Spatial Microstructural Ordering of Expansive Clay Minerals
Published 2018“…The volumetric change within soils containing expanding clays depends upon their spatial ordering and their mineralogy. Sothis work studies the spatial microstructural ordering and mineralogy of different expanding clays in order to correlate them with some of their geotechnical properties (plasticity, classification, andexpansion).TheclaymicrostructurewasobtainedusingX-ray diffraction, and sweeping electronic microscopy. …”

Caracterización por XANES, análisis mineralógico y aplicación industrial de un depósito de caolín de México
Published 2009“…ABSTRACT A kaolin obtained from Villa de Reyes, a region near to San Luis Potosí (México) was characterized by means of X-ray powder diffraction (XRD, optical microscopy (OM), scanning electron microscopy (SEM), X-ray fluorescence (XRF), X-Ray Absorption Near Edge Spectroscopy (XANES), thermal analysis (DTA/TGA), dilatometry (DIL), and chemical analysis. Mineralogical and morphological characteristics of the mineral are presented. …”

Vulcanismo en la secuencia evaporítica de la Formación Minas Viejas, Galeana N.L.
Published 2016“…Because the rocks are rich in carbonates such as calcite, dolomite and siderite, this added to the massiveness of the bodies, led to the hypothesis that the rocks were carbonatites within the Minas Viejas Formation. However, mineralogical and geochemical studies have ruled out as carbonatites that they are not carbonatitic rocks. …”
