1990
Estudios Geologicos
Several size-fractions were centrifuged from the Aljibe sandstones to determinate both, nature and genesis of the cement. These samples are been analized by X-ray power diffraction, infrared spectroscopy, differential thermal analysis, termogravimetry and scanning electron microscopy. Two types of kaolinite were distinguished: Detrital kaolinite with low values of crystalIinity and b-parameter and authigenic kaolinite with higher values of crystallinity and b-parameter. Dickite is also presente
