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. spa info:eu-repo/semantics/openAccess Rock magnetism Environmental magnetism Sediments Atapuerca Propuesta metodológica para la caracterización de la mineralogía magnética en estudios paloambientales: aplicación al yacimiento de Atapuerca info:eu-repo/semantics/article
