Item Estudio de la variabilidad isotópica del oro proveniente del Distrito Minero Puerto Nare-Puerto Berrío, departamento de Antioquia mediante la técnica de espectrometría de masas con plasma de acoplamiento inductivo (ICP-MS)(Universidad Santiago de Cali, 2023) Álzate Ríos, Alejandra; Ríos Acevedo, Jhon Jairo (Director); Ruiz Solano, Verónica (Directora)In the study of the elemental and isotopic variability of gold, masses ranging from 9Be to 238U were selected, comprising a total of 64 elements, these elements include many isotopes that mark the characteristics of each particle studied. The collection of the samples was carried out in the Antioquia area of the Puerto Nare-Puerto Berrio district, and the elemental and isotopic quantification of the gold collected was executed by means of a previous analysis by X-ray Microfluorescence for major and minor elements, and finally by the technique of Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for the study of the isotopic variability. The data obtained were statistically processed using specialized software for the generation of multivariate plots, The results revealed that there was a wide isotopic variability in the gold samples with a characteristic profile of 44 elements of which the most distinctive were 75As, 181Ta, 47Ti, 52Cr, 191Ir, 45Sc238U, 56 Fe, 95Mo, 140Ce, 63Cu, 139La111Cd, 66 Zn, 201Hg, 151Eu, 59Co, 51V, 72Ge, 191Ir, 45Sc; demonstrating the usefulness of the ICP-MS technique for this study, the findings will serve as a basis for future research in the field of isotopic geochemistry and will contribute to the sustainable development of mining activity in the region.
