Mercury isotopic composition of various ocean island basalts

The mercury isotopic composition of the basalts was measured in 2021 by MC-ICPMS, using a Nu Plasma Instrument. We report both mass-dependent ( δ202Hg) and mass-independent (Δ199Hg, Δ201Hg) isotopic composition of mercury. The mantle composition least affected by crustal recycling is estimated from...
