Timón, S. M.Moro Benito, M. C.Fernández Fernández, A.2017-03-022017-03-021995http://hdl.handle.net/10272/13395The 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.spaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/PyritePyrrhotiteArsenopyriteSilurianSedimentary sulfidesZamorajournal articleopen access
