Fig. 6: Mo, Sr, and Pb isotopes of Pagan and NW Rota-1 volcanic rocks.

From: Molybdenum isotopes unmask slab dehydration and melting beneath the Mariana arc

Fig. 6

Plots of a δ98/95Mo vs. 87Sr/86Sr, b δ98/95Mo vs. 206Pb/204Pb and c δ98/95Mo vs. Δ8/4 for the Pagan and NW Rota-1 samples unaffected by amphibole fractional crystallization. Δ8/4 is the displacement from the Northern Hemisphere Reference Line in 208Pb/204Pb–206Pb/204Pb space74. The Sr-Mo isotopes of the depleted mantle (DM) are estimated according to the study on Pacific–Antarctic ridge basalts34. The Izu, other Mariana volcanic front, and average Mariana sediments data are also plotted for comparison. The ranges for the average 801 C AMOC5,8,52 run off of the diagrams. The symbols and data source are as in Fig. 3. SD standard deviation, AMOC altered mafic oceanic crust.
