A tungsten-182 and trace element perspective on the origin of the FOcal ZOne (FOZO) component

Key Points

• The FOZO component's origin is investigated through tungsten-182 isotopic compositions, leading to new geochemical insights.
• Key evidence indicates that tungsten-182 signatures differentiate the FOZO component from other sources, highlighting its uniqueness.
• Observational analysis of trace elements and tungsten isotopes explores geochemical signatures essential for understanding FOZO.
• Findings bolster theories about the Earth's mantle evolution, emphasizing the need for further research into isotopic variations.
