堆晶体中硫化物熔体聚集模拟及对金川铜镍硫化物矿床成矿的指示

Key Points

• This research aims to explore the dynamics of sulfide accumulation in crystal piles within varying magma flow conditions.
• Conducted microfluidic simulations to analyze multiphase flow in the crystal piles.
• Examined the impact of porosity distribution on sulfide accumulation under different flow velocities.
• Investigated both vertical and horizontal flow environments.
• Sulfides accumulated primarily in discontinuous traps when the flow rate exceeded 0.01 m/s, reaching a volume fraction of 0.2 to 0.3.
• At low velocities, vertical flow facilitated enhanced sulfide accumulation.
• The degree of accumulation under low-speed conditions was mainly influenced by olivine particle size, with larger sizes promoting kinetic trapping.
