    Contribución a la caracterización estructural y geoquímica de las mineralizaciones de hierro en el sector El Palmor, Magdalena
    (Universidad EAFIT, 2021) Castro Burgos, Juan Camilo; Coronado Patiño, Andy; Beltrán Triviño, Alejandro Iván
    In the village of El Palmor (Ciénaga, Magdalena), there are important manifestations of iron presented with form of alluvial deposits and tabulate bodies on the Anortositas unit of the Sevilla river, which have not yet defined the existence of a possible structural control on the seams, neither a chemical classification of mineralizations. Four samples of iron were taken, join with structural information of the zone; the main purpose was identified mineral’s presents, iron’s concentration percentage, and to identify the origin of these deposits, off course whether there is any structural implication on the location of the mineralized bodies. The samples were characterized by two laboratory tests (1) X-ray diffraction analysis (XRD) to corroborate the existence of kaolinite / dikite, magnetite, hematite and goethite and (2) X-ray fluorescence (XRF) for show Fe2O3 concentrations of approximately 17%. Therefore, it was inferred that iron declarations were associated with the formation of anortositic rocks, which by fractional crystallization of immiscible fluids rich in Fe and Ti are trapped between the crystalline mesh, which in turn they are accumulated by the phenomenon of filter pressing and subsequently mobilized to areas of low pressure, in this case possibly to the Sevilla guideline.
