Geochronology and geochemical evidence for a magmatic arc setting for the Ni-Cu mineralised 1.79Ga Kleva gabbro-diorite intrusive complex, southeast Sweden
Magmatic Ni-Cu sulphide deposits are commonly associated with mafic rocks within the marginal areas of Archean or Proterozoic cratons. The Kleva Ni-Cu sulphide deposit in southeast Sweden is hosted by gabbro-diorite rocks and is sandwiched between two Palaeoproterozoic magmatic arcs: the Transscandinavian Igneous Belt (TIB) and the Oskarshamn-Jonkoping Belt (OJB).
