First advances in the geochemical characteristics of volcanics of outcrops of Antofagasta de la Sierra (province of Catamarca, Argentina)

Mostrar todas las versiones(2)

In different sectors of the Antofagasta de la Sierra micro-region (Catamarca Province, Southern Argentine Pune) outcrops of macroscopically very similar vulcanites (volcanic rocks with ratios of glass below 80%, sensu Aschero et al. 2002/2004) have been recorded. In order to differentiate between th...

In this instance, the initial results obtained from geochemical characterization, through Energy Dispersive X-ray Fluorescence, are presented. The vulcanites from different outcrops tend to show different concentrations for some elements. The results are promising and encourage further investigation into the application of geochemical methods for the differentiation and determination of the origin of these volcanic rocks.

En distintos sectores de la microrregión de Antofagasta de la Sierra (Provincia de Catamarca, Puna Meridional Argentina) se registran afloramientos de vulcanitas (rocas volcánicas con proporciones de vidrio menores a 80%, sensu Aschero et al. 2002/2004) macroscópicamente muy similares. Con el objetivo de diferenciarlas y aportar, de esta forma, a su identificación en el registro arqueológico, se aplicaron diversos métodos y técnicas sobre muestras de estas rocas procedentes de los distintos afloramientos. En esta instancia, se exponen los resultados obtenidos a partir de caracterización geoquímica por medio de Fluorescencia de Rayos X de Energía Dispersiva. Las vulcanitas procedentes de los diferentes afloramientos tienden a presentar disímiles concentraciones de ciertos elementos. Estos resultados son prometedores y estimulan a continuar investigando la aplicación de métodos geoquímicos en la diferenciación y determinación de la procedencia de estas rocas volcánicas. Cabe destacar que en el Noroeste Argentino los métodos geoquímicos fueron exclusivamente aplicados sobre una roca volcánica específica, la obsidiana, y aún no habían sido utilizados en otras rocas volcánicas anisótropas, con superficies, texturas y estructuras más irregulares.
