deposits have allowed us to discriminate between the different ore deposit types. Statistical analysis indicates that trace elements in galena and sphalerite are present mainly as micro-inclusions of various minerals. Sulfides in type E deposits show the widest variety and highest contents in trace elements. The possibility of using trace elements as tools for the characterization of the different types of ore deposits and their regional zoning is the main conclusion reached in this paper. This conclusion may be applied to exploration for these types of ore deposits in other areas with comparable geological characteristics.
