Thermodynamic numerical modeling of mantle magmatism-associated migration and enrichment of chromium, nickel, and platinum group elements

Key Points

• The aim is to quantitatively identify the key factors controlling the enrichment of chromium, nickel, and platinum group elements during mantle magmatism.
• Applied thermodynamic numerical modeling techniques combined with mass balance calculations.
• Analyzed typical critical metal deposits in China, including the Luobusa chromium deposit, Xiarihami nickel deposit, and Jinchuan platinum group elements deposit.
• Quantified the effects of melt and rock compositions as well as temperature and pressure on element distribution.
• Identified significant factors influencing the behavior of chromium, nickel, and platinum group elements during the magmatic process.
• Demonstrated a quantitative relationship between mantle melting processes and metal enrichment.
• Provided insights into the complex interactions involved in the magmatic processes leading to metal deposits.
