@article{10272/13395, year = {1995}, url = {http://hdl.handle.net/10272/13395}, abstract = {The Fe (Cu and Zn) sulfides of Latedo-Sejas are constituted of pyrite-pyrrhotite (sphalerite, chalcopyrite and arsenppyríte) and, on the basis of the ir textural and structural characteristics, three mineralógicaI stages have been differentiated: early sin-diagenetic (before phase 1), late sin-diagenetic (before or sinphase 1) and sin-phase 3. The first mineralogical phase consists of po (py, sp, cp) and the other two of py (po, cp, sp) and py±po (cp, sp). The Co and Ni contents in pyrites or pyrrhotites as well as the Co/NI ratio and the isotopic values, suggests that these sulfides have a sedimentary origin. Futhermore the formation T calculated using the arsenopyrite like a geothermometer is about 415°C.}, publisher = {Sociedad Geológica de España}, title = {Estudio mineralógico, químico e isotópico preliminar de los sulfuros de Fe (Zn y Cu) silúricos de Latedo-Sejas de Aliste (Zamora)}, author = {Timón, S.
