They consist of massive to semi-massive chromitites, frequently with nodular texture. Chromite chemistry is characterized by high Al2O3 contents and up to 0.4 wt.% TiO2, in agreement with a MORB affinity of the parental melt. Platinum-group element abundances are similar to most Al-chromitites reported in the literature except for an unusual enrichment in Pt and Pd. High Pt and Pd values were probably caused by late metamorphic alteration.engconference paperhttp://www.sga2011.ucn.cl/https://e-sga.org/meetings/sga-biennial-meetings/open access552.11(460.253)podiform chromititesplatinum-groupelementsIberian MassifPetrología2506.13 Petrología Ignea y Metamórfica
