Abstract
A study and characterization of sedimentary rock from the shores of the Metztitlán lagoon was carried out. Located in Eloxochitlán town of Hidalgo state, Mexico. The morphology of the crystals was determined by Scanning Electron Microscopy (SEM), with a pseudopolygonal shape and crystallite size of 100 μm. By Dispersive Energy Spectroscopy (EDS), microanalysis of chemical elements was performed. The average content of chemical elements in the sedimentary rock was C = 11.03%, O = 50.49%, Ca = 33.88%, Si = 3.63%, as the main ones. Which are present in the form of oxides, such as, CaO, SiO₂, MgO, Al₂O₃ and GaP. From these studies, it was possible to classify the sedimentary rock of an Impure Alloquímica composition, called dedrica, which is formed from sedimentation with an environmental alteration, characteristic of the land. By X-Ray Poweder Diffraction (XRD), the mineralogical phases of Alunite KAl₃ (SO⁴)(OH)₆, Cristobalite, Kaolinite Al₂Si₂O₅ and CaCO₃were determined.A study and characterization of sedimentary rock from the shores of the Metztitlán lagoon was carried out.
