DSDP Site 261, sediments off the Sunda trench
Eastern Indian Ocean, southeast of Java (Leg 27), Océan Indien (eaux internationales)
Sediments
- Type
- Sediment
Muds, carbonates, sandstone and Mn-oxide-rich muds from DSDP Site 261 (Kurzweil et al., 2019), taken as the composition of sediments carried beneath the Sunda arc. Clearly heavier in Ti (+0.21 to +0.62 ‰) than the arc lavas (Kommescher et al., 2023).

| 0.418 ± 0.186 ‰ | 0.206 / 0.616 ‰ | 7 | drill-core sediment (bulk) Mean and standard deviation recalculated from 7 analyses, +0.206 to +0.616 (22-2-344.31m +0.206; 3-3-51.33m +0.227; 9-3-202.95m +0.246; 28-2-448.42m +0.475; 6-1-177.41m +0.547; 5-1-162.48m +0.610; 2-2-11.92m +0.616). Labels: core, section and depth below seafloor. The three heaviest samples (+0.55 to +0.62 ‰) are muds and the Mn-oxide-rich mud. | Kommescher et al.
