Resumen:

This communication provides the first-ever scientific study of the mineralogy and chemistry of magnetite of the Mg-skarn iron deposit of San Manuel, Serrania de Ronda in SW Spain. This iron deposit is hosted in marbles overlying migmatites found forming a tectonic slice along the southern contact of the Ronda ultramafic massif. Prograde and retrograde skam stages have resulted in zoning of magnetite, characterized by variations in the chemistry and typology of mineral inclusions. Using laser-ablation ICPMS we have measured the contents of trace elements in magnetite, fingerprinting the origin of the mineralizing fluid as related to the migmatites that originated during host emplacement of the upper mantle peridotites in the continental crust.
