  • Although the four mafic-ultramafic intrusions in the Changshangou to Qingshuiquan area,Altyn Tagh,have the differences in petrology,petrography and geochemistry,they all formed in Middle-Ordovician,about 465Ma.Thereinto,the forsterite contents (Fo) in olivine of the Southern Qingshuiquan (SQ),Middle section of Changshagou (MC) and Huangtuquan (HT) intrusion,located in the south side of southern Altyn fault,vary from 95 to 85,and decrease progressively from east to west,that is higher than that (81-79) in olivine of the Northern Qingshuiquan (NQ) intrusion which is located in the north side of southern Altyn fault.According to the geochemical characteristics,magma evolution procedure and the relations between Nickel content and Fo in olivine,has been discussed in the geological background and potential magmatic Cu-Ni-PGE mineralization of these mafic-ultramafic intrusions.
