峨眉大火成岩省白马层状岩体结晶分异和流动分选对钒钛磁铁矿成矿的控制

Key Points

• The central aim is to understand how crystallization differentiation and magma flow selection affect vanadium-titanium magnetite mineralization in the Baima layered intrusion.
• Reanalyzed whole-rock oxide data of the Baima intrusion.
• Examined the relationships between various oxide contents and ratios across major ore sections.
• Compared findings with similar studies on the Panzhihua intrusion.
• Identified systematic changes in oxide content and ratios across four main ore sections.
• Found that gravity flow selection significantly influences the formation of the vanadium-titanium magnetite layer.
• Noted that the undulating morphology of the magma chamber floor impacts mineral distribution and the formation of ore deposits.
