Abstract Five cores were recovered on a traverse in the Lau Basin at 18°30′S crossing a supposed active spreading center. The sediments were subjected to selective chemical leaching for Mn, Fe, Cu, Zn, and As. Accumulation rates were determined using14C. These rates increase from west to east, reflecting the influence of volcaniclastic inputs from the Tonga- Kermadec Ridge. All elements display highest non-detrital accumulation rates closest to the supposed spreading center, suggesting a hydrothermal input to the sediments there. Variable hydrothermal inputs also influence the other cores.
