RESUMENArqueros, Algodones y Rodaíto son tres distritos argentíferos del norte de Chile que tuvieron gran importancia económica en el siglo XIX. Dado que fueron intensamente explotados en el siglo pasado, en la actualidad el principal testimonio mineralógico lo constituye la Colección Mineralógica Ignacio Domeyko del Museo Mineralógico de La Serena (Chile).El estudio de esta colección, junto con la revisión de la geología distrital de estos yacimientos, permite establecer las siguientes conclusiones: 1) los tres distritos son mineralizaciones filoDianas epitermales encajadas en rocas volcánicas y sedimentarias del Cretácico, y son asignables a los modelos de yacimientos argentíferos tipo «Comstock» o «Creede»; 2) las paragénesis estudiadas pueden asimilarse a la asociación Cu-Pb-Zn-Ag (e.g. Creede, Colorado, USA; Zacatecas, México); 3) la existencia de skutterudita y eritrina sugiere, sin embargo, un cierto carácter transicional respecto a otras asociaciones: Ag-Bi-Co-Ni-As (e.g. Cobalt, Ontario, Canadá) y Pb-Zn-Ag (Sb-As) (Coeur d'Alene, Idaho, USA: Freiberg, Alemania). Palabras clave: Colección mineralógica, Chile, plata y yacimientos epitermales.ABSTRACT Arqueros, Algodones and Rodaíto are silver districts from northern Chile that were of major economic importance during the XIX century. Since the deposits were extensively mined during the last century, at present, the main mineralogical record is kept at the «Co-lección Ignacio Domeyko», a major collection belonging to the Mineralogical Museum of La Serena (Chile).The study of the collection together with a revision of the local geology of the districts led to the following conclusions: 1) the districts are formed by Comstock/Creede-type epithermal silver-base metals deposits, which are hosted by volcanic and sedimentary rocks of Cretaceous age: 2) the studied parageneses can be ascribed to the Cu-Pb-Zn-Ag association (e.g. Creede, Colorado, USA; Zacatecas, Mexico); 3) the presence of skutterudite and erythrite suggests, however, a transitional character towards other mineralogical associations: Ag-Bi-Co-Ni-As (e.g. Cobalt, Ontario, Canada) and Pb-Zn-Ag (Sb-As) (Coeur d'Alene, Idaho, USA).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
