The genetic relationship between the Jinchuan Cu-Ni sulfide deposit and the near-by mafic-ultramafic intrusions is important for further exploration. Their above features suggest that the Jinchuan and Maocaoquan intrusions were derived from the same magma source with the same age. Maocaoquan mafic-ultramafic intrusions were possibly formed by earlier stage magma from the Jinchuan magma chamber, which contributed siderophile elements and olivine for later stage magma, thus forming the Jinchuan Cu-Ni sulfide deposit.
