ResumoStratoid magnetite and skarn magnetite were mined at the San Guillermo mine district. Structural and textural evidence suggest that they formed by replacement of older rocks in Variscan orogeny times during a protracted process that begun with fluid flow and stratoid magnetite formation along thrusts. This was followed by the Brovales pluton emplacement probably controlled by an oblique shear zone. Exo and endoskarns with magnetite formed at this time, partly before and partly after complete crystallization of the pluton.
