Espinosa Física, Astronomía y Matemáticas fluorite Geochronology autoradiography alpha particles nuclear track detectors In this paper we present the uranium and thorium distribution analysis of several samples of the La Azul, an epithermal fluorspar depositin southern Mexico, using nuclear track methodology (NTM), in the alpha-autoradiography mode, by placing the mineral sample in contactwith a polycarbonate detector. This constitutes a non-destructive analysis, with sufficient sensitivity to provide valuable information abouttextural and paragenetic characteristics of the geological samples. The selected nuclear track detector was CR-39 (Landauer R°). The regionof interest of the geological samples was polished and put in contact with the detector material surface for 45 days in a vacuum chamber(10¡3 torr). After this period of time, the detectors were chemically etched, revealing the autoradiograph of the radioactive material. Theresults show a clear distribution of bands of uranium and thorium in the fluorite samples. This is valuable information for the genetic orgeochronological studies of the ore deposits. 2007 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57066313 https://www.redalyc.org/journal/570/57066313/ https://www.redalyc.org/journal/570/57066313/html/ https://www.redalyc.org/journal/570/57066313/57066313.epub https://www.redalyc.org/journal/570/57066313/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
