Resumen de Contenido en plata de las mineralizaciones de plomo-zinc de la región del Valle de Alcudia (Ciudad Real). Implicaciones en la génesis de yacimientos hidrotermales de metales base
Fernando J. Palero Fernández, Agustín Martín Izard
In the Alcudia Valley region (Central-south of Spain), 5 differents types of Pb-Zn ores can be found. The most important of them is the 4 type, wich is made up by veins hosted in open fractures afecting the Precambrian-Lower Paleozoic metasedimentary sequences. The ore was formed during 3 main and 2 latter suscessives atapes. Ag content in ores of fourth types show a clear regional pattern, showing a preferntial distribution according with corridors where Ag conten increase towards residual thermal focus related with Hercinian granitics rocks.
