Abstract
En este trabajo se estudian los caracteres geológicos y metalogénicos de la mineralización de cobres grises de Alpartir (Zaragoza), la cual se presenta re11enando una brecha de falla, principalmente en la Cuarcita Armoricana. La paragénesis pertenece al tipo q. Sb-Cu(Ag), con tetraedrita como mineral portador de la plata. Se propone que es un yacimiento hidrotermal, en relación aparente con el volcanismo permo-carbonífero de la Cordillera Ibérica. Los caracteres geoquímicos de las cuarcitas encajantes han puesto de manifiesto ciertas anomalías en determinados elementos metalogénicos, que podrían indicar la existencia de un supuesto contenido metálico en algunos niveles de la Cuarcita Armoricana.
In this paper the geological and metallogenic fcatures of the fahl-orcs of Alpartir (Zaragoza) are studied. The mineralization is filling a tectonic breccia, mainly in the Armoricana quartzite. The mineral association belongs to the q. Sb-Cu(Ag) type with tetrahedrite ore as silver-bearing mineral. It is proposed and hydrotermal origin for the mineralization, in relation with the permo-carboniferous volcanism of the Cordillera Ibérica. The geochemical fcaturcs of tbe quarzites have show sorne anornalies of metallogenic elements. That could point out a certain stock metal in sorne levels of the Armoricane quartzite.
