Abstract

The San Antonio ore deposit, near La Codosera, in the Badajoz province, Extremadura (Spain), belongs to the Sb-W-Hg mineral association, the existence of which had not been reported previously in the Iberian Peninsula.

The strata-bound mineralization occurs in a calcareous belt made up mainly of black limestones, intraformational breccias and calcareous shales, as well as some siliceous layers of Devonian age located in the SW of the Iberian massif, at the boundary between the Eastern Lusitanian-Alcudian and the Ossa Morena zones.

The peculiar geological setting of the ore body at the margin of an outer shelf, as well as some of its metallogenic and tectonic features, including its location at the shearing contact of two colliding plates, point out to an exhalative origin related with a Middle Devonian basic volcanism preceding the Hercynian orogeny.
