Resumen

In the Lumbrales deposit (Salamanca Spain) have been recognised different sulphide belonging, partially, or wholly, to the system Sn-Cu-Fe-Zn-Mo-Bi-Ag-As-S. Replacement, exsolution and colloidal textures have been observed. As content of Arsenopyrite range between 34 and 37%, pointing out greatest temperature an crystallization of this assemblages (500-615ºC). Temperatures between 500-300ºC are deduced by Stannite-Stannoidites and Stannoidite-Mawsonite pairs and between 200-70ºC by the presence of Bornite-Chalcopyrite-Tenantite-Diagenite with colloidal textures.
