Caracterización mineralógica de bentonitas del Source Clay Repository

Abstract

Se caracterizan mineralógicamente 4 muestras bentoníticas del Source Clay Repository con el fin de conocer su composición mineralógica y relacionarla con su respuesta espectral en el rango 400- 2400 nm. Para ello se han utilizado dos técnicas analíticas distintas: difracción de Rayos-X (DRX) y espectroscopía VNIR-SWIR. Ambas técnicas nos muestran un alto contenido en esmectitas, con una cantidad muy pequeña de impurezas de cuarzo en las muestras APA y COU(V). También nos han permitido identificar el carácter di o trioctaédrico de las esmectitas, siendo dioctaédricas las muestras APA y SAN y triocatédricas COU(V) y SHE. La espectroscopía VNIR-SWIR muestra la gran similaritud de las dos muestras dioctaédricas mientras que evidencia el diferente contenido octaédrico de las otras dos muestras estudiadas: COU(V) marcada por su alto contenido en Fe y Mg, y SHE (hectorita sintética) en la que la presencia de Li produce rasgos claramente diferenciadores. Estos resultados indican que la espectroscopía VNIR-SWIR es una técnica útil en la identificación de esmectitas.
