Fig. 1: Location map showing the samples from Mariana/Yap trenches. Results Total Hg and MMHg concentrations Total Hg concentrations in trench amphipods have an average of 547 ± 230 ng g−1(1 SD, 235 to 1070 ng g−1, dry weight, Supplementary Table1), which is comp...
The deepest spot in the Mariana Trench – the Challenger Deep – is roughly 10,900 meters deep. The spot is also the lowest place of the solid Earth surface, in contrary to Mount Qomolangma (Everest) which is the highest spot. Find out how the submersible got its na...
The near-trench transition to boninite magma generation required further partial melting of highly depleted mantle wedge sources but with a greater imprint of a slab-derived flux both of H2O and fluid-mobile trace elements14,19. The melt-depleted composition of this mantle wedge would have ...

Both the so-called FABs and the boninites formed at a significant distance from the incipient trench, not in a fore-arc position as previously claimed. The magmas erupted for 15 m.y. in some places, probably near the intersections between back-arc spreading centers and the arc. (5) As ...
Consequently, the distance between the KPR chain of volcanoes and the present-day trench is much greater than originally. The age of the igneous seafloor of the Amami-Sankaku basin was unknown at the time of drilling, but was thought to be as old as Cretaceous based on ages of the ...
