Propuesta metodológica para la caracterización de la mineralogía magnética en estudios paloambientales: aplicación al yacimiento de Atapuerca Bógalo Román, Mª Felicidad Heller, F. Villalaín Santamaria, Juan José Calvo Rathert, Manuel Osete López, María Luisa Pérez González, Alfredo Rock magnetism Environmental magnetism Sediments Atapuerca A methodology is proposed, which gives information about the contents of ferrimagnetic and antiferromagnetic minerals with different domain structure in soils and sediments. Isothermal remanent magnetisation (lRM) acquired and measured both at room temperature and at low temperature (77K) provides data which define a set of new parameters: ARMlc provides information about the fraction of superparamagnetic ferrimagnetics in the studied samples; parameters G and g, respectively, inform about absolute and relative contents of goethite, and parameters B and b discern the fraction of goethite, in superparamagnetic state. The proposed methodology is applied to the study of cave sediments from the palaeo-anthropological site of Atapuerca. 2024-04-24T11:35:13Z 2024-04-24T11:35:13Z 2003 info:eu-repo/semantics/article 0213-683X http://hdl.handle.net/10259/9031 spa Geogaceta. 2003, n. 34, p. 107-110 https://sociedadgeologica.org/publicaciones/geogaceta/geogaceta-34-2003/ info:eu-repo/semantics/openAccess Sociedad Geológica de España
