Spatial Microstructural Ordering of Expansive Clay Minerals por López Lara, T., Hernández Zaragoza, J. B., Carreón Freyre, D., Cerca, M., Rojas González, E., Minor Franco, A. G., Martínez Barrera, G., Salgado Delgado, R.

“…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. …”

Estudio de los principales mecanismos de fosilización en rocas de la formación cupido, barremiano-aptiano del noreste de México. por Gómez Mancha, Yesica Edith

“…Geochemically analyzed fossils indicate a relatively poor preservation of their original mineralogy due to a high mineral exchange that contrast with their relatively-well morphological preservation. …”

Caracterización geológica y geoquímica de fluidos en el sistema geotérmico Araró, Michoacán, México por Vigil Barrientos, Ana Julia

“…The identification and characterization of the minerals are made by light microscopy of the reflected light and the transmission, also to complement the mineralogical studies were used mineralogical determinants and qualitative techniques: X-ray diffraction, short-wave infrared spectroscopy and electron microscopy. …”

Caracterización por XANES, análisis mineralógico y aplicación industrial de un depósito de caolín de México por Torres, L. M., Vázquez, F., Garza, L. L., Martínez, A., López, W.

“…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. por Loera García, Eusebio Federico

“…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. …”
