Abstract

Abstract

After using ICP-AES to analyze clay fraction of the samples of Croe DGKS9603 which was taken from the middle Okinawa Trough, the conclusions are obtained as follows: the down variation of the element contents is caused by the paleoclimate and paleoenvironmental evolution; its material source varies clearly, biogenic source is the major source during 45~43 and 11.2~0 ka BP respectively; volcanic source is dominant during 43~41 ka BP and epicontinental source is the most important provenance during 41~11.2 ka BP.Additionally, the seven cold events E3, YD, H1, LGM, H2, H3, H5 are recorded clearly in Core DGKS9603, and the core is probably influenced by three volcanic events A, B, C.
- Okinawa Trough,
- sediment provenance,
- paleoclimate
