Trace element in titanomagnetite from Panzhihua Fe-Ti-V deposit:Implications for parental magma composition,evolution and ore genesis

摘要：

　　This work presents the first LA-ICP-MS analyses of titanomagnetite (Ti-Mt) from the lower ~1000 m of the mineralized Panzhihua gabbroic layered intrusion.Two distinct types of Ti-Mt are identified on the basis of Cr content.Both types display nearly constant trace element contents throughout the intrusion,except for Cr and Ni,which show an upward decrease in abundance.The high-Cr Ti-Mt is distinct in terms of Cr-Al-Fe3+ proportions from those from typical layered intrusions,but shows similarity to oxides found in Noril’sk-Talnakh and Jinchuan.The low-Cr magnetite displays lower Cr and broader range of Al and Fe3+ compared with Ti-Mt from other layered intrusions.
