Resum
The aim of the present work is to synthesize and typify from a petrological-structural point of view the features of the most representative ore veins of Sn and W of the «salmantino-zamorana» peneplain. The following types have been discerned: a )Ore veins associated with ductile shear zones. b )Ore veins as a result of tension mechanisms. c )Ore veins conditioned by the shape of granitic bodies. d )Ore veins in relation with small-scale fracturing in an E-W direction. e )Ore veins associated with north-easterly faults. A brief description is also made of the mineral association in most of the ore veins.
