LAS ESPECTACULARES GEODAS DE GOETHITA TABULAR DE TORDELRÁBANO (PROVINCIA DE GUADALAJARA): ESTUDIO ESTRATIGRÁFICO Y PETROGRÁFICO

Abstract

Las espectaculares geodas de goethita tabular de la localidad de Tordelrábano (Provincia de Guadalajara) son de origen edáfico y se localizan en la parte alta de las facies Buntsandstein. Se tratan de unas geodas constituidas por unas envueltas carbonáticas y silíceas, en cuyo interior aparecen minerales férricos como el hematites y la goethita creciendo en forma tabular, inusual en este tipo de mineralizaciones. En este trabajo se ha realizado un estudio estratigráfico, para entender la formación de las geodas a partir de un encuadre geológico único y un estudio petrográfico para establecer un orden diagenético en la formación de estas. Para el estudio estratigráfico se ha levantado una columna estratigráfica en el afloramiento donde se encuadran las geodas. Se ha llevado a cabo un análisis microscópico a partir de una muestra recogida en campo a la que se le ha realizado una lámina delgada. Aplicándola técnicas de catodoluminiscencia con el fin de establecer un orden diagenético de la formación de los minerales constituyentes de las geodas.
