The ultra-low-grade Fe ore resource(content of total Fe is lower than 20%) hosted in mafic-ultramafic complexes in Chengde plays an important role in the iron production of Hebei Province,China.In order to investigate the ore-forming age and ore genesis of the Tiemahabaqin ultra-low Fe deposit,which makes a significant contribution to Chengde′s iron production,this study presents electron microprobe and 40Ar/39Ar isotopic data of the hornblendes from iron-bearing hornblendites.The electron… CONTINUE READING
