Mineralogía de la tierra fina y las arcillas en una secuencia de paleosuelos en la isla de Mallorca

Abstract

Se estudia una secuencia de paleosuelos superpuestos desarrollados en el Cuaternario. Se han diferenciado 18 horizontes a lo largo del perfil del suelo con una profundidad de 12,5 m. Para cada horizonte se ha cuantificado el contenido mineral de la tierra fina (< 2 mm) y los minerales de arcilla correspondientes a la fracción <0,002 mm. Los filosilicatos constituyen los minerales mayoritarios de estos horizontes. Los carbonatos de calcio son también muy abundantes, pero con importantes diferencias entre horizontes desde horizontes descarbonatados a otros en que constituyen la fracción mayoritaria. El cuarzo, los feldespatos potásicos y las plagioclasas son otros componentes comunes. Las illitas constituyen el mineral de arcilla más común, presentandose en forma pura y formando interestratificados con esmectitas. Las cloritas y caolinitas son otras especies de arcillas presentes en todos los horizontes. La composición mineral del conjunto de horizontes de estos paleosuelos pone de manifiesto un origen común de los materiales que los constituyen.
