RT Journal Article T1 Las mineralizaciones ferríferas del coto minero San Guillermo(Jerez de los Caballeros, Badajoz, España) A1 Sanabria Orellana, Raúl A1 Casquet, César A1 Tornos Arroyo, Fernando A1 Galindo Francisco, Mª del Carmen AB Stratoid magnetite and skarn magnetite were mined at the San Guillermo mine district. Structural and texturalevidence suggest that they formed by replacement of older rocks in Variscan orogeny times during a protractedprocess that begun with fluid flow and stratoid magnetite formation along thrusts. This was followed by theBrovales pluton emplacement probably controlled by an oblique shear zone. Exo and endoskarns withmagnetite formed at this time, partly before and partly after complete crystallization of the pluton.
