Okinawa Trough, station P617 SC243: neritic sandy silt
North Pacific
Sediments
- Type
- Sediment
Surface marine sediment analysed by Ishikawa and Nakamura (1993); δ11B of modern sediments controlled by mixing of continental detritus (illite), marine smectite, biogenic carbonates and silica. Quaternary neritic sediment (detrital illite, chlorite, quartz and feldspar from Eurasia, biogenic carbonates).
