英文摘要 | The concentration of Cu is crucial to the formation of porphyry Cu deposits. However, key petrologic evidence for the origin of Cu-rich magmas is scarce. Here, we describe newly discovered Cu-rich mafic porphyritic enclaves (CMPEs) with accumulated phenocrysts, porphyritic textures and disseminated sulfide minerals in a Carboniferous tonalite pluton in the Sangnan area, East Junggar. These CMPEs have diagnostic petrologic, geochronologic and geochemical signatures that indicate they are intruded globules of Cu-rich mafic magma. These signatures include microgranular elongated laths of zoned plagioclase, needle-shaped zircon, poikilitic K feldspar, skeletal intergrowths of chalcopyrite and epidote, sharp contacts and different geochemical compositions than the host tonalite. They also display slight younger zircon U-Pb age but similar hornblende formation depths with their host tonalites. The host tonalites are talc-alkaline and adakitic, whereas the CMPEs are high-K talc-alkaline and dioritic and have the geochemical signature of normal arc rocks. |
