Extremely light Mo isotope compositions of the lower continental crust caused by fluid leaching

Key Points

• Fluid leaching leads to extremely light molybdenum isotope compositions observed in the lower continental crust, affecting geochemical signatures.
• The study shows that these variations result from elemental transport processes over time, influencing crustal evolution.
• Geochemical analysis identified specific changes in mo isotope compositions linked with fluid interactions.
• Understanding these processes is crucial for broader insights into lower crust dynamics and elemental cycling.
