Supplemental Material: The significance of (ultra)potassic mafic melts in the formation of postcollisional porphyry copper mineralization: An example from the Machangqing Cu-Mo deposit, southeastern Tibet

Key Points

• Postcollisional settings significantly influence the mineralization of porphyry copper deposits, such as Machangqing.
• Investigations identify ultrapotassic mafic melts as crucial for enhancing copper mineralization in the studied deposits.
• Field data and geological analysis were employed to establish the relationship between mafic melts and mineralization processes.
• Understanding the interactions between these melts and mineral deposits is essential for effective mining and resource management.
